Description:

The Philips 12RB770 is one of the latest tube radios. It belongs to the German named Capella series and usually these are the most luxurious series of the tube radio sets.

Repairs:

No repairs are done, except the reverb unit is placed back into place.
For an unknown reason, the AM reception is dead and so far no actions are taken. This need still to be done in the future.
The FM stereo lamp doesn't also light up, but there is FM stereo sound.

Performance:

Performance is good. Audio quality is good en the FM Stereo reception is also good.
