In this review we analyze two very similar devices, the Philips Capella Reverbeo B7X14A and the Philips Capella Reverbeo B7X43A.
The two models are completely identical except for the fact that the B7X43A has a stereo decoder, while the B7X14A does not.
With the B7X14A, therefore, FM stereo transmissions are received in mono.
The front differs due to the presence of the stereo indicator in the B7X43A.
Both models are equipped with two Class A final stages, with an EL84 for each channel. Therefore, with both, stereo listening is provided when the source is a turntable, a tape recorder, a CD player or Bluetooth.

The most important feature on both models is the presence of the electro-mechanical reverb circuit, which can of course be excluded by a button on the front. The Philips reverb will be analyzed in detail below.
These two top-class Philips devices are the only German-made radios equipped with reverb. Saba, Grundig and Philips included reverb as an option on some rare top models of their large radio cabinets, but no classic radio was equipped with reverb.
The effect of reverb is very pleasant especially in sacred music, choirs and chamber music. In rock and jazz music, however, it generates excessive confusion in my opinion and it is preferable to exclude it with the appropriate button.

When you insert the reverb, the two channels are automatically connected and the playback becomes monophonic.
One last warning, pressing the HI-FI or SPRACHE buttons inserts equalizations set by the manufacturer, which are not configurable, and the Bass and Treble knobs no longer have any effect.

The presence of reverb, the double cone speakers arranged at an angle and the futuristic line for the time make it one of the most appreciated and sought-after devices of the Philips production of the time.

The first track is a Reveberation Example. This is a recording of any FM broadcast where you want to hear the reverb effect. The recording starts with the reverb on, then you hear a "Stack!" and the reverb is turned off, then turned on again and so on. This way you can appreciate the level of reverb that Philips has planned for this device. In fact, although it is clearly a distortion of the sound, it is very interesting, the songs seem to come from inside a large room, or a church, and the effect is incredibly pleasant.

The second track performed by Abdullah Ibrahim is called Cape Town to Congo Square 1. Adolph Johannes Brand (Abdullah Ibrahim) is a South African pianist and composer. His music often draws inspiration from the music he listened to in his childhood in the multicultural port areas of Cape Town, ranging from traditional African songs to church gospel, Indian ragas, and more modern jazz. She manages to blend American jazz, Duke Ellington's big band compositions with the revolutionary innovations of Ornette Coleman and the avant-garde of the 60s.

The third song is performed by Ella Ronen & Sam Cohen, it is called I just want to see you. It is part of the album “The Girl With No Skin”. A very interesting project where the singer, poet and activist addresses the burning issue of being a woman today, with all the conflicts and contradictions, the rediscovered strength and weakness. "I just want to see you" talks about the couple and the difficulties of being yourself and being a couple when instead we are continuously encouraged to play roles. A very sweet song that gives energy and hope. "I don’t want to be your mother / I don’t want to be your muse / I don’t want to take your freedom / I don’t want to make you choose / I just want to see you"

The fourth song performed by Buena Vista Social Club is the famous Amor de loca juventud. (Love of the Crazy Youth) written and composed by Rafael Ortiz in the 30s is a song with influences from black music from the neighboring United States, very popular in Havana in those years. Buena Vista Social Club was the name of a club in Havana (Cuba), whose entrance was reserved for people of color. Almost forty years after the club closed, a group of Cuban musicians merged into the Afro-Cuban All Stars. The Californian guitarist Ry Cooder also participated in the initiative. The album Buena Vista Social Club was released in 1996. In 1999, Wim Wenders directed a documentary about the entire story of the production and the members of the orchestra, also entitled Buena Vista Social Club.

The fifth song performed by Francis Poulenc is his Stabat Mater Dolorosa. In late 1950 Francis Poulenc began writing the Stabat Mater, FP148 for soprano solo, mixed choir and orchestra dedicated to the memory of the stage designer Christian Bérard, a dear friend of Poulenc, who had died the previous year. s Poulenc had shared with Bérard the experience of rediscovering his faith after going on a pilgrimage to the Sanctuary of Rocamadour. This is one of Ozawa's historic Boston recordings. The pure and crystalline voice of the American soprano Kathleen Battle marries perfectly with Poulenc's sacred pieces. The Stabat Mater "Stava la madre" is a Catholic sequence from 1200 attributed to Jacopone da Todi. The first part of the sequence begins with the words Stabat Mater dolorósa and is a meditation on the sufferings of Mary, mother of Jesus, during the Passion and crucifixion of Christ.

