CTC-7: Convergence, Convergence, Convergence

[kx250rider]

Typically the dots aren't round, due to various SLIGHT tuner and IF problems, and also due to slightly weak CRT or poor video response. Try turning the contrast way down and see if they get more circular. Also, if the TV focus is off, it will malform the dots. But no matter what shape, you can still use the dots for convergence purposes. They just need to be sharp enough.

As far as placement of the components on the neck, you need to refer to a diagram. I could try to explain, but a printed diagram is better. I'm not sure what effect on the generator dots mis-installed neck components might cause, but I can say for sure that those things need to be right in order to get convergence and purity. Any of the RCA factory manuals, or the Color Pict-O-Guide, or any early color TV repair textbook will have a diagram.
