counts volts on fingers and yes. Only about 4volts RMS, you're perfectly right. should have done that before, So, how are we going to get the best out of a stereo amp; biamping? Or just assume one side not working doubles battery life?

Maybe it's a good idea to reverse engineer the power supply of a common Behringer or Mackie mini mixer to adapt it to 12V. You can't buy the parts to build one as cheaply.

Is there a mixer in Behringer's line of Mini devices? Those are very compact, but I suspect they all run off AC wall-warts. The BEAT800 phono preamp/beat counter uses a 1/2 wave rectifier to produce + and - rails from a 9V AC input. You might get away with substituting +12 and generating -12 or so with a DC-DC converter, if sharing a DC common with the power amp and other stuff isn't a problem. Otherwise, maybe an off-the-shelf DC-DC converter (isolated), or replace the rectifiers with faster ones and generate transformer coupled 9VAC somehow.
