Original poster: "Aaron Aab" <striker754-at-earthlink-dot-net> What is the best way to make an adjustable CHEAP ballast for a microwave transformer stack? My stack draws 140 amps, and while that is fine for drawing an arc, each leg of the 240V circuit is overloaded and going to trip. The one has twice the amps the breaker is rated for on it! Any cheap suggestions? Aaron
