Miller & Kreisel LFE-4 Bass Controller - help..

Hopefully someone can help me.. Picked up an MK LFE-4 Bass Management Controller; although don't have the power supply for it..

It requires 18vac according to the chassis; just not sure on the current draw.

Does anyone have an LFE-4 or even a BMC-1? What are the specs of your power supply?

I'd imagine 18vac @ 1amp should be sufficient; but just want to be sure it's enough..
