OK, there is a nasty 60 Hz saw-tooth waveform at cap #67 going in to the audio amplifier and it's getting amplified nicely by the push-pull 41s.

Link to schematic in case you're interested:

EDIT: After much poking and prodding, I still have no idea what has gone wrong. I am still very unfamiliar with vacuum tube electronics. Any help would be very appreciated.
