I have built a pair of electrostatics using Sanders' book. I'm having trouble building the permanent high voltage power supply. Right now I'm using a professional, loaned power supply which costs about $2K more than I'm willing to spend.
I plan on using a step up transformer (400-500Volts) and using capacitors and diodes to retify/multiply the voltage up to 3KV DC. The plans are all laid out in Sanders' book, but I cannot find a step up transformer that is sufficiently cheap. The bias draws almost no current, so power is not a problem. So, can anyone help me find a cheap (<$30) transformer that steps the voltage up to 400-500 Volts (given 110V at 60hz, of course). The current rating can be less than 10mA.
Thank you very much.