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.

This type of reverb was developed by Bell Labs in the 30s for the organs of Laurens Hammond to obtain a spatial effect that aimed to replicate the natural reverb of a church even in the small rooms of a house. In the 60s and later they were used in the amplifiers for musical instruments of all the most famous manufacturers, Fender, Vox, Marshall and others.

The mechanical part of the spring reverb is composed of three fundamental elements, the Input and Output Transducers, the Transmission Springs and the Suspension Springs. Essentially the audio signal is sent to the piezoelectric transducer located at one end of the transmission spring, the vibrations reach the transducer located at the other end of the springs after being subjected to oscillations, reflections and delays. The output of the transducer is sent mixed with the direct sound source to create the final output signal.

PHILIPS decided to implement this incredible mechanism in its most prestigious devices, the CAPELLA REVERBEO B7X43A and B7X14A.
The reverb units used by Philips are of the double spring type, which unlike the triple spring type return a more evanescent and characteristic sound, not obtainable with digital convolution reverb algorithms.
A button on the front allows you to insert/disinsert the reverb circuit. Inserting the reverb automatically switches the channels to monophonic. Listening to both music and speech with the reverb inserted is a fascinating and fun experience.

The speakers used on both channels are the very special AD3800AM.
These are 20 cm bicone speakers with an impedance of 800 ohms.
The frequency response extends from 70 to 18000 Hz, and they are equipped with a 9500 Gauss magnet.
The speakers are mounted facing the front corners in order to accentuate the stereophonic effect when the listener is positioned at least one meter away from the radio.

There are several options for connecting external speakers. Naturally, any external speakers must also have an impedance of 800 ohms.
It is possible to connect external speakers, excluding or not the internal speakers.

Graetz Präludium 23F – fr

6th septembre 202430th septembre 2024

From the Second World War until the 1960s, Graetz was considered one of the most prestigious radio manufacturers, although it never achieved high sales performances due to the high cost and economic conditions of Europe at that time.
Graetz devices have always been appreciated both for their elegant and refined finish but above all, for the constant search for innovative acoustic solutions and the related patents.
The Graetz Präludium 23F was the most prestigious stereo receiver produced by Graetz from 1966 to 1968.
It is the last tube receiver produced by Graetz. It therefore benefited from all the know-how on tube amplifiers developed by the Berlin company since 1932.
In that period every important manufacturer, German or Japanese, offered a model of receiver, "Receiver" in German. Telefunken produced the two models Opus 2430 and 2550, Nordmende produced the Steuergerät 3004 Stereo, Grundig the Stereomeister series, 300, 3000, 15.
With this device, Graetz entered the delicate sector of "High Fidelity" devices as conceived in that period.
The tuner section is equipped with a multiplexer so that stations that broadcast in stereo are received in stereo, a real gem for the time.
The FM converter is equipped with AFC (Automatic Frequency Control) so that when you tune in close to an FM station the Praludium automatically centers itself at the point of maximum emission making listening pleasant and free from disturbances, as far as the reception conditions allow.
The low frequency stage is classic but with some interesting details. The Volume potentiometer for example is equipped with three sockets for a more progressive variation of the Loudness correction level, thus avoiding the annoying variation of the response curve as the Volume of the device increases, typical of simpler devices equipped with only one or in the best of cases two sockets on the potentiometer.
The feedback circuit and tone control are much simplified compared to the previous configurations used by Graetz designers. The feedback level remains low, ensuring a natural and stable sound.
The controls are very soft, simple and intuitive to operate.

The acoustic tests and recordings that we normally publish for each device on the Compilation page were not carried out because the result would depend mostly on the speakers chosen and not so much on the device itself.

The Ehrich & Graetz metalworks was a factory established in 1866 in Berlin by Albert Graetz (1831–1901) and the tradesman Emil Ehrich (died 1887) under the name “Lampen-Fabrik Ehrich & Graetz OHG” (E&G).
By 1897 the firm was controlled by Albert’s sons, Max Graetz, and Adolf Graetz. The company grew rapidly, and in 1899 a factory complex were built in Berlin, in the United States, France, the UK, and Bombay.
Around 1910-1916 Max Graetz developed the famous Petromax Lantern. Around 1925 the factory also produced radios, and other electrical appliances under the name Graetzor.

In the Second World War, just as in the First World War, the company was part of the war industry. With the use of forced laborers from France, Russia, and the Netherlands the company made huge gains in production.
At the end of April 1945 the factory was claimed by the Russian army.

