Hello, I've recently aquired a model 77 Lowboy radio. It does seem complete, however it has issues. (At 78 yrs old it's not surprising!). First, the veneer on the top and one side needs replacing. Does anyone know what type of wood was used?
As far as the innards go, the set will play (make noise) when it warms up, then the sound fades away after about 30 seconds. I noticed the voltage on the load side of the resistor @ point "G" on the schematic, drops consistantly with the fade. The resistor checks ok. I don't want to disturb too much in there, does anyone have any ideas? What is the normal voltage supposed to be at this point? Voltages are not listed on the schematic. Any help would be greatly appreciated. Thanks, Dan
