I have always wanted one ever since I saw one of them in HS, and it blew me away how it worked, so I finally gave in and got a couple, cheap.
First one seems really clean looking, seller said it is working, which I doubt, as there's something missing in this picture.

This one HAS the missing part, and 2 templates, but said was unsafe to use as it was "smoking",I spotted something odd in the picture.
It came today.
I was correct, I did spot something..

Not even sure if this CRT is good or bad, It's an odd type, not sure how to test it, does not match the schematic.
Now I wait for the other one to come.
