I've been blessed!

The convergence wanders a bit over time, and I think some red misconvergence is visible in some of the Rose Parade shots - tweaking it could be a lifetime hobby.

I found that fine adjustments of the position of the convergence yoke help, as well as the controls themselves. The R,G, and B should be independent, but they may not be perfectly so. I moved the convergence yoke back and forth until I got the maximum effect, and also tried rotating it slightly left and right for the best overall result. I think the rotation helped get it aligned for minimum interaction between R, G, and B. Mis-rotating the blue lateral from its nominal position can also affect R and G.

By the way, my set has a blue lateral magnet like the CTC-7, not either the CTC-5 DC coil or permanent magnet. It looks oddly crooked with respect to the gun structure when mounted correctly.
