Re: Variac fix
Looks like one side and the wiper was pluged in and caused the wire to
burn up. I don't know how many turns are burned but you may be able to strip
the turns off till you get to the good ones. That is if it's jsut a few
turns like it looks. If not you might have to rewind the whole thing.
