should be about 3-4 ohms on the plug. with the power switch on.
if that checks then check resistance at B+ (right after the choke), should be around 10k AFTER the filter caps charge up from the voltage of the VOM, do this with the set unpluged of course. If the B+ resistance is a lot lower then you have a short somewhere or a filter cap installed backwards. If it uses a doubler cap in the power supply make sure you have it wired up with the correct polarity, check it to the schematic, doublers can be tricky.
