So I picked up a Mesa Nomad for free, no output, and no glow from the power tubes. Upon closer inspection, no glow from the preamp tubes (They were behind the shields) and only V1 is glowing! I believe V1 is on a separate circuit, and not wired in parallel with the other preamp valves.
Also, the molex connecter from the power transformer was pretty burnt up on the two heater wires. I took out the two heater leads from the molex connector, and soldered them to the pcb. The main pcb has a pair of pads that go to the EL84 board for the heaters, so I soldered the heater leads there. V1 still has heater glow.
I checked the heater pins of the other preamp and power tubes:
I have the correct voltage to ground (3.1VAC) from EL84 pins 4/5 and from 4/5/9 to ground on the 12AX7's, but no voltage between the heater pins themselves, unlike V1 which has voltage between the heater pins.
