How to light up a Crookes tube?
I don't know if this is the right place to post this, but it is kind of related to TVs, so...
I found this "Crookes tube" and i want to test it. It probably still holds vacuum. The big question is, what voltage should i use? AC or DC? Someone thought about 2kV, and if they is right, may the focussing lead in an old B&W computer monitor be a usable supply?
