That looks really good !

I'm wondering about the blue dipping on both ends at the edge of the screen.....
Could the zip tie around the convergence magnet assembly be changing it's
orientation from a perfect perpendicular to cause the dipping....?

Imagine if the magnet was forced towards the back of the yoke, and not
straight up and down, then if it is trying to make the line straight, but
orientation is wrong, pushing the line lower on the ends.... If the magnet's
orientation was forced away from the yoke would the line go up at the ends
if it's all working correct....?

Or am I all wet, and it's most likely a aging part, or the best it's gunna get....

The three coils on the convergence board are blue line adjustments. One of them (I forget which one) is for the horiz blue line.
A word of caution: one of those , if you back the slug out too far, will roast one of the pots. So go easy.

Thanks for the warning. I started my first convergence by trying to center the convergence adjustments. I need to replace a ferrite core in one of those coils, so the convergence you see now is just enough effort for testing and fixing the rest of the set.
