 Se> I'm in a bind.  The gradstudents before me goofed an purchased a 0 to
 Se> 24 Volt Power Supply (15Amps) to drive a Power OpAmp.  After close
 Se> inspection it became apparent the the OpAMp needs -12to+12V.  Since the
 Se> OpAmp drives a motor we need as much current as possible.

    Uh they didn't goof.  You see +-12v is no different to the
    motor as is 24 volts.  You need to make a virtual ground
    however.  If you don't need reversability there shouldn't be
    a problem.  Another easy solution is 2 0-24v supplies.  Be
    sure the power suppies can SINK current! :)

 Se> Is there a cheap way to convert 0 to 24 Volts (Floating) to -/+ 24
 Se> Volts.  The hard part seems to be the 15 Amp current requirement.

    Ussually is when you get above 10amps.  You could make your
    own :)
