You can't just assume it's bad unless you've run through the horizontal setup in the manual, could be as simple as an efficiency coil adjustment or some damper/output tube rolling. HV rectifier could be gassy, or there may be leakage in old HV wiring or conductive dust in the cage. I have a Packard bell chassis right now that overheated the fly first time I ran it and cathode current was only 190, let it cool overnight and when I powered it up the next day it was fine. Moisture in the transformer also causes issues sometimes.
