Original poster: "Matt Skidmore by way of Terry Fritz <twftesla-at-qwest-dot-net>" <fox-at-woozle-dot-org> there is someone on eaby selling many variacs with drive motors on them for $40-$60. these are 0-180v at 20 A. using 120v in. what would happen if you ran 240 into it? anyway to pair these up to run 240? or even better 240 at 40 amps? -matt
