The problem is in the hv circuit as it's related to the lamp thru the heater tap/plate connection. If you are sure all of the caps are good I would replace the rubber wire in the hv and heater circuits. Slim chance that you may have something like a shorted primary winding on the output transformer. Could have a tube w/a short that is pulling the hv down.
Happy Hunting!
