So I got some working test equipment finally.
I found a pin on the crt that was very corroded. I cleaned it up.
Crt tester showed a weak gun so I followed the rejuvenation instructions and all 3 are now in the good range. No shorts either.
The color is better but I'm not sure what my issue is so here's a short video. I'll find something else to play later on.

The Color bar generator was fun to mess with.
So now I can test tubes and do a little more now.
