Also this reviews will be accompanied by a section with graphs of technical measures of the most important parameters.
There is no such thing anywhere else, as far as I know. Not even the manufacturers themselves detailed the technical features of their own devices at this level.
This new section has been developed for an objective comparison of different devices.
In order to avoid interpreting the measurements incorrectly, it is very important to read the warnings carefully the first time.

The Korting Royal Syntektor 55W is the most prestigious model made by Leipzig's factory that year.
We already restored some Korting Royal Syntekor and while listening we were amazed by the
unusual dynamic characteristics. Also the 55W proved itself up to expectations. The high volume listening of this device is extremely rewarding and often surprising.
All this due to two elements: the transducers and a particular circuitry of the final stage.
The main (loud)speaker is a fabulous Isophon P23/25/105, with an AlNiCo magnet of 10500 Gauss and a linear response from 65 Hz to 10 kHz. It can withstand strong mechanical stresses and moreover it is fitted in a solidly built piece of forniture.
A 17 cm Medium adds brilliance on 900
1200 Hz range, the most important one to have a great experience while listening.

Not least the two big electrostatic tweeter, in plain view: their surface is very wide when compared with others usually placed on radios.

Moreover, let's talk about two little circuit's tricks: an oversize output transformer, making it very difficult to reach saturation and an unusual two power pentodes EL84's drivers.

As in the photo (9) the preamplifier stage is entrusted to a variable slope EF89 pentode that controls directly the first EL84 grid. Thereafter the signal is sent to the EABC80 triode's grid which dephases it of 180 degrees and then sends it to the second EL84.
Such circuits allows a high control voltage of the two final valves which can reveal all their power.

Also the FM section is unusual: the detector stage is syncrhronous, thanks to this, distortion is very low. Besides, you can select two levels of circuit sensitivity to avoid the detector stage saturation.

Conclusions: just one, this device must be listened at high volumes to fully enjoy its largeness.

The Royal Syntektor 55W recondings are made to highlight its very notable dynamic characteristics. Anyway these recordings don't let us appraise the impact from listening at high/loud volume with this device. We get only a perception of its quality.

Korting Royal Syntektor 55W

Korting Royal Syntektor 55W

The first track is “I've been loving you too long” by Otis Redding, recorded in 1965, written with Jerry Butler and inspired by love problems Otis was going through at the time. At Monterey Festival in 1967 audience was thrilled by Jimi Hendrix, who set on fire his handpainted Stratocaster at the end of his exhibition and Otis Redding, the most charismatic voice of Soul music. Few months later, Otis and his bandmates will die in a plane crash at Lake Monona, Wisconsin. My favourite cover of the song is the one by Ike & Tina Turner.
The second track is one of Cesária Évora's masterpieces, “Isolada”, written in 2003, first track of the album "Voz d'amor". Cesária's smooth voice dives you into Cabo Verde's atmosphere and in Morna, a music genre typical of these islands in which the main instruments are violão and rabeca (guitar and violin). Rhythm is slow and the composition usually monotonous. The main composer was Eugénio de Paula Tavares. The archipelago was used as a headquarter for slave trade between Africa and America; after the abrogation of slavery in Portuguese Empire, recurring droguths and desertification, which led to famine and plagues, natives inhabitants were forced to leave. This social background gave birth to Morna.
The third track is from Tosca, “Vissi d'arte” by Giacomo Puccini performed by Maria Callas, stage name of American-born Greek Anna Maria Cecilia Sophia  Kalogeropoulos, one of the most renowned opera singers of all times.
The Soprano has the highest vocal range of all female voice types, higher than Mezzosoprano and
Contralto, it requires a range of two octaves and a strong virtuosity, but Callas was a Coloratura soprano, she was able to perform roles as mezzosoprano, soprano leggero and soprano lirico. Not by chance she is still remembered as “La Divina”.

The fourth track is the catchy song by Eros Ramazzotti “Più bella cosa”. The song is dedicated to Michelle Hunziker, who he met at the time, but also (mainly) to Music, Eros' first true love that he will celebrate in many other songs. 
The lyrics there are clear references to memories and emotions (thrills) of his past rather than his love with Michelle.
The last track is one of Queen's most famous songs, “We will rock you”. Its history is really interesting: in a 1977 concert the band felt the crowd so engaged while singing along. They felt people had no room to dance and move freely, the only thing they could do was to clap hands, to stomp with feet and to sing. Hence “We will rock you” was born, a song about three ages of man:
the child, the grown-up and the elderly.

HISTORY

Körting-Radio-Werke Oswald Ritter was founded by Karl Oswald Max Ritter after leaving Dietz & Ritter GmbH in 1940.
At they beginning it produced radio receivers, transformers and electronic devices.
Körting branded
radio receivers have great success thanks to their high-quality.

After World War II, the company ventures with Carl Zeiss but in 1946 productions volumes drop due to the company's decommissioning.
In 1948 it is seized and transferred to public property and
managed by VEB Radio and Telecommunications Technology.

In 1949 Ritter moves to Upper Bavaria with some of his employees and in 1951, with a 5 millions DM lended by Bayerische Staatsbank, he acquires Belwe GmbH in Grassau, a producer of flatirons, toasters and little lamps, expanding the production to radios, speakers and electro-medical devices.

Körting's sales in West Germany are low compared to its competitors and the internal bank orders Gerhard Böhme to reorganize the company at the beginning of 1953. Oswald Ritter resigns as an associate in the summer of 1953 and Böhme becomes the company's manager.

In 1955 Ritter definitively leaves the company and dies on October 2nd, 1959 after a long illness.

