I'll need to look at the vertical deflection circuit in the schematic but does anyone have any off the top of the head ideas what might be wrong with this?...other than a lousy pot! I checked all of the pots for ohm values and they all seemed to be ok but maybe I missed something.
The centering pots are elevated to deflection plate potential (about 2 kV)...is the vertical centering pot missing its insulting “knob” ?
