I have two 0-140VAC/4.5Amp variacs that someone gave to me that I'll probably never need. These are open frame units, used, untested but appear to operate smoothly, with knobs and dial plate, made for panel mounting. If anyone thinks they could use one or both, the price, if you pick them up, is free. If there are no local takers, I'll take $5 plus shipping charges. Contact me off-list please.
