What type of wall wart does this unit use? IIRC, it was 12 volts DC
out; but how many amps was it? (Or watts, if thats the way it's
marked...)

Thanks,

PS: For a short time, I owned one of their previous noise units (don't
recall the model number; but I seem to remember it was a *heavy*
feeder. Lots o' watts!)