In 1949 the firm became part of the “peoples” program, “VEB-VolksEigenerBetrieb” and since 1950 “VEB Fernmeldewerk, Berlin Treptow (RFFT).” VolksEigenerBetrieb, means that the factory was owned by the people for the people (Communism).

In 1948 Erich, and Fritz Graetz founded a new company in Altena, Germany known by the name The Graetz Firm, which was successor to the lost family company in Berlin. The new company produced mainly radios, and televisions.
In 1961 the company was then sold to Standard Elektrik Lorenz (SEL) AG, but since 1987 has been to the present owned by the Finnish company Nokia.

Grundig 3055/56 – fr

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 Grundig 3055/56 was the most powerful radio model with a class A amplifier produced by the German company in 1956.

The FM converter stage is particularly interesting. In fact, it is equipped with double amplifier and oscillator circuits that can be selected via two buttons on the front. Furthermore, in the dialglass there are two identical FM bands, FM1 and FM2. Pressing the UKWI button and rotating the tuning knob will move the UKWI scale indicator, pressing the UKWII button and rotating the tuning knob will move the UKWII scale indicator. In this way it is possible to store an FM station in the UKWI band and another FM station in the UKWII band. The Grundig 3055 and 4055 are the only radios in the entire German production of that period to have two FM bands.

Unlike the previous model, Grundig 3055W/3D, the 3055/56 model is equipped with a rear socket for the remote control. The remote control allows you to turn the device on and off, vary the volume and choose one of the predefined equalizations present on the remote control.

The low frequency stage is an excellent example of a Class A amplifier with the famous EL84 pentode with well-known sonic characteristics.
The preamplifier is made up of the triode section of an EABC80. The circuit is classic and very well tested. The high quality of the sound is given by the excellent quality of the output transformer and its considerable size, which together with the good quality of the air gap laminations and the alternating winding of the copper layers reaches saturation very late.

The feedback, as usual, is moderate, and intervenes on the response curve. The resulting sound is very open, with great presence on the medium and high tones and sufficiently damped bass.

The cabinet is very sturdy and free of vibrations and resonances.

The speakers:
There are five speakers, three on the front and two on the sides.
It is a huge elliptical full-range driver and two electrostatic tweeters. On the sides we find two large elliptical full-range drivers.
The entire frequency range is sent to these full-range drivers with a slight cut in the upper part, in reality the actual cut of the upper part is mechanical.

All this translates into an exciting dynamic, brilliance of sound, lack of oscillations of the canvas in the presence of low frequencies, making listening to this beautiful device very realistic and pleasant.

The first song is by Etta James, it is I'd rather go blind recorded live in Montreaux in 1975. Etta James whose real name is Jamesetta Hawkins is one of the most beautiful and famous voices of blues and rock. Also memorable is her "At last" published in 1960. Etta passed away in 2012 due to diabetes and a serious leukemia after having fought for years with health problems and drug abuse. The song was written together with a singer-songwriter from Detroit, Ellington Jordan (Fugi), while the latter was in prison. In her autobiographical book James wrote that the song was about having been blind in her love life and in her daily habits. The version that is proposed here was recorded live in Switzerland, at the famous Montreux festival in 1975. In this interpretation Etta James, already a mature artist, was able to involve the audience by showing off her powerful voice, singing at times even without a microphone, and also exchanging a few jokes with the audience during the song. A true artist.

The second song performed by Chico Barque is entitled O que serà (a flor da pele). This very famous song is by Milton Nascimento (Milton Silva Campos do Nascimento), a recognized Brazilian composer who has collaborated with artists of the caliber of Wayne Shorter, Pat Metheny, Paul Simon, Cat Stevens, Quincy Jones. O que serà is a sweet song, in the classic Brazilian melodic style that tells of falling in love and its inevitable consequences, "What will it be, What happens inside us and what shouldn’t ... Who have no rest, nor will ever have, Who is not tired, nor will ever be, What has no limit". Francisco Buarque de Hollanda, real name Chico Barque is a Brazilian singer-songwriter, politically engaged against the Gorillas regime, exiled in Italy in 1969, he is also a poet, screenwriter and novelist. He also played with Stefano Bollani.

