I have a little cute CRT tube named 3Ð›Ðž1Ð˜ and I feel guilty of not giving it enough love. From what I know, it needs whereabouts of 500-800V on the accelerating anode, I don't think the current will exceed 100uA. I know how to make 800V from 220V with a regular isolating transformer and a diode multiplier. But I would really like to keep it small and wallwartsome, potentially nixieclockable, so I'm shooting for 12VDC->800VDC conversion. Maybe someone has done something of the sort recently, care to share your experience? I'm thinking of using an AVR to switch a trusty IRF630, like in a buck-boost converter, but with a switchmode transformer in place of the coil and feeding a 2x multiplier from the secondary. Worth trying, or there's a better way to do it?
