First open the box and see if it uses two (full wave - two hots and a ground
off the transformer secondary) or four (bridge - two hots off the transformer
secondary) configuration on the rectifiers. If it uses a full wave rectifier
setup you can double the voltage and halve the current by switching to a
bridge rectifier.

If it's already using a bridge it might be possible to use a voltage doubler
circuit.
