Panels have a S-##### number that may have a sub. I can look those

Kicks the can down the street. Gives the cust time to save up
the $600 +, a LOT of $$$ back then. Using a modern B&K
or Sencore is best on clean & balance. Heavier settings are
last ditch. Results seem best when you get lots of needle swinging
& flashing in neck. Unpredictable but can stretch things a few
years at times.

From what I read online the filaments of the older CRTs from the 60s and prior tended to be thicker and more rugged due to the filament being thorium based. I definitely saw quite a bit of sparking and flashing when doing the rejuvination at the time. It was a situation where I had nothing to lose because this CRT clearly had been used ALOT and the chassis's dirtiness testified to this. I always wonder if there would be any money in rebuilding old CRTs again, i mean if someone got into that business they would be the only one in the whole world doing it.
