OK, now that I've gone through it I've found 4 transformers out on this guy. I've located a used model 65 power supply, but still need to track down the rest (including whatever's blown on the speaker.)
Couple of question on this:
- The second filter choke is open. Specs are 150H, 10ma, 4000 ohms winding. Hammond makes a 150H, 8ma, 3700 ohm model. Is this close enough?
- Can't find any info on the push-pull transformer to the two 45 tubes. I believe this is called the "audio interstage" transformer; it sits between the 27 tube and the 2 - 45's. #17 on the schematic. What can I use on these? Looks like Hammond has a handful of "generic" varieties.
