Jumping in here, (just registered, so HI-)...) I also have a SRM717 w Japanese 100v and I blew it on a cheap Chinese transformer smartypants me. I was planning to run it on US currency stepped down from European, but that isnt a good idea, or? It did work with another stepdown transformer, but that one made noise so..... I am anyways broke and my KGSSHV by Spritzer's Hephaestian Hammer Services arrives tomorrow (hopefully), but I'd like to fix that dear old thing dont I? Either to have or to sell. Any suggestion would be welcome