The company agrees a deal with Neckermann, an important mail-order company in Frankfurt.
Neckermann nuys and sells all the televisions and radios with the brand Neckermann-Körting.
In 1957, Körting laucnhes the Dynamic 830W, the first radio in the world with dynamics expander.

From 1952 to 1964 sales are 7-times higher.
In 1963 and in 1964, Körting has to increase its
capabilities due to increased sales. In quick succession the company opens new branches in Grödig, near Salzburg, Möbelwerke Wallerstein and Körting-Italiana in Pavia. In this period Körting produces devices for Kuba-Imperial , Elac , Blaupunkt and Siemens.

In 1970, Körting makes a deal with Yugoslavian Gorenje to build televisions in their headquarters in Slovenia.

In 1972 Kuba ceases production, followed by Elac in 1978, and Karstadt takes over Neckermann, interrupting the cooperation with Körting.

In 1978 Körting filed for bankruptcy , on September 1st 1978 Gorenje acquires the main factory in Grassau, but at the end of March 1983 also Gorenje Körting Electronic goes bankrupt.

MEASURED TECHNICAL FEATURES

IMPORTANT REMARK
(to be read carefully at least the first time)

  1. The following measures have been carried out in order to compare, from an electrical point of view, the devices that will be reviewed on this site. It is not possible to make comparisons with measurements made by other laboratories on different devices. The instrumentation and measurement conditions are probably very different.
  2. The instrumentation used for the measurements is obsolete and unprofessional. We believe that more precise instrumentation is not necessary due to the tolerances of the human auditory system. Distinguishing a distortion of 1% from one of 1.1% or 1.001% only makes sense from the electrical point of view. Probably no one can hear the difference by ear. Only a child and very few lucky people can perceive the difference between a flat response curve up to 16 KHz and one up to 20 kHz.
  3. The perception of sound depends on many factors, namely the age of the listener, the listening environment, the musical genre that is being reproduced, the listener's expectations, his or her listening habits and knowledge and many other factors, besides of course the quality of the other devices. Therefore, there is no direct and unique relationship between the results of the measurements made and the pleasantness of listening to a specific device.

Korting_Royal_Syntektor_55W

BANDWIDTH

ation caused by the loudspeakers' inductive load and the effect of the mechanical resonance of the speakers themselves on the feedback circuit are not considered. The effects are by no means negligible, the measurements carried out on a purely resistive load are
always very linear but they don't coincide with the real frequency response.

On the other hand, this response curve was measured on an inductive laod, that is, with its own loudspeakers.
The frequency response measurements were made with a sinusoidal generator and a
Wandel & Goltermann WM 20 level meter.
You can see the actual frequency response on the vobulator' screen.

Korting_Royal_Syntektor_55W

RMS POWER

We consider as Maximum Power the square of the lower of the RMS voltages measured at the three sample frequencies divided by the load resistence.
The measurement conditions are the following:
- sample frequencies, 100, 1000, 10,000 Hz
- 8 ohm resistive load
- distortion less than or equal to 1%.
The measuring instrument provides the RMS value directly.

The measured RMS power is 7.4 W

IM% at 1000 Hz

INTERMODULATION DISTORTION %

The Intermodulation Distortion % was measured with the SMPTE standard and measured at 1W RMS.
The two measurements were carried out by modulating the 50 Hz sine wave with a 1080 Hz sine wave and then with a 10400 Hz sine wave, with an amplitude in a ratio of 1/4 compared to the basic sinusoid.
The output voltage was kept around 2.83V on an 8 ohm carico.

The measured Intermodulation Distortion % (IM%) is 0.14%

LOUDSPEAKERS

The radio's loudspeakers are one of the most interesting and distintive features.

The first, as well as the biggest one, is an electromagnetic Isophon P23/25/105; its diameter is about 22 cm and with a 10500 Gauss magnet has a frequency response that goes from 65 to 10.000 Hz within +/- 3 dB.
The whole frequency range is sent to this loudspeaker and the upper part is cut mechanically.

The basses are always ready and extremely powerful. As anticipated power and dynamism are the main feature of this device.

The second loudspeaker is a 17 cm diameter broadband, with a medium cone's incline, very fast and which extens very high for a brilliant playing of mid-range sounds.
The speaker is connected to an intermediate socket of the output transformer and the latter (the last one) acts as a filter and a power redicer at the speaker ends.

Finally, we talk about the excellent electrostatic tweeter, very large and efficient with a convex front surface that increases the diffusion area.
A really well thought speakers' set, wisely implemented regardless of the price.

TONE CONTROL WITH LEVEL INDICATION

The tones control system is very efficient. Above the large tone control knobs there is a band that lights up gradually indicating the emphasis on the band on which it acts.

AERIALS

Inside the cabinet there is a dipole for FM reception and a ferrite rotating aerial for AM reception.
Ferrite aerial can be rotated from the outside to achieve a perfect tuning of the device in the AM.
In this picture you can see the rotation mechanism, and the aerial position indicator.
The reception sensitivity with internal aerials is very good. This unit was in fact produced when there were not many radio stations, and those available were far from each other.
Using an external aerial sensitivity is further increased.

Brionvega Totem RR130

BRIONVEGA RR130 - TOTEM

Brionvega is certainly the Italian brand of electronic equipment that left the deepest mark in the history of world design.
On this page, one of the most beautiful equipment of the Brionvega is presented: the TOTEM RR130.
It was designed by the architect and designer Mario Bellini in 1970.

Eight times Compasso d'Oro, Bellini counts among his most famous creations the Centro Espositivo e Congressuale di Villa Erba (Exhibition and Congress Center of Villa Erba) in Cernobbio, the Tokyo Design Center in Japan, the America Headquarters of Natuzzi in the United States, the National Gallery of Victoria in Melbourne, the Headquarters of the Deutsche Bank in Frankfurt, the Department of Islamic Arts at the Louvre in Paris, the new Convention Center in Milan.

