Have you verified the meter? Try it on your wall plug to see if you are getting about 120VAC.
If the retrace cap is low in value, the HV and filament would be high.
I don't recall the pin numbers of the filaments, but they should read very low ohms (power off) across the filament pins (couple of ohms) if you are on the right pins.
Since sweep is regulated, the voltage will be the same hot or cold.

Hey John,
Yeah the meter gets calibrated everyb6 months for my works IDK certification stuff, I set it to AC for sure, I even did it again after watching a movie a couple hours later just to confirm.
The pin numbers are 9 and 10. I measured across those.
I also included pictures from the manual of the circuitry and board.
I feel like I've clearly done something wrong, but I don't know what it is.
