Hi and welcome to the Phorum. Nothing like putting life back into an old friend. One of the first things you'll want to do is measure all the coils and transformer windings for continuity, including the speaker. They are probably the hardest things to source if there is an issue. Universal audio output transformers are easily available but the rest are tricky. So you'll want to know right away what you're up against. Above all, go slow, take pictures (both for yourself and us) and have fun.
