The Variac Method: Since cap reformation is usually an

power supplies, and the power supplies are specifically converting AC
voltages to DC, you can use the variac to supply the entire unit with
ridiculously low AC voltage and let the power supply figure it out for
itself.
Caveat being that it'll only work with linear supplies, not switchers of
course :-) (I know we're really only talking about linears here - but
just for clarity!)
