Burke,

There are exceptions to everything, but in general, wall warts are not a 
good power supply choice.
For most of the 12 volt wall warts, the no-load voltage soars to as much 
as 17 volts and when loaded to full rated current, the voltage will sag 
below 12 volts.

Now, if you can find one that is well regulated, it *might* be OK, but 
it has been a long time since I have seen regulated wall warts advertised.

Most wall warts are designed to be used with equipment that contains an 
internal regulator and filtering.

I would suggest looking for a 13.8 volt 3 (to 6) amp power supply.
