MOTM

Id advise against this.
 
The a112, being a digital module, probably works on +5v.  Id imagine its
regulated down from +12v anyway, and the extra voltage at +15v may be enough
to overstreatch the regulator / heat dissipation, etc.  Failure may not even
be that quick.

Julian (who has an a112 in his rack, but cant look at the pcb without a
screwdriver...)

I can't imagine there's anything in this module that would be too
demanding of exact power supply voltage, Paul. Set it up with a
-12/+12 supply to watch proper behavior, then give it -15/+15 and see
what happens. It surely won't blow up. Most designs will work with
either voltage with little if any modification.
