I think that John swapped out the caps in this power supply when he first got this machine and starting having problems. With all of the hybrid cars running around these days, I wonder if it wouldn't be possible to tap into the car's DC bus, attach an inverter and come up with an handy 25 KW or so 3 phase power supply. That might convince me that a hybrid vehicle could actually be useful. I think that some of these hybrids are running on 300+ volt DC bus systems. For now a diesel generator might be cheaper, but sooner or later these hybrids are going to be coming down in price as the gloss wears off and the vehicles age.
