Gentlemen,
I have since fixed this chassis, but maybe this information can help someone who experiences something similar.

I had a K7000 that I knew worked, and I put it on my test bench to test it one last time before selling it. Anytime I put a random chassis on my test tube, I usually just use a twist nut to connect the dag wire on the tube to the grounded wire on the neck board. However, this time the wire slipped out of the nut right before I turned it on. Hit the switch and resistor R301, which is the big white ceramic resistor mounted on the side of the chassis, went up in smoke. It also cooked the filter capacitor (C55). Replaced both of those, and we are back in business. :)

that was the one that got blowed up by a bad white knob. I'd like to redo my primitive patchwork on it, then I think all it needs is new neck and deflection pots, plus whatever else went bad. I think I sourced R301 off it already too.
