This awesome radio is a rare German tube radio manufactured by Telefunken Germany (TFK) in 1957. It contains 7 tubes with 8 AM and 12 FM circuits. It will play almost anywhere in the world with an adjustable power supply providing 110, 127, 155, 220, 240 Volts AC at 55/60 Hz. This Concertino has 4 speakers and a built in AM ferrite antenna as well as a built in FM loop antenna. It has bass and treble tone adjustments, normal and HI FI settings, an external speaker connection, and a record player input which accepts any audio input such as Bluetooth, IPAD etc. with the use of a proper cable.
The radio measures 25x10x15 in.
This cabinet is in ORIGINAL condition...NOT restored, NOT artistically altered - just the way it was back in 1958. There are some imperfections in the finish but not bad for 60 plus years!!
I removed the chassis from the cabinet and cleaned and dusted everything, I tested the tubes, capacitors and resistors and anything that was not in acceptable ranges were replaced. The pushbutton assembly was cleaned with DeoxIT D5 and works nicely. The original finish and metal trim were hand polished and the original speaker grill cloth cleaned. There is a worn spot in the speaker cloth as shown in the picture but in my opinion it did not warrant replacing. I try to maintain as much of the original radio as possible. I did change the magic eye tuning tube with a fresh NOS equivalent so it shines bright and responds well to station changes.
I pick up many FM stations even known weak stations play well. I receive some AM and SW stations but not many. I believe it's the area that I live in. I have many tube radios and have difficulty tuning in stations with all of them on these bands.

Nothing has been done to this radio that is not described here. THIS IS NOT A FULLY RESTORED RADIO but rather an original vintage item that has been inspected and repaired as necessary to make it functional. As with all of my radios, I have played this radio for hours several days a week before I put it up for sale. I do my best to describe every item in detail. Please look over the photos and contact me with any questions.
Vintage radios were manufactured decades ago in a time of relaxed electrical safety. Many early radios were made with the metal chassis electrically connected to one side of the power cord. This can give you a strong shock if you happen to touch the radio and anything else that is at grounded at the same time. In addition, tubes can get very hot and cause serious burns if touched accidently after the radio has been running for a while. The danger is minimal if the complete cabinet, back, and knobs are in place and no metal parts are exposed. Vintage Radio Electronics, whether restored or un-restored, are by nature hazardous due to their voltage, design, heat output and age. They should not be operated unattended or for great lengths at a time. Any operation, repairs or other adjustments are done at your own risk. None of the radios sold at this shop have been modified to modern standards.
The late 1950s, 1960s and 1970s marked the golden era of Telefunken stereo radios, which were known for quality and innovative features. Some of the popular models during this time included the “Concerto” and “Allegro” series. Telefunken products were not only popular in Germany but were also exported extensively, particularly to the United States. Known for their superior sound quality, precision engineering, and stylish designs, Telefunken’s radios quickly gained popularity.
