No light on the screen though. How do you check the HV on one of these 3KP4 tubes?

I think I just used my 30KV HV probe and looked for a little on the bottom end.y fluke only does 1KV, and my older meters only do 1600V...

Any of the crt base pins, except for the filament, will show HV? According to the schematic the HV is 2.5K. There’s no traditional donut shaped flyback on the tv. It’s like a large adjustment coil winding
