The Thomas organ paragraph about TO3's (Output Transistors/paragraph 5) was the problem. The old TO3's grease dried out, two overheated and shorted. I need new mica washers and dielectric grease and maybe new sockets?
The premise of the article (Output Transistors/paragraph 1) is the old Germaniums are $20 each and matched pairs are hard to find. I can get them from "guitarampsky" for $50 with shipping (eight with a foot of fusewire.
I will still need a new driver transformer ($35 with shipping), even for the silicone replacement fix.
