That sounds like you're back the variac approach, but like Jerry pointed
out, that variac knob is a point of vulnerability to visitors with
twiddly fingers (file under "kids who can't keep their hands to
themselves  :-)").  Maybe a fixed isolation transformer with suitable
taps to drop the secondary below line voltage just a tad?  Just thinking
out loud.  Don' know how many holes the idea might be full of. :)
