I need help. I read up on restoring old radios and it looks like I need to replace the capacitors in the power supply. So I pull out the schematic for the power supply and it looks easy enough. Only my power supply is not the factory one. It looks like a homebuilt job and I have no schematic for it. It seems way more complicated than it needs to be. Anyone in the So ME/ NH or Northern MA that can take a look at it?

Pictures would help.
If the capacitors aren't too old they may be OK after a gentle bring-up (re-forming the dielectric). If you have a Variac you slowly increase the input voltage from zero to 120VAC over several hours or days. If you apply the full 120VAC right away something will probably go KB.

I know a guy who is crazy good with them. PM with details if you would like to send it to be repaired
