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.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
