Ok, here's what I've checked. The focus output to the CRT is 4.3kV, which doesn't change with the focus adjustment. Junction of the 66meg resistor checks out to be 4.56kV.
I pulled the focus rectifier was running, the screen stayed lit. I checked the 66meg resistor, it was reading 64.5meg with a megger at 1500V.
Also, horizontal position pot is shot. Track measures 10ohms, but the wiper is intermittent. Cleaning didn't help. Any suggestions on a replacement? I can find ones rated up to 500V, but nothing over that