The Brionvega Totem, along with others of Bellini's works, is exhibited at the MOMA in New York. It is visible on this page of the museum.

When closed it looks like a smooth cube of 51 cm per side.
Once opened, the turntable, the console and the two adjustable and removable speakers are found.
The turntable is a beautiful DUAL 1257 with a magnetic cartridge DUAL DN145E. The turntable and the cartridge will be analysed in detail later.
The central body includes a 22W stereo amplifier, an AM/FM tuner and a muzak receiver.

The Totem project follows the famous RR126 Radiofonografo. The two devices share different circuits, but several improvements and updates have been implemented in the Totem.

The acoustic quality is interesting. Leaving the speakers in their rotating supports, the distance between them is sufficient to guarantee a fair stereo separation, even if the best results are surely obtained by extracting the speakers from their supports and placing them at a distance of more than 1,5 meters.
The power is more than enough to fill medium-sized environments.
Rather than the frequency response, which is still quite linear, the most interesting feature is the kind of musicality the device can express. In fact, the sound is warm and mellow, close to the sound of tube amplifiers. This result derives from the type of circuit with a low negative feedback rate and the use of fair components, in complete contrast to the projects of Japanese derivation that were so fashionable in the 1970s.

A musicality with these features, a brilliant design, such a strong personality have determined its remarkable commercial success.

In our restorations we propose a small modification to the loudspeakers by equipping them with a brighter tweeter, which associated with the insertion of a bluetooth 5.1 circuit or of a wi-fi connection allows the listening of liquid music or any web-station of the world with a satisfying level of pleasantness in the listening.

The aesthetic remains absolutely unaltered but the sound changes significantly, becoming considerably more precise and free of disturbances.

Almost all the devices that are sent to us are stained, yellowed and with damaged edges.
For this reason we have equipped ourselves for the total double repainting (white and anthracite) and the screen printing of all the front and back writings.

These incredible restorations are photographically documented at the bottom of the page in the dedicated section.

HISTORY

In 1945 in Milan, Giuseppe Brion and the engineer Leone Pajetta founded the B.P.M. (Brion Pajetta Milano), electronic component production company.
At the beginning of the 50s the company specialized in the production of radio devices and becomes the Vega B.P. Radio.
At the beginning of the 60s specialized in the production of Tvs and becomes Radio Vega Television.
In 1963, the company takes the definitive name of Brionvega.

Brionvega since ever had world-known designers and produced objects that are exposed in the most famous international museums.
Among the firsts designers Zanuso and Sapper, 1964, that projected the portable TV Algol 11 (picture on the bottom left) and the radio TS 502, the “cube” (picutre on the bottom right).
In 1965 the Castiglioni brothers (ppicture on the top left) signed then the Stereophonic Radiofonografo RR126.
In 1970 the designer Mario Bellini traces the shape of the stereo system “Totem” (picture on the top right).
In 1992, the company is sold by the Brion family to the Seleco.
In 1997 Seleco goes out of business and Brionvega, controlled, does so.
In 2004 SIM2 Multimedia has acquired the part of the Brionvega company dedicated to the radio production.
In 2010 SIM2 Multimedia acquires also the TV sector of the historical italian brand.

TURNTABLE

The turntable used in the Totem is the DUAL 1257.
This is an excellent semi-automatic equipped with a DUAL 16-pole motor, with belt transmission and a very heavy plate, for an excellent rotation stability; wow and flutter, in fact, remain within a small 0,05%.
The belt transmission and the detachment of all the not necessary mechanisms during operation allow to reach a signal / noise ratio of 68dB.
The 1257 is equipped with stroboscope and fine adjustment of the speed. It is also provided with micrometric adjustment of the bracket weight and separate Antiskating settings for Conical or Elliptical stylus.

The magnetic cartridge is a DUAL DN145E. This is a cartridge with diamond elliptical stylus built by Ortofon.
A frequency response is declared from 10Hz to 28,000Hz with an output level of 4.0mV
The dimensions of the elliptical stylus are 6 x 18 μm.
The manufacturer recommends adjusting the weight to 1,5 gr.
The load resistance is 47 kOhm.

Brionvega Totem RR130 Brionvega Totem RR130

VOLUME CONTROLS

The Totem RR130 is equipped with two separate volume controls.
- The first (LOUDNESS) changes the level by automatically changing the frequency response curve according to a physiological criterion (at low volume the bass and treble are enhanced).
- The second (VOLUME) changes the level, leaving the frequency response curve unchanged.
Both commands increase the overall output level.

Listening to LOW LEVEL: turn the volume knob to maximum and act only on the loudness knob to get the desired level.
Listening to MEDIUM LEVEL: turn the volume knob halfway and turn the loudness knob to get the desired level.
Listening to HIGH LEVEL: act on both the volume and loudness knobs to get the desired level.

CONTROL PANEL

 Left from the top we find two instruments:
- the FM signal level
- the centering of the station
Then we find the knobs of LOUNDNESS,  LEVEL, BALANCE, TREBLE and BASS.
Below we see the knob of the AM tuning which acts on the indicator of the three scales below SW, MW, LW.
On the right you can still see the FM tuning knob which acts on the scale up indicator, FM.

Brionvega Totem RR130

In the lower row of the panel we find a series of keys that have the following functions:
ON/OFF
AFC - Automatic Frequency Control
PHONO - Turntable
TAPE - Tape Recorder
FD - Muzak
LW - Long Waves
MW - Medium Waves
SW - Shortwave
FM
Finally we find six keys numbered from 1 to 6 with which you can choose the channels of the muzak.

