Another long hiatus, then finally got back to the set today. Since I can't see where the pole pieces are in this rebuilt tube, I was thinking maybe the convergence coils need to be more forward. Turns out the opposite is true. After a lot of back and forth and turning the assembly to see what position has the strongest coupling, I got the red and green convergence nearly perfect. However, the blue horizontal is still not doing anything useful. Don't understand why not, but at least there now seems to be a definite pointer that it's only the blue that's bad.
