/diy/ - Do It Yourself

Hi /ohm/ ,
So i scrapped that old video crt intercom, the crt is pretty neat and i want to use it in some design project maybe a clock or some lissajous curve demo.
I want to get rid of the original pcb and rebuild the crt alim but i can't find a simple schematic to do it.
All i can find is electrostatics tube power alim (like oscillo ones) but this one has a flyback transformer..
I did found a lot of simple high power supply that can be build from the flyback transformer, so that might be a start, but what about the tube itself ?
There is 5 cable connected at the end of the tube, i read some 100v and 30v around them, so can i just use any standard 100/30v supply ?
(i just want to power up the tube so i have a light dot, i don't want the whole deflection circuitry)
Many thanks