LOUDSPEAKERS

Each speaker is equipped with three cone speakers, a woofer, a midrange and a tweeter.

Curious is the electrical connections between loudspeakers and amplifier. It is obtained simply by inserting the loudspeakers box into the appropriate support tube, equipped with slide contacts.

The woofer and the mid are quite adequate to the characteristics of the amplifier.
The tweeter is a little silky, soft, it lacks a bit in transparency in the higher frequencies.
This feature was totally irrelevant in radio reproduction, while using the Totem for listening to liquid music or other digital sources we prefer to replace the tweeter with a more modern and brilliant one.
Also the reproduction of vinyls benefits considerably from this.
Of course, in our restorations, the modification leaves the external aesthetics completely unchanged.

PHILIPS CAPELLA 753/4E/3D

PHILIPS CAPELLA 753/4E/3D

The Philips Capella 753/4E/3D was the company’s flagship model back in 1955, but in reality, the brand was working towards making it the best piece of technology to come out of Germany, blowing away the competition.

As a matter of fact, they met their goal and produced a unique piece of technology, for both the German and World Wide market.
It’s peculiarities are:

  • A motorized Tuning
  • 6 memorizable stations
  • 4 power tubes (2xEL84 and 2xUL84)
  • Dedicated amps for Hi and Low frequencies
  • An Iron-Free coupling output (OTL)
  • High Damping Factor with Negative Feedback circuit
  • 4 High impedance speakers

Even though the Philips Capella 753/4E/3D boasts a noticeable size, it’s woodwork, frames, and speaker covers contribute in giving it a much sleeker, eye-pleasing look to complete any furniture display.
The Low frequencies are particularly deep thanks to the separated OTL amplifiers and to the impressive size of the subwoofer, approximately 26cm in diameter (more or less 30 inches).
I suggest making good use of the mid-tweeter, as this successfully crafted speaker (17 cm in diameter) makes the mid and Hi frequencies pleasant and true to life, especially if seated in front of the Machine.

High and Mid Frequencies sections
The FM group is of the variable permeability type.
It has a high amplification and stability. Being equipped with an automatic noise suppressor in the presence of signals below 1.7 V, the output is muted to avoid hearing rustling and noise when searching for stations.
The de-emphasis circuit is set to 50 uS, valid all over the world except for the USA and South Korea. In these countries, the filter should be increased to 75 uS.

The AM section is equipped with a rotating antenna for the OM and OL bands. The antenna can be controlled by a knob on the front.
The mid-frequency sections are composed of three separate filters for AM and FM. The first of these filters is adjustable. The second is the amplifier filter and the third filter further increases the selectivity of the device.

The Motorized Tuning and the amplifier section are examined in detail in the following sections.

All the listed solutions translate into a very low distortion, an increase in power, and a pleasantness of use hardly ever obtained in other appliances.
This is the Philips Capella 753/4E/3D

HISTORY

In 1891, the brothers Gerard and Anton Philips, started to produce the first incandescent bulbs in Eindhoven.
Later, Philips specialized in the production of electro- medical equipment, and in 1918 introduced the first X-ray tube.
In the following years, Philips began specializing in the broadcasting industry. In 1932 the company succeeded in selling over one million radio equipment and became the world’s first producer.
During the Second World War, Philips transferred to the Netherlands Antilles, and returned to the Netherlands at the end of the conflict.
In the second post- war period, began the production of the first televisions, then the launch of the music cassettes in 1963 and the production of the first integrated circuit in 1965.
In 1982 Philips launched with Sony the first compact disc player.
In 1984 Philips acquired the control of the German Grundig.
In the 90's Philips faced a financial crisis.
In 1991 it inserted on the market the Video CD and it is one of the first companies in the world to develop high definition television.
In 1999 Philips established a joint venture with LG Electronics, named LG Display, which ends in 2009.
In 2006 together with Sony launched the first Blu-ray.
In 2009 Phillips launched the first full-HD LCD TV in 21:9 format.
Phillips holds 48,000 registered patents.
Currently, the production is focused on low- energy lighting products and LED systems and services for diagnostics and production of medical devices.

AMPLIFIERS

The preamplifier consists of two stages. At the entrance, the volume potentiometer is equipped with three sockets for physiological correction (loudness). The intervention curves are visible in the first graph.
Philips considers the frequency of 800 Hz to be the center of the audible band, so the treble and bass controls are calculated to enhance the frequencies above and below that value. The choice of this frequency is very important for the musicality and the pleasantness perceived by listening to the device.
In the second graph the frequency response of the preamplifier, with the tones enhanced to the maximum. You notice the different equalization you get by listening to the AM bands (Long Waves, Medium, Short) or listening to the FM band and PHONO.

The final stages are two distinct, one for the low frequencies and one for the high frequencies. These amplifiers control separate speakers, a 26 cm woofer for the bass and three speakers for mid/high frequency, with the 17 cm front speaker disconnectable for 3D effect.
The most interesting feature of these final stages is that they are without an output transformer.

The feature that makes this device very interesting is that each final stage uses a pair of EL84 / UL84 in an ironless configuration, ie without an output transformer (the known critical point of the final stage).
The output stage uses the operating principle called Shunt Regulated Push-Pull (SRPP) used today in HIGH-END amplifiers.
The output transformer limits the bandwidth of the entire amplifier. The bass is limited by the inductance of the primary winding, the treble is limited by the parasitic capacitance resulting from the alternation of the primary and secondary windings. The alternating winding of the primary and the secondary windings is also necessary to improve the coupling and thus reduce the dispersed flow.
The reduction of the dispersed flow increases the damping. This is essential in the loudspeakers mounted inside the cabinet of the radios, which do not work in hermetically closed boxes, and which are therefore free to move almost without resistance from the surrounding air.

