Russ: are there any other windings on the transformer? It there is a
low voltage winding you can actually wire it up with the primary
to "buck" the voltage and in essence subtract that amount from the
primary and the porportional amount from the secondary.

You didn't give any size specs so it's difficult to give a more
distinct answer. Obviously smaller supplies (up to about 250 Watts)
are easier to voltage adjust than a 4KW monster.
