I'm waaayyy otta range. And G2 was already at minimum. I'm going on a theory that since I had at least one open HV safety cap (and elevated HV) that this issue was "masking" a focus divider that wasn't putting out what it should. Now my focus voltage is too low and the "best" (terrible) focus comes at the highest focus pot setting. Prior to the new safety caps, it was dead center and the pot is still controlling focus voltage normally. I ordered a new triple/focus divider and if I'm wrong, I guess I have a spare for another CCII.

*I also checked a big 500Ω sand resistor attached to the triple and it read 506Ω, so well within spec
