DAve, some guys have replaced those with diodes and got great results, while others (like Phil) wanted to shoot the set after all the work that was put into it. I've only changed them on one set, and while it did indeed make a difference, it wasn't quite enough for me to be satisfied completely.

Roundie convergence isn't always easy. Some have commented that you're never going to get it perfect... just to do the best you can focusing mainly on the middle of the screen. Anything better than that is icing on the cake.

If the blue is off 2/3 of the way down the screen, I'd try changing those diodes and possibly the caps (especially if they're old tubular caps). It's certainly an easy job to change that stuff out... it's not like you have to tear the whole set apart again.

But, before you do that, just for shits & giggles, try taking that blue magnet out, spin it around 180 degrees, and re-insert it into the assembly. Then start over with all your adjustments as per the instructions and see if that makes it any better. Sometimes spinning those magnets around is all it takes.
