Hi Chris,
Thanks for the pointers. As you can tell I have very little experience working on color, or even b&w TV's. I went to school for some of this way back in the early 80's, but unfortunately was never able to apply any of it until becoming interested as a hobby. Now it's like learning all over again, and I'm a pretty slow learner unless I can put things into actual practice.
I understand the lack of dynamic convergence issue on the jig, I just didn't realize how dramatic it would be without the adjustments. We're talking horizontal color separation of 1/8-1/4" at the outer edges.
I made my own CRT adaptor, CVL and Yoke programmer. My CK3000 came with a 1990/91 supplementary setup manual; they actually have the Yoke jumper connections listed for the various inductances in the back of the manual. For an YP12 (12.6 mH) I have pins 1&7 and 2&3 jumpered.
Setting up this test jig has been a good learning experience in itself. I even accidentally found out that I can run my 21FJP22 without the CTC-11 convergence board plugged in. It looks very similar to the test jigs very poor convergence.