The third song is performed by Louis Armstrong, and is the famous song What a wonderful world. It is a song written by Bob Thiele and George David Weiss expressly for Armstrong. The two, Thiele and Weiss, were not yet very well known and the collaboration with Armstrong was an incredible opportunity for them. It was such a huge success that it overtook the Beatles from the first place in the English charts. In the USA it did not have the success it deserved because it was hindered by the number one of ABC records, Larry Newton, who wanted a swing song in the wake of "Hello, Dolly!" Armstrong was 62 years old at the time, his lips destroyed by the mouthpieces of the trumpet and his heart suffering, Thiele and Weiss created something that Louis could sing with his heart rather than with his voice. The song celebrates the wonders of the world, the beauty of nature and kind people. The song was included in the soundtrack of "Good Morning, Vietnam" directed by Barry Levinson.

The fourth song performed by Luciano Pavarotti and Barry White is the equally famous You'r the first, the last, my everything. Peter Sterling Radcliffe, a friend of White, wrote it in 1956 in a country style, calling it "You're My First, You're My Last, My In-Between". When White heard it, in 1973, he immediately liked it. While keeping almost all the chords, he changed almost all the lyrics and the melody. White had worked as the manager of the female trio "Love Unlimited" in the 60s and 70s. From 1972 he began recording under his own name. "You'r the first, the last, my everything" was released in 1974, on the album "Can't Get Enough" and was an immediate success. Pavarotti's splendid voice made it even more enjoyable.

MEASURED TECHNICAL FEATURES

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

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.
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.
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.

BANDWIDTH

Normally the measurement of the bandwidth is done on a resistive load. Therefore, the deformation 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.

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.

Grundig 5005W Enhanced- fr

21st février 202421st février 2024
par giovanni

The Grundig 5005W was the progenitor of a new line of Grundig radios model. The 5005W line will be followed, with some modifications, by the 5010, the 4010 and other less and less prestigious series.
From the previous top of the range model, the Spitzen-Super UKW 495W inherits the beautiful full-range speakers, one of which is equipped with a coaxial electrostatic tweeter.
There are also many mechanical elements in common with the 495W, the chassis has a very similar setup as does the high frequency group and the variable capacitor, the keyboard and much more. The tuner section is instead more elaborate, sensitive and selective and the low frequency section has completely changed.

The FM converter stage is interesting. Unlike the usual stages composed of the classic ECC85 double triode (specially designed for this), an ECF12 pentode/triode was used on the 5005W. The pentode section is used as an antenna amplifier and is very quiet for a pentode. The triode acts as an AF oscillator. There is then a further medium frequency amplifier pentode, an EF15, before entering the grid of the ECH11 amplifier/mixer.

The low frequency stage is an excellent example of a Push-Pull amplifier, with two EL41s, the most powerful compact tubes at the time.
The phase inverter stage consists of a double triode Ecc40 in "Anode follower" configuration. Also in this case the characteristics of the tube are important. To have correct driving of the two final EL41s, which work in Push-Pull, one on the positive half-waves and one on the negative half-waves, it is advisable to check the signal present on the two grids of the final pentodes. The configuration of the inverter might make you think that the two triodes of the ECC40 work symmetrically, but this is not the case. The first triode works as a preamplifier while the second has only the purpose of inverting the signal, indeed, it has a slightly negative amplification. The advantages of this type of inverter are the high voltage available at the output to effectively drive the finals and the high rate of internal feedback which guarantees a high linearity of response compared to other types of cheaper inverters.

The counter-reaction is moderate, and affects the response curve. The resulting sound is very open, with great presence in the mid and high tones and sufficiently damped bass.
The cabinet is very robust and free of vibrations and resonances.

The speakers:
There are three speakers, all on the front.
These are two full-range cones of 25 cm each and a coaxial electrostatic tweeter which is inserted when the TA button or the UKW/FST button is pressed.
The advantage of having two separate full-range speakers is that for the same amount of air moved, the cones and the voice coil support are much lighter to move, so each speaker is much faster and more responsive. All this translates into more responsive and muffled bass and without serious resonances.
The die-cast baskets ensure the mechanical rigidity of the speaker itself, therefore again reduction of resonances and greater efficiency of the transducer (no force is dissipated in the vibration of the basket).
The entire frequency range is sent to the full-range speakers and the high part is cut mechanically.

The front canvas covering the speakers is never completely transparent from an acoustic point of view.
For this reason the only way to obtain maximum performance from the appliance is to eliminate it.
We can build a false frame in which the original canvas has been installed. This frame attaches to the speaker panel with magnets.
In this way it is possible to detach it when you want to listen to music with maximum transparency and put it back in its place when the radio is at rest to protect the speakers from dust and to restore the original aesthetic appearance of the device.

