Original poster: "Tim J by way of Terry Fritz <twftesla-at-qwest-dot-net>" <digital_raven45-at-hotmail-dot-com> I would try using Microwave Oven Transformers in series for a power supply. Try 4 in series with the middle two grounded with two floating! This should give you around 9.6 kV -at- 600 mA to play with! ....one mistake with this power supply and your DEAD!! Be careful!
