This is what I have so far:
I touched up the static convergence, grayscale is not too bad, and it seems to track ok, dark to light. Its needs a good patient set-up.
The picture came up initially, pulled up from the bottom. I can adjust the Vert Size to fill the screen. The Vert Linearity is off, stretched at the top. When I adjust the Vert Lin, as I approach a better overall linearity, the Vert Hold becomes unstable. I pulled the Vert module, cleaned the pots, transistor sockets, the module connectors, re-tensioned the connectors, and put it back in. The Vert Hold is better but I'm still stretched at the top. Its not drifting at all.
I'm having a hard time getting the contrast down without having the brightness up too high. The contrast control acts more like a brightness control. I'm using a Sony DVD player and I wonder if I'm driving this too hard?
The HV comes up right away to 25kv and then over 30min it will very slowly gain another 500v and then stay stable. I have a really good focus point with the focus control about mid-range, but I have to wait for it to settle down to adjust it. Nice crackle on power-up, totally quiet after that. Horiz hold is rock solid.
So, plenty to work on...
