I am still trying to figure this out. I took both cans off the IFs and did not see a broken wire so I attemping to use an ohm meter to make sure the coils are ok. The first IF coil, according to the schematic shows one side of the coil going to pin 3 of the plate of the 6a8 tube socket and the other end going to the shadow meter. (But there are 2 shadow meter wires I do not know which one to properly check)
The other coil in the first IF goes from the grid of the 6k7 tube, but there are 3 grids I do not know which one(pin) to test and then connects to ground.
I hope someone can help. I am still to new at this to figure this out. Once I get this one, I can verify the 2nd IF. Thanks, John
By the way, I have finally got a schematic file that did not fail so it is attached. I had to rescan a new version and it worked. (FYI) the IF transformers in the schematic are parts# 33 and 34.
