I'm floating around in radio ecstasy. Let me describe what I started with: A Philco 77 from CL for $25. The speaker was badly smashed-in, but for fun I repaired the cone with low expectations. It had no 45s and the ones I'm using test poor. The filter can had been removed and a 20/20 uF with mid-air solder joints was for, I guess, the 2.0 uFs, although there are three! The 2 bakelite blocks are gone and in their place was the worst unsupported mid-air soldering job that I've ever seen. The input xformer is replaced. After a lot of scrutinizing of the schematic, I made nice terminal strips for the bakelite blocks and made a new filter cap board. My hopes are really low at this point because the drawing that I made of the old wiring job, did not appear to match the new work that I completed. So with nothing to lose, I variac-ed it up and at 70 volts, I couldn't believe my ears, it works.
