I have this Setchell Carlson P65 I restored several years ago that suffers form this same issue. Same basic circuit and CRT type as your TV, although it is a transformer powered set. Sams shows 50vpp video going to the CRT. If I recall correctly I can easily operate this one outside the cabinet. Hopefully I'll be able to take some voltage measurements to see how closely this regulates sync pulse level.
