[devoid]

A Telefunken Govotte 5353. Or something similar. After it's on for 15 minutes or so the soung drops way down. Seems to be in the audio amp section as when I turn up the volume it crackles loudly. Tried circuit chiller on many suspect parts with no success. Also if you turn the radio off for 5 seconds and then back on it play normally for a few minutes before going down again.
