I decided to check my voltage readings to see if anything was unusual. The rectifier pin 2 and 8 readings to ground are about 325 V which I understand to be ~ 100 V too low. The voltage readings on pins 4 and 6 to ground are 0.1 mV which I'm assuming this is how my meter reads 0 V.
The voltages on the quad cap and EL 34s are correspondingly low. For the EL 34s, the readings across pins 2 and 7 is 0.2 mV and pin 3 to ground is 0 V.
The quad cap readings range from 276 V to 325 V.
I'm assuming that my power tranformer is toast?? Should I be checking anything else?
