I have a donor chassis as well, so hopefully I can get it right. but since the center is looking good I may be ok.

Don't mean to be a party pooper, but the dynamic convergence circuits in this chassis are AC coupled - so when you move the edges up, you move the center down, etc. Some point about halfway to the edge stands more or less still. It's an interative PITA to get both static and dynamic. Start by doing dynamic to get lines to be parallel, then do static, and repeat.

Doing convergence on the production line for those sets must have been a nightmare. One thing manufacturers hate is having to fiddle with product, they prefer it if they can just stuff circuit boards and have it work with no adjustments. SAW filters in TV IF strips was very nice, no alignment needed.
