Well, I've rounded up the bits for the chassis and am trying to sort it out. The #3 center tap to the 80 tube was gone on the main power transformer; I located a used replacement which is now in place.
There's some funky wiring running to the 80 tube that doesn't match the schematic. The #1 and #2 from the xfrmer are supposed to go to the heater for the 80, with #1 from xfrmer running over to the condenser block. #4 and 5 on the xfrmer go to the other side of the tube, with #3 (the center tap) going to ground.
On this radio, #1 and #2 are wired to the 80, but that's it. The #4 and #5 are wired to the 80, but the #5 goes to the condenser block, rather than the #1.
Follow all that? Maybe a way to keep it working with an open #3 center tap?
Question is, should I rewire it back to original, or leave it alone?
