I'm not quite sure where to find three isolation trannies at $50 each- tell me the secret! You're right, that would certainly simplify my situation. I could use a non-isolated, half NST followed by doublers, but the problem there is that while I have fewer stages, I have to have higher-voltage more exotic parts. The microwave transformer allows the use of the microwave caps and diodes. Yes, it's a tad bit dangerous. Do you have any pointers to x-ray equipment liquidators online? Certainly the power demands are not too heavy here.


>>>I wouldn't fool with microwave oven transformers or the like... How much current do you really need? Aside from a surplus Xray unit (the best solution, probably), you might do better with some 15 kV neon sign transformers ($80 new) and some 15 kV isolation transformers ($50 used), which will give you 45 kVRMS, and near to 60 kV rectified and filtered. Add another NST and a pair of isolation transformers, and you're up to 80 kV.
