Well, I'm working on resurrecting a 6100 in my Star Wars. It actually does work, but the screen size is inconsistent, blooming on bright stuff more than I think it should. I just recapped the HV board, with slight stability improvements (screen doesn't blank out randomly any more). When I opened it up to install caps, I was surprised that the thing worked at all. The 33uf cap was bulging badly at the top, and a couple others showed signs of leakage.
Anyway, after replacing the electrolytics, I went to adjust the B+, and I found that I can't. It's reading 244 volts, and adjusting the HV adjust knob on the HV board doesn't change it. It also doesn't change the picture any.
So far, I haven't done anything to the deflection board, but I'm going to start investigating the HV cage more closely.
Any pointers?