The two output tubes (EL84, UL84) of each channel, four final valves in total, are connected in series with DC-DC coupling. Each UL84 is configured as a triode.
The output is taken from the cathode of the UL84. The speaker has an impedance of 800 ohms, identical to the average impedance that occurs on the catode, whereby direct coupling (without transformer) is possible between the final stage and the loudspeaker.
The Philips Capella 753 is therefore totally free of all the problems deriving from the output transformers.

The damping of the loudspeakers is kept high by the low dynamic resistance of the feedback loop.

 

MOTORIZED TUNING AND PRESET MEMORY

Another feature of the Philips Capella 753/4E/3D is motorized tuning and preset memory.
Using 6 keys on the keyboard it is possible to memorize 3 FM stations, 2 in Medium Waves and 1 in Long Waves.
Pressing one of the storage keys via a cable pulls the lever H. The opposite side of that lever is pushed towards the disk R. This disk is divided into two parts with different diameters. Depending on how the disc is positioned, the lever H moves by activating a switch that turns the motor to the right or left until the lever H is fitted on the groove on the disc R. At this point, the motor stops. The R disks are rigidly connected to the axis A1 and through frictions to the R disk.

Tuning procedure

When a memory key is pressed, the motor will start to turn to the right or left according to the above.
Through the gears, Z1, Z2, Z4, Z5 the axis A1 is turned. Through the gears, Z6, Z7 the variable capacitor is rotated, which stops when the lever H engages in the groove of R.
To memorize a station, simply press the button on which it is to be stored, pull the tuning knob and turn it to the desired station.

TONE CONTROL WITH LEVEL INDICATION

The tones control system is very efficient.
Above the large tone control knobs there is two bands that lights up gradually indicating the emphasis on the band on which it acts.
The high-tone control knob is linked to two thin ropes. One of them is for the position indicator of the control itself, whereas the other changes the position of the ferrite in the MF transformers modifying the its curve.
By doing so high tones were attenuated/accentuated even before getting to the BF stage.

ANTENNE

Inside the cabinet there is a dipole for FM reception and a ferrite rotating aerial for AM reception.
Ferrite aerial can be rotated from the outside to achieve a perfect tuning of the device in the AM.
In this picture see the rotation mechanism and the position indicator of the aerial.
The reception sensitivity with internal aerials is very good. 
Using an external aerial sensitivity is further increased.

TUNING INDICATOR

The magic eye has of course been replaced.

LOUDSPEAKERS

The 28 cm loudspeaker, with a 25 mm diameter magnetic core, is placed at the front.
A front 17 cm mid-tweeter can also be switched off if you want to increase the 3D effect.
On the two sides, there are two elliptical tweeters pointing upwards. Radiating to the ceiling of the room to take advantage of the reflections of the environment that add to the direct radiation produce an expansion of the soundstage.
There are no dangers of stationary wave due to the working frequency of these speakers.

There are several options for connecting external speakers.
It is, in fact, possible to connect an external woofer, excluding or not the internal woofer while leaving all the other speakers active.
It is possible to connect external medium-high units, excluding or not the internal mid-tweeters, while leaving the internal woofer active.
It is possible to connect woofers and external medium-high units, excluding or not all, or some, internal speakers.

CONTROL PANEL

Philips Capella 753/4E/3D

In the center of the speaker panel is the Magic Eye which indicates the perfect tuning of each station.
KLANGREGLER - Low Tone Indicator (FA Key) and High Tone Indicator (SOL Key).
Just below we find the large Volume knob, with built-in automatic loudness correction.
Coaxially you can see the 3 position Speaker Selector Lever (External Only - Indoor + Outdoor - Indoor Only)
Below we find the two coaxial knobs arranged horizontally, which respectively command the Bass Tones and the Treble Tones.
In the middle, we see the dial scale of the AM bands on a dark background (Long Waves - Medium - Short) and the dial scale of the FM band on a golden background.
FERROCEPTOR - Indicator of the position of the internal ferrite antenna. This internal antenna (excludable with the HA key) is used in the OM and OL bands. The internal antenna must be rotated until the best tuning is achieved.
Just below we find the large knob of the Manual Tuning, whose movement is very pleasant being supported by a large flywheel.
ZEIGER - Coaxially you can see the drive lever of the Motorized Tuning. It can be moved in the two directions, to the left or to the right.
Finally, underneath again we find the Rotation knob of the Ferrite Antenna.

To store a station you must:
1 - press the desired memory key.
2 - Pull the tuning knob and tune to your favorite station.
3 - Release the tuning knob.


Under the dials, we meet a long series of 14 keys.
Starting from the left the keys have the following functions:
OL memory
OM1 memory
OM2 memory
AUS - Switch off
3D - Excludes Mid / Front Tweeter by increasing the three-dimensional effect of the sound
HA - Outdoor / Indoor Antenna for OM and OL

KÖRTING NECKERMANN STEREO STEUERGERÄT 821/80

Korting Neckermann Stereo Steuergerät 821/80 has an elegant line and its compact dimensions in relation with other sinto amplifier of that period make this machine easily placeable in modern and minimalistc environments.

Its the most prestigious device produced by Körting-Neckermann in those years. Körting became famous for its excellent (and expensive) TVs and then the company had been absorbed, like many other german companies, by foreign assets, in this case Slovenian to produce various electronic devices.

The use of this machine is very simple, being it intentionally not equipped of filters compensations automations or others. A few but very efficient controls: treble, bass, volume, balance and obviously the tuning changes.
In particular, the tone control (Baxandall) is extremely efficient. It is the same kind of control still used nowadays in the high fidelity amplifiers.

