If you look in a big ole black & white TV you will find some great HV
diodes. They are rated at perhaps 60KV and can handle about 500mA peak. I
got for out of the rectifier for an old 17" thompson TV - the whole
rectifier circuit was seperate... diodes, caps, everything. The caps were
huge, about 0.5uF at 40KV, too big for TC usage, but fun for discharge
experiments. I also used the transformer for a flyback device... TVs are
goldmines!!!
