Some other thoughts:
Your CRT Socket looks horrible, IMO this set is worth finding a replacement. Pin 11 (Blue Cathode) and pin 12 (Blue Grid) are the ones that look the worst, Pin 9 (Focus) actually looks ok, any greenish residue there? How does the focus pin on the CRT look? Like you found the tie point on the HOT frame is a great place to measure focus. Looks like the original Horiz Out Transistor and HV Trippler, always good to see that. Yes. 4.5-5KV for focus.
Module pins and the Service Switch almost always benefit from a good cleaning.
Best outcome depends on stable and clean 125v, and 24v DC supplies, and the 240v Boost supply. The boost filter capacitor C270 10uf is always a good bet to replace.
I wonder what it was like to deliver and setup one of these back in the day....
