Original poster: "Jim Mora" <jmora@xxxxxxxxxxx> Hi, Does anyone have a Maxwell 37677 that hasn't been over-volted that they want to sell? I need a third one as the base of a fullwave voltage doubler to be powered by a 15kv/120 NST pair and variac. The next 2 stages are 4000pf big door knobs (this should add some punch to the current output). Thanks, Jim Mora
