Was the transformer wired before you took it out?
If yes, have you made a diagram of how it was wired ?
To check it you do not need to take it out, most leads will go to no-load circuitry with the tubes out.
I usually check it by inserting V-meter in the rectifier tube's panel between the two plates and supplying it from a Variac into the AC in wires.
Start low, see the voltage going up; if it does, simply move it to 110VAC on the Variac and see if it reaches 500-600VAC between the plates.
After that do the same with the V-meter in the filament's pins in the panel. Should go to the rectifier tube filament voltage (say 5V for 80 tube),
Then leave it on a bit, see if it warms up significantly which it shouldn't.
