Hi. I'm new to this forum, and new to radio repair.
I have what I believe is a Philco 38-40. I rescued it from a dumpster several years ago.
Aside from a few scratches, the case is in pretty good shape, and there is no apparent butchery inside.
When I first found it, I plugged it in, and nothing happened.
So, I've now read about what to do before you plug an old one in.
In spite of my (very) limited electronics experience, I intend to get this old girl running again. I think I have a grasp of what to do first, but I hope someone will correct me if I am wrong.
I intend to replace all of the capacitors (condensers, etc...) except for the mica condensers. Then, test the diode values. Then, power up with a dim bulb, or a variac (if I've found one cheap).
I'm sure that once I've gotten this far, I'll have a lot more questions.
I'm not the best at reading schematics, so does anyone have a cheat-sheet that tells me which caps I need to buy to get started?
