I recently obtained a 38-690. Something must have happened during shipment (it was well packed) because the set is now "non playing" with only a low hum coming from the main speaker. Set was playing before it was shipped I was told.

I'm starting with the power supply and will rebuild that and check it with audio input.

A number of electrolytic caps have been replaced at some point with large 600V units (not checked yet). I have the original Philco parts numbers for the caps that should be there but I can't find a cross reference to the working voltage of the original caps. Would they have been higher than 450V?? Parts numbers are as follows:
30-2200 (18uF)
30-2025 (three of these 8uF)
30-2249 (multi section)
30-2201 (8uF, 10 uF)

The Philco parts list and schematic shows the capacitance values but no voltage values.
This is going to be a long slog. The power supply doesn't look too bad but that chassis is really intimidating..

Thanks, Mark
