I got a free one to use as our church DJ mixer, but no power supply.
I have an electronics type friend who makes sequencers and analog hardware,
he can rig up a standard power supply to get around the annoying "proprietary"
power supply connection ... if we just new the Voltage and Amps of the thing.

if you have one, could use those specs..  youd be helping out the DJ ministry
at my church...
