Take the tone cont. out of the circuit and test again. The plate of the 42 should be around 240 volts. If that voltage is being taken to ground it could be very bad for the OP transformer and/or the power supply. So test right after warm-up and carefully.

What are you using to measure voltage? Can you measure all of the pins on the 42 for DC volts except the filament(s) contacts?
