It seems the 36K control is shot. I get about 0 ohms at one extreme but after a few degrees of travel, it jumps to 500K and stays there. DeOxit didn't help.
It's an oddball control with a shaft running through it to the volume pot/power switch.
One good thing though is that only two legs of the pot are used so I can easily stick a fixed value in there that gives me a decent picture for now.
Maybe AUdubon5425 saved this control from his set
