Seems perfectly happy at 110v still holding at 23-24kv with reg current down to about .9ma, HOT current dropped to just under 200ma at the reduce voltage.

That was with the shunt grid resistor jumped, without it, the max HV was 19k and the shunt tube was 1.3ma at the reduced line voltage. I hope to pull the chassis sometime in the next few days to do a proper check/fix of that and also check/replace any other faulty caps (like that video amp cathode bypass cap.

Just trying to decide best way to pull the chassis, will have to make notes of lead dress etc... as there are wires all over the place, tied back to various points, a lot using the CRT mounting for tie points.
