But, relative to the problem at hand here, all that's needed is a
transformer. There's a bridge rectifier inside the RNC (Really Nice
Compressor for those who don't know), and that feeds separate regulators
for the positive and negative voltages required by the internal workings.
Compressor? Brick-walled Geoff! :-)

Geoff asked for the right thing - a transformer. And since he was
planning on powering three units with it, one that he could mount in a
box is more appropriate for the job than a wall wart with a single
output cable.