Korting-Neckermann 821-80

The balance has been obtained with a particular circuital solution, the control indeed has been placed after the output transformer. You get a balance control that can be very precisely calibrated. However, even turning the knob all on one side, the channel never reaches the Zero.

TUBESOUND ENHANCEMENT

- Separate loudspeakers - Using separate loudspeakers is an important option for stereo receivers. This allows you to couple the receiver to speakers best suited to particular space, design or acoustic performance requirements. The most suitable loudspeakers are analysed later, under loudspeakers.

- Stereo Decoder - The device has an integrated Stereo Decoder. This allows you to listen to stations that use this transmissions system in stereo. Many stereo receivers are not equipped with a Multiplexer so they work in stereo only when you select the record player’s /Recorder/Aux input . Such receivers, in listening to the radio, send the same signal to both channels, so listening is monaural. This is not the case with the Concertino 2380, which is totally beyond stereo.

- Built-in Bluetooth receiver - This unit can be equipped with a BLUETOOTH receiver powered directly from the device. That makes it possible to use the amplifier from any digital device, IPAD, Smartphone, or sophisticated multimedia station. You can listen to your wireless Web Stations or favorite music around the room. On request, we can also mount a Wireless Receiver.

- Multi Platform connections - Along with the device, we can also provides you an impedance adapter cable to connect any digital source, such as iphone, smartphone, computer, CD player, etc. This purpose-built cable adapts different impedances of modern digital equipment. Also the two stereo channels are collected into a single flow without increasing the load input unit.

Inside the Cabinet there is a dipole to receive FM bands and Shortwaves.

A ferrite antenna is for long and medium waves reception.

Using the internal antennas, the sensitivity is very good. Of course, under some conditions, using an external antenna further increases the receiver’s sensitivity.

SEPARATED TUNING CONTROL BETWEEN AM AND FM

The tuning system is interesting and different than other devices made in Germany. The device is equipped with separate tuning mechanisms for AM and FM bands.
There are two tuning knobs, separate but coaxial, with cable and pulley systems separated depending on the band.
This type of tuning has a very strong mechanics. Regarding maintenance, cleaning and lubricating once every 10 to 15 years is sufficient.

BRAUN建造的最佳电子管接收器
Same receiver you find on model with turntable Atelier 2 and 3.

但让我们从头开始。接收器部分可以说是Braun电子管设备生产的极限。德国最大的电子管接收器生产还是属于这些大厂,比如Telefunken Opus 2550,Nordmende 3004,Graetz Stereo Unit 250,the Saba Studio I等。

本装置的主要特点是电路的简化(现今而言是理所当然的,但1961年被认为是一个显着的特点)。Braun不同于其他设备,针对低失真和杰出的音乐透明度其负反馈减少到单一的电阻(图中红色圈记)。

权威的声音控制电路:一个非常有效的且平衡的Baxandall电路(图中黄色圈记)。它允许依据电位器而不改变信号的相位状况下控制声音。

响度电路(图中绿色圈记)是非常简单的而且低频重点研究是正确的。声音质量和德律风根,Nordmende是一样好;和GrundigGraetz在同一水平,Braun也许比他們更细致。

你肯定需要一組高效率的扬声器。其惊人的设计和其性能对这种升级的设备是有价值的。

 

-调频频率范围扩大到88~104兆赫。
-配备超静音MPX解码器。
-具备静音电阻器的输出级。
-配备蓝牙接收器。
这是一部配备齐全的电子管接收器

放大管声音的改进

- FM频率范围从88到104兆赫---在1950 / 60年代德国生产的电子管收音机是世界闻名的,这是因为他们出色的声音质量,他们美丽的机箱外型,他们的实力和他们没有妥协的作业标准。不幸的是,FM频段只有从87.5~100兆赫,但无法接收到100兆赫以上的电台,经过仔细的研究和大量的测试,我们能够获得的频率范围由原有范围扩大至88~104兆赫。我们还重建了一个与原始完全相同的玻璃面板,用相同的材料和相同的技术,且与新的频率范围对应,结果是完美的。使我们可以在任何国家收听到大部分的FM电台。

相容性特点:
-比Braun稍新几年
-与原来的唱片机尺寸相当
-Piezo唱头: 所以它能夠在Braun前置放大器完美地工作
改进特点:
- 唱头重量调整
- 抗滑调整
这是必要的一个重要的上方面板调整工作,但结果是完美的,似乎是与生俱来的。

- - 放大器的改进---新的高品质金属膜电阻器取代嘈杂的老式碳复合电阻。旧的电容器完全更新,新的电阻器具有非常低的寄生损耗(ESR)。我们非常注意这些老旧零配件的续用性。所有的改进都是实质性的。

- -超静音MPX解码器--- MPX解码器引入RF和BF阶段之间。通常没有这个装置的。这个解码器是由和我一起工作德国工程师特别为这个接收器设计的。噪音电平非常低。串话干扰完美校准。正确的接收条件,结果是一个准确的声学重建

- 蓝牙接收器加装-该单位配备了一个蓝牙接收器,直接由收音机供应电源。这使得有可能控制放大器从任何外部数字设备作为一个iPad,智能手机,或一个复杂的多媒体站。所以你能无线听到您喜欢的网站或你的无损档案。无线接收器可根据要求选配。

包豪斯与60年代

 

 

1961年是“第二十世纪历史”的“十字路口”之一。在欧洲,这一年的事件将留下深刻的印记,无论是好是坏。战后的国际形势发生了深刻的变化。那些打败纳粹德国的国家现在在军事上和思想上都是对立的。从年初起,冷战影响了全世界,新的全球战争的威胁出现在这一点上不可避免的。在这种阴郁的气候下,人类接连发生了一系列重大事件。

