Re: Reviving Radio in old German Radiogram
This suggests the amplifier section is faulty and is likely to mean you will get no sounds from the Tuner section either. Try a contact cleaner on the piano keys and actuate them.
If no joy, you will need to signal trace the circuit. Best starting with the amplifier section first. But before you do this, we need to know what confidence/experience you have to work on the circuitry within the chassis of this, especially when it's powered up?
