I replaced the two HV resistors and the 4uF video amplifier feedback capacitors. Checking the old ones found the resistors out of tolerance, and I never could get a steady reading off the 100MEG one. One of the capacitors also was bad and it was the one in the red video amplifier. Now I have normal range on the static convergence control, and the video amplifiers are back to normal. I'll have to do a lot of tweaking to get the convergence better than it is now, but I think I can get it close. I am having trouble getting good purity, on these sets there is a lot of interaction between purity, convergence, and focus. The video looks pretty good and if I run it a bit dimmer than a modern set like it should be it actually look really nice so in the absence of an actual CRT test I will declare this one to be good. I think the convergence would be considered OK by an average person who doesn't work on these.
