That did it! VCEN was the key!

Funny the service guide does not mention VCEN in its section on correcting geometry. Why?

Now I have the picture near perfect. It's still a little off, mainly in the lower left corner but I think I can live with it. I've never had a CRT TV with perfect geometry.

One minor worry is I had to adjust VCEN and VPIN to just about the extreme range.