All this translates into exciting dynamics, brilliance of sound, lack of canvas oscillations in the presence of low frequencies, making listening to this beautiful device very realistic and pleasant.

The first song is the famous Moanin' written and arranged by Charles Mingus. There are actually two different jazz classics called "Moanin'." Both are blues-based songs with gospel music influences. Both evoke, in different ways, a sense of pain but also a sense of exuberant life.
The song was recorded in 1959, the group members included four sax players, John Handy, Jackie McLean, Booker Ervin and Pepper Adams, two trombones, Jimmy Knepper and Willie Dennis, Horace Parlan on piano, Dannie Richmond on drums and Mingus on bass .
The original lyrics of Moanin', by Jon Hendricks and known on the popular album by Art Blakey and the Jazz Messengers, begin like this:

Every Mornin' finds me moanin'I'm alone and crying the bluesI'm so tired of paying the duesEverybody knows I'm moanin'

Every evening I am moanin''Cause of all I the trouble I seeLife's a loosing gamble to meEverybody knows I moanin'

Lord, I spend many a days and nights alone with my griefAnd I pray, really and truly praySomebody will come and bring me relief

The second song is "Smooth Operator" published by Sade in 1984. It was the song that made Sade famous in the USA. The song appears on her debut album, Diamond Life. "Smooth Operator" is about a charming con man who seduces high society women into getting money from them and breaking their hearts.
Despite the cold-hearted lyrics, this song is also often used in cinema in scenes of a romantic encounter.
An interesting curiosity: the music producer Robert Millar recorded the song for a demo to present to the record company to obtain a contract. Epic Records liked it so much that he released it exactly like that, without having it recorded again in the studio.

The third song is Walk On The Wild Side by Lou Reed. The song is very well known. From a musical point of view it is rather simple, supported by a bass line with repetitive "Du du du" choruses and an interesting baritone saxophone solo. The text, however, is the most provocative one could have imagined at the time. It talks about the gender world and male prostitution. Each verse introduces a new character, Holly (Holly Woodlawn), Candy (Candy Darling), Little Joe (Joe Dallesandero), Sugar Plum Fairy (Joe Campbell), and Jackie (Jackie Curtis). All cronies of the Andy Warhol Factory, as well as Lou. A cross-section of the Big Apple's underground.

The fourth song is Yakety Sax written by saxophonist Boots Randolph and guitarist James Q. "Spider" Rich. The song became famous as the closing song on The Benny Hill Show. It is a piece of "instrumental novelty song", a light piece of music which is usually, but not in this case (instrumental), accompanied by a fun and topical text. The song is inspired by Yakety Yak recorded in 1958 by the Coasters from which it took its title. Yakety Yak is a slang expression that means to talk for a long time for nothing, to chat in vain.

And finally, to really put the device to the test, the final part of the drum solo from Led Zeppelin's Moby Dick. In this piece the skill of John Henry "Bonzo" Bonham is expressed at the highest levels. Artistic heir to Ginger Baker, Bonham had developed spectacular right hand/left hand/foot sequences, which were particularly exciting for him in live concerts. The piece is really difficult and requires great strength, and probably also great anger. Bonham's life was filled with fights, trashed hotel rooms, drinking, orgies, except when he was at home in his cottage in Worcestershire. Bonham died at the age of 32 after choking on his own vomit one drunken evening.

MEASURED TECHNICAL FEATURES

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

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.
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.
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.

Grundig 4055/56 Enhanced – fr

The Grundig 4055/56 was the most prestigious model produced by the German company in 1956.

Unlike the previous model, Grundig 4055W/3D, the 4055/56 model is equipped with a rear socket for the remote control. The remote control allows you to turn the device on and off, change the volume and choose one of the predefined equalizations on the remote control.

The low frequency stage is an excellent example of a Push-Pull amplifier, with two EL84s with well-known sonic characteristics.
The phase inverter stage is made up of an Ebc41 triode, the preamplifier is made up of the triode section of an EABC80. The circuit is classic and very proven. The high sound quality is given by the excellent quality of the output transformer and its considerable size, which together with the good quality of the air gap laminations and the alternate winding of the copper layers reaches saturation very late.

The feedback circuit as usual, is moderate, and affects the response curve. The resulting sound is very open, with great presence in the mid and high tones and sufficiently damped bass.
The cabinet is very robust and free of vibrations and resonances.

The speakers:
There are five speakers, three on the front and two on the sides.
These is a very bug full-range speakers and two electrostatic tweeters on front. On the sides we find two elliptical widebands.
The entire frequency range is sent to these full-range speakers with a slight cut in the upper part, in reality the actual cut in the high part occurs mechanically.

