RCA CTC-11 Purity & Convergence Settings

[Phil Nelson]

Now that I have the blue lateral magnet and purity rings, I'm ready to try setting the purity, convergence, etc., on my RCA-CTC-11. Except for sliding the new parts onto the CRT neck, I haven't tried to adjust anything, so I guess this will be my "before" picture.

My little RCA Color TV Service Handbook has a pretty clear description of the general procedures. I've heard different ideas about which to do first. Someone said, purity first. The book says set static convergence for the center of the screen, then purity.

Opinions? Any other advice is welcome, too. I'm assuming I'll have to do this more than once, so the first time will just be for practice.

P.S. I am using a new-ish solid state pattern generator.
