Also would like to sell these IGBT half bridges bricks. TSHMG75J2YS45: 600V at 85A continuous, but they do up to 800A in DRSSTC work. Max frequency is 105kHz. http://i.imgur.com/XBAAq.jpg Ideally I'd like to get back almost what I spent for them, ($150) but at this point I'm just trying to get rid of everything, so $100 for the pair.
