I could use his help right about now
 Replacing the drive control has stopped the fuse from popping. It appears to be tin plated but I couldn't really see any whiskers.  All the resistors and capacitors on the HOT have been replaced and DC voltages seem reasonable. The cathode waveform matches whats shown in the service info.  I've also tried swapping out each of the the three tubes inside the HV cage, but the low HV issue remains. Only about 6.5 kV under load. Just for the heck of it I installed a full size CRT, and you can see how dim and unfocused it is.  So it seems to me that leaves the two high voltage ceramic caps inside the cage, the yoke and the flyback as culprits
