I've been searching for one of Bob Anderson's videos that had to do with a rebuilt crt. He showed how to measure cathode current at a given filament voltage. I would like to watch it again to refresh my memory but I have watched so many of his videos that I can't remember which video it was.
(Predicta video I think) I really enjoy his videos. Crt I want to check is a 14ATP4.
Thanks

Found it, Thanks for the great videos Bob.
