SCHAUB LORENZ GOLDSUPER 58

Schaub-Lorenz radios are recognizable at first glance.
In the 1950s-60s the concepts of industrial standardization, of cost optimization and of inter-enterprise economies of scale did not exist.
Industrial products – not only radios, but also cars, motorbikes and domestic appliances – were characterized by great differences, at least aesthetically, from on brand to another.
It was not necessary to read the brand on the trunk in order to distinguish an Alfa Romeo from a Citroen or a NSU.
Radios were also easily distinguishable. Some maintained an austere look, some wanted to give a strong appearance of solidity, some others had eccentric and catchy shapes.

At Schaub-Lorenz, designers and developers' efforts aim for the elegance of their prestigious devices.
Schaub Lorenz Goldsuper 58, in fact, has a very elegant line. Every detail is tastefully designed with great sense of balance.
The front and the sides are designed to give great lightness to the device. There are no parallel elements or surfaces on the cabinet of this device.
Flat surfaces are minimised and the residual uniformity is completely shattered by the nuance effects that make the device look like it is moving.
The shape of this device seems to transform according to the lights and shadows around it.
Apart from my expressive skills, a simple photo array with devices of other renowned brands will clear all doubt.

GoldKlang 58 is the company's top model of the same year and GoldSuper 58 only differs from the first for the final stage.
Instead of two ECL82 in counter-phase with an output power of 5,8 w, it has an EL84 with an output power of 4,4 w.
But in the GoldSuper, the final stage works in A class, which avoids the problem of Crossover Distortion.
As usual, the sound is smooth and bright, with warm and pleasant low tones.
The loudspeakers are oversized, in fact on the Goldklang the same transducers are installed.

The tuning knob is very pleasant to use because of the peculiar pulley movement transmission system.
The keys are soft and safely activated and jam-free.

The restoration was particularly challenging because of the difficult reconstruction of the shades of the cabinet. It was laborious to recreate the precise balance between the background colour and that of the shade, as well as to respect the nuance gradient.
But the result definitely pays off.

HISTORY

In 1870, Carl Lorenz (1844-1889) opens a lightning hardware shop in Berlin.
After his death, the company is acquired by textile entrepreneur Robert Held (1862-1924).
Carl's brother, Alfred Lorenz, is appointed as technical director. Under Held, the company became an important supplier of telegraphy equipment.
The company expands in the telephone industry buying Lewart and it becomes the telephone provider for postal service.
In 1906, the company is registered for public commerce as C. Lorenz AG.
At the beginning of World War I, Lorenz had reached the number of 3.000 employees and was an important provider of telephone and telegraphy equipment for the German army.
At the end of the First War, the size of the company decreases considerably and activities are oriented to the production of household radios and aeronautical communications devices.
In the 1920's, the company is the main competitor of Telefunken.
In 1930, it is under the control of Standard Elektrizitätsgesellschaft, a branch of American society ITT.
Lorenz patented the ferrite aerial in 1935, which has been used since then in most domestic receivers.
While Germany was preparing for another War, Lorenz went back to the production of material for the army.
In 1940, he aquires G. Schaub Apparatebau-Gesellschaft; its many factories were mainly used for low-cost production.
Lorenz's military products during World War II included land and air radars, radios, recorders, radio tubes and the safest communication device in Germany, Lorenz's machine and code.
Lorenz owned the 25% of Focke-Wulf, the German aeronautical company that built some of the most successful Luftwaffe fighter jets.
In the midst of the War, Lorenz had about 24.000 workers in 12 operating structures.
In 1948, Lorenz has to start over.
Some factories had been shut down and those in the eastern part had been transferred or transferred to the Soviet Union.
During the 1950's, Lorenz recovers very quickly. In 1954, the name of the broadcasting devices brand is changed to Schaub-Lorenz.
In 1958, C. Lorenz AG ceased to exist as an independent company. ITT reorganizes its activities in Germany by merging Lorenz, Standard Elektrizitätsgesellschaft and many more into a new society, named Standard Elektrik Lorenz (or SEL).
In 1961, the company also becomes the main shareholder of Graetz.
In 1987, it is incorporated by the French company Alcatel.
In 2016, Alcatel is bought by Nokia.

NORDMENDE TANNHAUSER 58

NORDMENDE TANNHÄUSER 58

Nordmende Tannhäuser 58

Tannhäuser, born into a family of knights in Salzburg, took part maybe in the sixth Crusade of 1228 and led a wandering life as a poet and a bard. He attended the court of Duke Frederick II in Vienna.
According to legend, during his life Tannhäuser found the Venusburg (mount of Venus), the subterranean reign of Venus, and lived with her for one year. He then left the goddess, full of remorse, and undertook a journey to Rome, in order to ask Pope Urban IV for forgiveness. The Pope reminded him that such sins lead to eternal damnation and promised to forgive him only in the event of a miracle: the appearance of flowers on his cane. Three days later Tannhäuser returned to Vienna and the cane bloomed.

