Testing 7” Electrostatic CRT’s

I have a Sencore CR-70 and it does a pretty good job of testing Electrostatic CRT’s but sometimes it will show weak emission while the tube looks ok, other time’s it’ll show strong emissions and the tube will show a washed out picture, so here’s how I test them now.Super easy and shows the tubes true condition every time.