特别是在德国,1961年被回忆起“长城之年”。几天后,德意志民主共和国当局下令建造一个双层墙和武装监视系统,目的是阻止民主德国(含首都东柏林)和德意志联邦共和国(简称“联邦德国”或“西德”)所属的西柏林之间人员的自由往来。柏林墙成为东西柏林地区之间的对比,逐渐涉及到整个世界的象征,不久之后将在两年后与古巴危机的核灾难的边缘。

对比两个超级大国涉及经济和政治生活的各个领域。科学研究为征服太空而铺路,也开辟了美国与苏联之间的另一场太空竞赛。1961年4月12日,Yuri Gagarin与东方1号是第一次人类在太空轨道环绕地球的。美利坚合众国必须承认这是苏联技术发展的巨大飞跃。

这是以对立身份出现知识分子之间建立的桥梁。对文化而言1961年果然也是不平凡的一年:Ivo Andric是获得诺贝尔文学奖;法兰克福学派实证主义与辩证唯物主义之间的争论。Karl Popper和Theodor Adorno讨论了科学的研究方法,产生了“Positivismusstreit”,即实证主义和唯物辩证法之间的冲突,将影响未来的认识论的争论。哲学论争是由马克思主义和实证主义的不同意识形态观所引发的。海明威自杀,Primo Levi写道“休止/停战”,历经啤酒的地狱后回到生活世界的帐单。

此外,已在第二次世界大战中被摧毁,在50年代继续形成了一个前所未有的经济增长时期的铺垫,1961年经济繁荣年和重新建设的欧洲。福利社会兴起,德国处于第一线。

德国文化的重新发现者Weimar。而艺术和戏剧的先锋派的代表,如Brecht. Walter Gropius.在1919的包豪斯建筑的革命倾向的创始人,Walter Gropius是BAUHAUS学校的创办人,包豪斯的目的是将艺术和工艺结合起来,以此解决工业革命所产生的问题。Walter Gropius认为,“必须形成一个新的设计学派来影响本国的工业界”。第二次世界大战后,他的建筑理论和实践为各国建筑界所推崇。他认为现代建筑师要创造自己的美学章法,“通过精确的不含糊的形式,清新的对比,各种部件之间的秩序,形体和色彩的匀称与统一来创造自己的美学章法。这是社会的力量与经济所需要的。在日常生活用品的设计中,包豪斯强调设计家要着眼于工业大生产,要为大多数人生产实用美观的物品,而不是为少数的富豪生产奢侈品。

新的建筑技术的概念进入大公司槽由聘请设计师,新的专业,开始影响生产线。随着事情的新方法,是产品的销售对象是在一个“总”的产品来看,这是一个综合的技术和概念,现代的设计理念为我们目前的意思是天生的。

Braun是最早决定投资设计的公司之一。最好的设计师是Dieter Rams,他出生于1932年5月20日,出生地是德国的威斯巴登。1947年他在威斯巴登的Werkkunst学校建筑学专业学习。1955年他成为1921年建立的Braun公司的一位建筑师和室内设计师,1956年开始为他们设计产品。1961年他成为布劳恩公司产品设计和发展部门的领导。他曾为建筑师奥图·阿培尔(Otto Apel)短暂地工作,随后便加入家电用品制造商百灵的设计部门,同时期建立起与乌尔姆造型学院的产学合作关系,1961年晋升为百灵首席设计师,一直到1995年仍留有这个头衔。他带来了发展“符合人体工程学的重要性”的概念,总结了他的名言"Weniger, aber besser",,即“少,但更好”,或者更广泛意义上的“少,只要更好”。他在作品中对Bauhaus的影响是明显的,特别是Peter Keler的作品,从他作为概念的“空间”和“线性”的作品为“wiege(摇篮)”,1922翻译成简单和优雅的线条。

Dieter Rams Paris.jpg

Dieter Rams at Vitsœ - Paris

由Dieter Rams提出,好的设计应具备的十项原则:

1.好的设计是革新的: 永远不要为了设计革新而革新。

2.好的设计是实用的: 产品是供人使用的,好的设计强调产品的实用性。

3.好的设计是美观的: 一个产品的审美品质和它的实用性是不可分割的,因为产品每天都在使用,对人们和他们的幸福都有影响。

4. 好的设计使产品可以理解: 它能够自己解释自己。

5.好的设计是谨慎克制的: 履行某种功能的产品具有工具属性,它们既不是装饰物也不是艺术品。

6.好的设计是诚实的: 产品不应该看起来比实际上更创新、更高效和更有价值,它不试图通过无法兑现的承诺来操纵消费者。

7.好的设计是经久永恒的: 它避免迎合时尚,也因此不会过时。

8.好的设计在细枝末节处也维持一致: 不要容忍随意和偶然。设计的逻辑性和准确性,最终都是表达对消费者的尊重。

9.好的设计是环保的:设计是要为保护环境作出重要贡献。

10.好的设计是尽可能少的设计: 少,但更好。回到纯净,回到简单。

Ducati RR…

Ducati RR3404 Paniere

The Ducati Breveti Society was born in Bologna in 1926 by the Ducati family.
The business grew quickly, so much so, that Adriano Ducati decided to extend the production from condenser to complete radio equipment.
When the Borgo Panigale office was opened further expansion took place.
In 1938, the Optics centre was created and for this reason two other plants were built near Borgo Panigale (one near Bazzano and one in Crespellano).
This production intensified to the point that Bruno Ducati began to study a new project to extend the plant even further.
In 1935, the Borgo Panigale plant was established.
This was a modern and ambitious project intended to create an industrial and technological centre in Bologna.
During this time, Ducati developed abroad opening branches in London, Paris, New York, Sydney and Caracus.
In 1954, during state management Ducati’s production was divided into Ducati Electrotechnics and Ducati Mechanics.
Ducati Mechanics was located in Plant 2, while Ducati Electrotechnics (now Ducati Energia) occupied the rest of the building.
The rest is modern history.

