I powered the set through my variac and tried different line voltages and read the HO current. Here is what I got.
At 125V the HO current was 225 mA. At 115V it was 200 mA. At 110V it was 190 mA. The picture didn't change much. I decided to add some dropping resistors in series with the line input. I used four 8 ohm 20W resistors in parallel and mounted them to a terminal strip and the line fuse on the top of the chassis in an open spot. That dropped my 118V down to 111V which gave me 190 mA HO cathode current. The raster fills the screen and I have 25.5kV high voltage. I'll settle for that. Dave
