  • Export model Telefunken Opus 7 is shown in the Photofact Index as being the same as export model Telefunken Opus 6 which is documented clarly in that said set 341 folder 16 from 12-56 Folder. But Opus 7 has at least the 5 additional push buttons for "Solo, Jazz, Orchester, Bass and Intim" in front of the normal 8 push buttons (both models show). There are at least Version A and B or Chassis. The Opus 7 has been made in two quite different cabinets. One has the usual textile speaker grille in front, the other has vertical wooden bars in front and ony cut outs at the sides in the woods for the other speakers. You find two different pages for them - but not different wones for the color variants which show also different glass scales and knobs.

    Until we can deliver schematics for the Opus 7 USA we leave the Opus 6 USA schematics according with SAMS also on model Opus 7 USA. Power Supply 60 Cycles. Supplier was American Elite, Inc., 7 Park Ave., New York.

Dear Members,

I have been working on the restoration of a Telefunken Opus 7.

Per schematics, screen voltage of EF89 in the last IF stage (tube4) should be 25V but I read 40V. All the components around EF89 are OK (C48,C47,W20,W21,C38 and grid resistor).

Anode voltage is around 220V which should be OK as well.

I swapped the EF89 with the one in previous IF stage (which shows the correct voltage values so I assume it is a good tube), still I read 40V. I have tried 3 different EF89s from other radios I have, the result is same.

Any thoughts about this issue?

Thanks in advance,

Cuneyt
