Original poster: "Mark Rossman by way of Terry Fritz <twftesla-at-qwest-dot-net>" <marossma-at-oakland.edu> Has anyone built an MOT power supple with an imput voltage of 240v with transformers that came from a 110 volt microwave. Im assuming that the primary windings could easily handle the higher voltage, but i thought id ask before i hooked it up. Thanks a lot Mark
