Will try cleaning pots again. Original fly was shot. On the advice of Nick Williams I pulled the flyback out of a spare 630 clone set I had and threw it in. Putting out plenty of HV for the set and I can adjust it with Horiz drive control from 9kV to upwards of 14kV. I have it set on about 10.5kV, the mid range. Stays cool and raster is stable overall. Now the yoke might be a different story. Have not tested or messed with it at all.
