Okay.. I have decided the filament transformer in the GE may still be
okay. I've had it connected through a Variac at 100 volts (the stated
primary voltage of the transformer) for about 2 hours and it is barely
warm. I also have a 5R4 filament connected to it as it would be in the
circuit. In addition to that I have about 10 ohms of resistance on the
output causing a current draw of about 450 ma. With all of this it
still seems to be fine and is not heating up at all. However, I need a
way to test the high voltage insulating properties of the secondary
since this is used in a full wave rectifier circuit of about 800 volts.
I do not have a megger or similar device, so is there any quick and easy
test I can perform short of putting it back into the actual circuit to
see if it breaks down under full load conditions?
