Remove the tubes and look to see if the high voltage comes up. If the
high voltage comes up with the tubes removed, I would suspect that a tube
is conducting when cutoff bias is applied, and/or a fuse is open, or a HV
glitch resistor is open. One possibility is that a ceramic-metal seal is
bad and air leaked in, causing a 3cx800 to conduct on standby. Another
possibility is that one or both tubes have gold-sputtering leakage. A
high-pot. tester would provide the answer in a short order.

You don't have a schematic diagram?