The front canvas covering the speakers is never completely transparent from an acoustic point of view.
For this reason the only way to obtain maximum performance from the appliance is to eliminate it.
We can build a false frame in which the original canvas is installed. This frame attaches to the speaker panel with magnets.
In this way it is possible to detach it when you want to listen to music with maximum transparency and put it back in its place when the radio is at rest to protect the speakers from dust and to restore the original aesthetic appearance of the device.

All this translates into exciting dynamics, brilliance of sound, lack of canvas oscillations in the presence of low frequencies, making listening to this beautiful device very realistic and pleasant.

The first song is by Pink Anderson, it is Baby Please Don't Go. Pinkney Anderson was born in Laurens, South Carolina on February 12, 1900. At 14 he joined Dr. Kerr of the Indian Remedy Company to sing and dance to the public in the streets while Kerr sold his elixirs which he said had medicinal properties. In 1928 she recorded for the Columbia label. In the 50s and 60s she recorded other albums and performed live. She died in 1974 of a heart attack. The song "Baby Please Don't Go" tell about the anxiety of a recluse over the departure of his lover who is about to leave him to return home to New Orleans.

The second song is by Floyd Council, it is called Looking For My Baby. Council was born in Chapel Hill, North Carolina, on September 2, 1911. At 15 he performed on the streets of Chapel Hill with two brothers, Leo and Thomas Strowd. In the late 1920s and early 1930s he and Blind Boy Fuller busked in the Chapel Hill area. In the 1930s he recorded some songs for ARC but very few Council recordings remain. In a 1969 interview, Council stated that he had recorded 27 songs over the course of his career, seven of them as backing tracks to Blind Boy Fuller. In the late 1960s he suffered a stroke that partially paralyzed his throat muscles and slowed his motor skills. Peter B. Lowry attempted to record it in 1970 but Council was unable to sing or play. Council died in 1976 of a heart attack.

The third song is naturally by Pink Floyd and it is a rare live recording, Live at the Rainbow Theatre from 1972 . Syd Barrett created the band's name by juxtaposing the first names of the two bluesmen Pink Anderson and Floyd Council. Pink Floyd's most famous LP, "The dark side of the moon" was the product of an intense year of laboratory work, tested and perfected thanks to over a dozen live bootlegs such as this recording at the Rainbow Theatre. The arrangements of these recordings often vary greatly from the final LP. Unfortunately the recording is of very poor quality, but for enthusiasts this is certainly not a problem.

The fourth song is O Tempo E O Lugar by Ana Caram. The song is by Sueli Correa Costa, the talented Brazilian singer-songwriter who died last year. She recorded for EMI with important partners such as Cacaso and Tite de Lamos. She sang about love like few others and left a definitive mark on our music, with songs that had the rare combination of sophistication, elaboration and beauty, fluidity and the ability to reach a wide audience. Her compositions, however, have been interpreted by artists such as Simone, Elis Regina, Fagner, Maria Bethânia, Gal Costa, Beth Carvalho among many others.

The fifth song is Litany by Arvo part. A characteristic of his style is that his songs arise from silence, grow, loading themselves with effect and then descend back towards silence. This technique originates from Part's initial twelve-tone influences, especially from Webern, although Part ideologically abandoned this current, realizing that it carried within itself the seeds of a conflict, in particular against capitalism. Coming to the firm belief that every conflict originates within oneself.
Having been commissioned by the Oregon Bach Festival, Litany Part uses the English language for the first time. The text is by Giovanni Grisostomo, a great theologian born in Antioch in Syria (currently in Turkey). The English terms being short do not allow for a structured musical elaboration, however the initial dialogue between the prayer and the immediate, or rather anticipated, response of the violin indicate the response from heaven. Before man can ask God for help, God is already close to him.

The sixth song is Il Cielo In Una Stanza performed by Mina. Gino Paoli's most famous song had a very troubled origin. He was judged by Giulio Rapetti (aka Mogol) with phrases like "this is not a song", "it's better for you to change jobs", "it absolutely can't go" and even worse by Miranda Martino who refused to interpret it. Then Mina arrived and wanted her to sing it instead. Arranged by Tony de Vita, Mina, as soon as she finished singing it, started crying and all the musicians stood up moved.
The song talks about orgasm and is dedicated to a prostitute with whom Paoli had fallen in love. In the song the unsaid suggests sensuality with the description of the environment.
