I sorta want a CRT tester, probably woulda helped with that RCA I did back in Jan-Feb. The set works okay but has a weak jug. Goes silvery when you crank the brightness and takes a good while to get bright enough to watch. It still makes a watchable picture with the lights on so I can't complain too much.
As for Shango's methods, I aint even mad. He's able to do quick and dirty diagnosis without a shotgun recap. I've learned a bit by watching his channel. I usually fully recap my sets because I only have a few and I like to use 'em, also sometimes it just fixes mystery problems so I don't have to diagnose