It is not a device purchased in recent times. It was purchased from the grandfather of the current owner.
The radio remained in the family, it was the only survivor of a previous collection; it was too important to remain abandoned in a damp warehouse.
This magic talking box, deserved to see the light of day again and make its baritone tone resonate in the middle of the room.

The page dedicated to this device is different from the usual one, it illustrates the history about this excellent and fascinating restoration.

我曾用这句话来描述Saba Freiburg 100:最伟大的使命就是超越自己。然而,这个故事还在继续中。Saba Freiburg 14是由Freiburg 100,125,11和12进化而生。Saba Freiburg 14可说是完美终极的机型。其次可与之匹敌的只有Freiburg 18(它有一个椭圆形的高音喇叭代替两圆形高音喇叭,以木制窗格带代替帆布---但这种审美的选择不是每个人都欣赏)。
Saba继承德国的传统,尽管后来的產品与原来的杰作没有什么共同点,Saba还是继续在顶级机型使用Freiburg这个名称。
我想强调的是,这是在德国科技和生产的黄金时代里,德国最负盛名品牌的顶级机型。
正如我前面提到的,第一次视觉冲击是令人震惊和激动人心的。这是一个大型收音机成功地炫耀它的雄伟。

历史

SABA是德文Schawarzwälder-Apparate-Bau-Anstalt的缩写,也就是黑森林技术设备工程学院。

公司在1835年由Joseph Benedikt成立,最初的公司名称是Jockele-Uhren,但只有1923年起的无线电设备生产开始,公司才以SABA的名义。
在20世纪末,SABA因制造S35而闻名.和在随后的几年,它仅次于TELEFUNKEN成为德国第二制造厂。战争期间,SABA生产军事装备并于1945年公司被彻底炸毁了。
1947年SABA是以收音机制造东山再起,和之前不同的是,现在是前卫和高质量的生产

他们也开始生产电视机(第一台PAL彩色电视就是SABA所生产),家用电器和医疗设备。许多意大利人曾经在那里工作。Alnico Greencone扬声器的高线性,高功率容量,恒定阻抗而成为流行.当时每一Hi-Fi音响设备都采用。

收音机电动调谐成为流行,同时SABA因其高质量、可靠性和精密度成为德国代表品牌。1970年代衰落开始。根据当时的专业杂志报导,如果你未拥有日本收音机,就表示你未曾拥有Hi-Fi。在上世纪80年代,Thompson(汤普森)接手SABA。在90年代,相反的,如果你拥有日本收音机,就表示你未曾拥有Hi-Fi。他们发现他们有96%逆反应,即便设备从1到100千赫只有0.001分贝的延伸也不一定是好声音。

即便没有好的目的,我们总会不相信自己的耳朵,而是相信别人所说的。

2007年:自从TLC(中国)和汤普森(法国)合资经营后,SABA因财务困难而不复存在。

音调控制

音调控制系统是非常有效的,在音调控制旋钮上,你可以找到一个小窗口,逐渐显示出对乐队的重点。

BANDBREITE SCHALTBAR

这个频率反应校正系统是由一个MUSIK/SPRACHE按钮组成。
在听口语或音乐节目时,这个校正系统会给出合适的高低声调。并有指示选择的灯号。

天线

机壳内有一个半波偶极天线FM调频接收和旋转镍锌铁氧体天线AM调幅接收。
旋转镍锌铁氧体天线可以从外部旋转,实现了在AM调幅完美的调整。
在这张图片中,看到旋转机构和空中的位置指示器。具有内部天线的接收灵敏度很好。
生產这收音機的那年代,那時的廣播电台是寥寥可數的。
使用外部天线会使接收灵敏度进一步增加。

AM调幅和FM调频是各自控制调谐

调谐系统是另一个特点
该单元配备了保持独立的AM调幅和FM调频带的机制。
调谐钮是单一的,但有一个选择器开关通到电缆系统(全不锈钢)和滑轮分离。
这转动是伴随着两个复杂的滑轮和分离齿轮的转移机制

调谐指示器

调谐指示和立体声接收指示的磁眼都是新的。

电动遥控器调谐

调谐系统是一项杰作。
它是由一些电容器移相的绕组所提供的电动机。它可根据是否搜寻到电台而允许改变电机的旋转方向。
调谐中心点是由CAC电路和一电子管继电器的信号共同控制。
正如已经提到的,是相当复杂的,如果没有Saba原始使用手册是无法执行校准的。
下面详细说明引擎和模式控制的自动化。

音量控制

另一个有趣的功能是音量控制。
旋钮不自动控制音量电位器。它通过活动的推拨钮控制。
电动遥控器有轻微的摩擦效果,加强旋钮转动时的阻力。

遥控装置

另一个独特的功能是在收音机背面于指定插座(见图片),

插入电动遥控器插头遥控音量和调谐。

照亮键盘

另一个显着特点是照亮键盘。

点亮所选按钮。

小灯泡非常稀有,很难找到。

单声道/立体声开关

单/立体声换向器也有灯光指示
通常只有当你听CD或iPod立体声才会工作,但该机型配备了立体声解码器,提供一个准确的立体声FM收音。

右边的魔眼可显示已收到的电台立体声调制强度指标。
上图显示了立体声电台的接收。

扬声器

扬声器是这台收音机的另一个显着的特征:著名的Alnico Greencone。
它的侧宽带创建一个3D效果。
在立体声和四声道到来之前,该主题已被广泛的研究。
听觉效果是非常惊人的

控制面板
