    Looking at the schematics, I'm not seeing any reason that I shouldn't be able to use an external power supply and a speaker, and be able to test the sound board out of the machine? I can't seem to find any reference to others doing this though?? Since it looks like the power goes through a full wave bridge and needs +/-12, I'd think 25v AC in to the power, and I'm set.. Am I missing something dumb??
