Well I got one NOS Zenith 22-5001 and three Genuine NOS 1600 volt Orange Drops from 1979 so I installed all of them in place of the old white tubular caps and bingo, I now have a reasonable 26kv at the anode.
The picture isn't pulled in on the side anymore so probably the extreme HV was shrinking the picture before.

The set still has issues, the tint range won't stay put, something on the Chroma board is loose or dirty, it changes when I mess with it, also has some video smearing which might also be dirty connectors on the modules, the board connectors always were problematic on these sets even thirty+ years ago, we used to just solder them to the pins during service calls to make sure we didn't get a call back.

This whole set is very dirty so it'll probably get a total teardown and cleaning at some point, the only way to get the cabinet clean will be to wash it in the bathtub.
