Along with checking that filter as suggested by Eric, also check to see if
the secondary voltages off of the flyback are close to be right on....

one gets rather warm also. The B+ is about 125 (I think or 135v), I believe
the timing on the collector pulse is 10us or slightly less(reading with
Sencore SC60scope) and there is no noise on the hor signal from the driver.
I do not have a schematic and am not sure where else to look.
