SB is right, that was discussed as well.

all the usual suspects were check or replaced some more than once.

the two 1.5 meg resistors check and replaced
the .0033 grid to K disc cap, replaced SEVERAL times
the HV pot checked for operation
The .1 Filament to chassis, replaced.

when he said he saw sparking around the heater that is what got me thinking to check heater potential. Voltage checks should give us the answer.

I sure hope this is it as I am out of ideas.
