More problems with the audio amp: I found a wiring mistake that messed up the cathode bias on the output tube, causing the amp to remain silent.
After that was cleared up, I finally had a roughly recapped chassis:
But more audio issues were evident: I wasn't getting any audio still, although the amp was sound. I found an IF tube was dead (open filament) but still nothing. Something wasn't quite right with my measurements on the oscillator, and when I pulled the tube, the plate pin remained in the socket. Luckily, I have another 6C4, and when I dropped that in, I finally was rewarded with the sweet sounds of static.
The fly is also good! After capping, HV came up right away! Now, to hook up the crt (really wish I had a mini test crt right now) and see if I am getting a picture!
