[Electronic M]

Thanks Zeno. The fuse was the first thing I checked. Subbing the module with the newer known good one(I've seen it work in the parts chassis) yielded no change. I also tried a spare CRT and yoke from a non-zoom CII and that didn't change anything either.
I think my next move is to troubleshoot the main chassis.

Jr tech I believe it's the current strain of COVID but I have no clue what other pestilence that masked thing was carrying. By the time you've read this my ear will have been like this a week. There's been no significant change in me since Thursday when the heavy congestion that messed up my ear ended...ma at least in the last 2 days started not feeling bad enough to be worried aloud about dying so that's a relief...
This reminds me of the last time I had COVID....It hit really hard for a while, mellowed some then wouldn't let go for a long time then faded out. As something of an audiophile having the balance control of the left ear messed up really makes me sick... not to mention dizzy.
