Philco 77 hacked?
#15

Power transformer has a bad secondary (lines 9-12) everything that supplies the 80. I was using the needle probes when I looked at that. It's sad. I got excited getting good ohmage on the windings at lugs 1-8. That is why that repair person in the 40s or 50s added the second transformer. I can't imagine how much power the set used with two power transformers. The 32-7180N was only connected to the rectifier and to the mains and the pilot light (wrong in the first place). All the other windings test good, though. I put the set back in the chassis yesterday, but I will take it back out and start over this evening. The soldering that guy did is a mess as well. Big, gloppy misshapen masses with untinned leads everywhere he worked. The good news is that he only worked at the power supply end. No changes past the capacitor block at all, but time has not been kind to the wiring above the chassis, so I will need to do some careful tracing around the pilot light/tuning cap/volume pot areas.
I'm going to give re-coning the H a stab. I emailed John's Vintage and he wants $100 to do the job and the guy in Ohio will do it for $50. Worst case, I can buy a replacement for less and still have some backup parts around. Has anyone ever dealt with these guys before? https://taweber.powweb.com/parts.htm
