I still have a tendency to run off looking for the oddest possisble problem, need to remind myself to check the easy stuff 1st (deflection prob, check deflection tubes). I checked two caps (cardboard single sections 400v 10uf and 40uf) both tested very well. again a tribute to the caps used. I did see something odd. one of the doublers (the one with the grounded can) shows as a two section cap on the schematic. the one installed is a 3 section with one section cut off, the other section bridged with a separate cap, on one section active. Very odd, I will see if I can read the values off the cap, perhaps it was an early replacement.
On the HV pulse regulator, there is a 68pf cap that feeds the pulse from the horz osc to the grid of the regulator. I think I will scope both side of that cap and see what is there. I would be shocked to find a problem with that little cap, but the HV regulation is def not right.
