more from Timmy

with the voltage divider in place but not attached to the filament he get 180v
attaching the filament drops it to 90v, not right.

the filament string reads infinite with a ohm meter (disconnected from the voltage divider) yet when connected drops the voltage.

I advised Timmy to disconnect the .1 cap, as its the only thing that is connected to ground and the filament. The cap replaced but could be the issue if it leaks when voltage is applied. I assume Timmy used a 630v cap for the replacement. FYI I always check new caps going in for value AND leakage at rated voltage.

Timmy understands that the voltage at the 180k/150k should be 180vdc and SHOULD NOT DROP when the filament wiring is attached. All the test where conducted with the shunt tube out of the socket.

Timmy please confirm the above esp the test were conducted with the shunt tube out of the socket (and I hope the horz out tube out also, so you dont have to worry about HV being produced).
