the pot in the HV cage was a horz centering pot, so I adj that and re did the purity (rings and yoke placement).
I am getting pretty much a full raster now, I could get more by upping the horz bias, but as is its about 240ma with the CRT bias at min. Still have a bit of center RG vert issues top and bottom that I can't seem to work out with the convergence board. I am going to try replacing the Se 4pack with discreet diodes and check again. I checked the Se pack and was getting AC on them (and DC) so my guess is they are leaking when reverse biased. I assume this is not good for convergence. At least the purple line is gone.
