TELEFUNKEN Orchestra 53
AEG 2083

Telefunken Orchestra 53 and AEG 2083 are exactly the same device under a different name.
It is important to underline that Telefunken is a joint venture between AEG and Siemens. It was created in order to produce professional and consumer radio devices.

In 1953 it was Telefunken's top quality model. The brand was one of the most prestigious german companies.
This device is characterized by a great number of remarkable features.

An example is the FM oscillator stage for which an expensive ECC81 tube with high gain was employed.
An extra medium frequency stage was added in all bands in order to obtain a better sensitivity and selectivity than other excellent german devices.
An aerial amplifier stage for AM bands was added in order to further improve the sensitivity in these bands that were extensively employed at that time.

Equally refined solutions were used on the Output stage

Pure A class with a powerful EL12 tube was used on the output stage.
Usually the outupt transformer distorts the sound. The bigger the output
transformer the less the sound is distorted. This device has a very big transformer.
Moreover, to balance the frequency response a feedback system was used.

Professional louspeakers were used, the same that were employed in some theater loudspeakers. Clearly a greater number of the latter was used in theaters.
Due to its high quality the woofer is usually traded on ebay for USD 180.

With this business card to introduce it, this device cannot but save some great surprises for us.
With its stable tuning and relaxing sound the Orchestra 53 can be easily played in spacious rooms.

For those who want to start a collection with a great piece.

Here are some pictures of the AEG 2083. As you can see, but for its front logo, there is no difference compared to the Orchestra 53.

Back to my Telefunken Concertino TS’s review where I argued that the peculiar tuning lever and its fly-wheel reminded me of Fellini.
With this device I would update my argument saying that it reminds me of “The Great Beauty” where Fellini is undoubtedly still a strong presence.

Rotating OM aerial

AERIALS

Inside the cabinet there is a dipole for FM reception and a ferrite rotating aerial for AM reception.

The reception sensitivity with internal aerials is very good.
Using an external aerial sensitivity is further increased.

This unit was in fact produced in a period when there were not many radio stations and those available fairly apart from each others.

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.

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.

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

The tuning indicator is new

CONTROL PANEL

In the high left side corner we find the magic eye that indicates the perfect tuning station.
To the left is the volume control (with loudness built-in). Coaxially there is the ferrite aerial control.
On the left side of the glass we can see the aerial position indicator.
Continuing we find the FM and AM main display for Long Wave Medium and Court bands.
Under the dialglass we find the bass control equipped with indicator on the main dialglass.
To the right in the order there are the OFF, Turntable, LW, MW, SW, FM, Ferrite aerial and External aerial keys.
Further we find the treble control equipped with indicator on the main dialglass.

Finally, there is the tuning knob.

LOUDSPEAKERS

There are three loudspeakers, which I have already described in the initial comment.

The woofer is really big and efficient.

The radio is equipped with a 18 cm ( 7 inches) Midrange and a conical electrostatic tweeter.

REAR SIDE


Output for external speakers.

Socket for recorder (tonbandgerat).

Turntable input (Tonabnehmer)

AM and FM aerial inputs and ground socket.

RESTAURO

I accidentally deleted the pictures taken while I was restoring and calibrating the radio.
I only still have the two that are posted down below.