The legend was put into music by Richard Wagner in his Tannhäuser.

Nordmende, in its heyday of technological growth, decided to name “Tannhäuser” its best device ever produced.
A device designed to represent the crest of the technical perfection of its time and extreme attention to detail.
The output stage is composed of a pair of  EL84 in Push-Pull. The phase inversion is carried out with a section of the double triode  ECC82 in Cathodyne configuration. This kind of inverter has an advantage, the possibility to be connected directly to its previous stage. Such stage consists of the remaining section of the double triode ECC82, which provides for the amplification of the signal after the attenuation deriving from the tone control circuit.
The triode contained in the multifunction valve EABC80 constitutes the input preamplifier and receives a signal from a logarithmic potentiometer with 3 intermediate sockets for a complex and very accurate physiological volume control circuit.

The radio section is of the same high quality. An additional medium frequency stage is present, in order to increase the selectivity.
This allows the receipt of transmissions, especially in FM, particularly stable and free from disturbance.

The complex of loudspeakers, moreover, is really impressive. All the loudspeakers are made by Isophon.
The reproduction of low and medium frequencies is ensured by a big elliptic woofer  P 2031/19/105 which measures 31 cm in length and 20 in height.
To trebles, instead, are dedicated 4 loudspeakers built with 3 different technologies.
Frontally, we can find the famous cone tweeter HM 10/12/70 for a soft reproduction, perfectly integrated with that of the woofer. The trumpet exit of a DKS 6/13/100 and an electrostatic tweeter ST HB7 were put  on each side.

As Baudelaire wrote, the Tannhäuser represents the struggle between the two principles which choose the human heart as their battlefield, that is the flesh against the spirit.
Nordmende honoured this great piece of work with the realisation of its best product.

HISTORY

In 1923 Otto Hermann Mende founded Radio H. Mende &amp; Co. in Dresden. After the bombing of the factory in 1945, Martin Mende (son of the founder) created a new company in Bremen, the "North German Mende Broadcast GmbH" whose name was later changed into NORDMENDE.

In the 50s and 60s it became one of the most prestigious German TV and radios manufacturer.

In the 70s the televisions by NORDMENDE became famous for their frames, cards and for the rigorous testing and quality controls carried out on their finished products. Unfortunately, the high cost involved in such detailed quality determined a competitive disadvantage when the price of color television began to fall.

In 1977 the majority of the shares was sold to the French Thomson. The following year, the family sold the remaining shares. In 1980, the factories of Bremen was closed, NORDMENDE becoming purely a trademark of Thomson.

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 see the rotation mechanism and the position indicator of the aerial.

The reception sensitivity with internal aerials is very good. This unit was in fact produced in a period when there were not many radio stations and those available fairly apart from each others.
Using an external aerial sensitivity is further increased.

SEPARATE CONTROL TUNING BETWEEN AM AND FM

The tuning system is another gem.
The unit is equipped with mechanisms for keeping separate the AM and FM bands.
The tuning knob is single but a selector switch commutes into cable systems (all in steel) and pulleys separated depending on the band.

The movement is transferred to both mechanisms with a system of pulleys and separated gears.

In order to obtain a 3D effect, we find on the sides a huge trumpet tweeter with two outputs and two electrostatic SuperTweeters.

 The acoustic performance is really generous.

 None of the radios I know has the same dotation of loudspeakers.

CONTROL PANEL

Nordmende Tannhauser 58

Above the dial, in the loudspeakers panel we find the series of buttons of the Bandbreite Schltbar, previously described.
Moving downwards on the tuning-dial, we first find the magical eye, which indicates the perfect tuning of each station. Below, we find the volume control (with integrated loudness).
By pulling the volume knob, the circuit which powers selectivity in the AM bands is inserted.
From the top down are then indicated the AM dial for Long, Medium and Short bands and below we find the FM dial.
Moving further right, we find the indicator of the position of the ferrite aerial.
Finally, there is the tuning knob, which movement is very pleasant as it is supported by a big flywheel.
Coaxial to the harmony knob is the knob which rotates the ferrite aerial.
Below on the left we find the treble control knob set in a nice bakelite casing with ivory effect.

In the following order, then, we find the buttons:

AUS - Off
TA - Turntable
TONBAND - Tape recorder
L - Long Wave
Peil-Ant - Ferrite antenna for  LW and MW
M - Medium Wave
K - Short Wave
UKW - FM

On the right, the bass control is visible.
Above the tone controls, the respective emphasis indicators of the controls.
