Re: [TCML] High voltage diodes



Oh I forgot to mention, any good suggestions for current limiting here?
30ma is far too much for a VDG am I'm sure most of it's going to be wasted
anyway. Do i need a good old variac or some other cheaper alternative? Will
a light dimmer really work i this situation?

Thank you!
