No problem, I've often noticed a couple of things you should know:
1. Many times the pots are plastic. Be careful when you first "break" them
loose, I've ruined a few in Trinitrons which were stuck so hard the thing
kind of fell apart when twisting it.
Yes indeed. Fortunately this one wielded under my trimmer and all is
properly aligned now. All I need to do now is troubleshoot the keyboard
circuit which I hope is the same as the VT102...
