Ok I’ll need to examine the schematic and look in the HV cage at its condition. BTW I built the yoke housing support you showed and tomorrow I’m going to bring up the unrestored chassis on either a dim bulb progression or on my Sencore isolation transformer/Variac to see if it produces anything on the 5” tube. After that, I think I’ll try doing it with the restored chassis and see if I can figure out what to do for the video/sound misalignment. If I can replicate your bench top rig without blowing 15KV across my chest and heart I think I should be able to align it. I have test sockets for all of the tube pinouts so working under the chassis should be at a minimum.
