If the tubes are lit up and appear normal, it could be a preamp failure (like an op-amp), low-voltage power supply failure (this feeds ONLY the preamp) or your 12AX7 phase splitter tube opened internally.
It could also be the failure of a series interstage coupling capacitor or a failure of the standby switch or the output transformer itself (least likely).
Does cranking ANY of the pots full up make any difference at all to the output? Make sure that the tremelo AND the reverb are turned ON with the footswitch. Does this make any difference?
