Re: Home Made Variac



One idea I've not seen expressed here is one I used for variable line
voltage as a kid.  I would pick up those military surplus plate or filament
transformers with the tapped primaries and us it as an auto transformer.
Worked pretty well for a long time.  Had one built up with a rotary swithc,
meter, fuse and outlet for bench use all through high school.  Back in the
dark ages.
