Good luck on the pots - all three were burned open on mine, and 2 of 3 someone gave me from a donor chassis were also. These are special 100 ohms tapped at 25/75, esentially unobtainium. It was a poor design since this is at the low end of what carbon comp pots can do resistance wise.

The problem is that the tap is used to set up a zero-current point so you can go plus or minus. The only way I could get it to work with an untapped pot was to use two pots with a toggle switch to select if you wanted zero to plus or zero to minus. It seems like it would be easier to use the convergence coils from a later set with the permanent magnets, but I think they are wired differently for dynamic convergence too, so won't just drop in.
