I'm not sure, but I think you might be able to buy a variac. (Variable output transformer) Van Halen used one to drop his voltage a bit. You could get one that is made for 220 volts and then twist the knob on top to drop it down to 110 volts to make the Mark V work, I think. I'm not entirely sure though. I hope someone else chimes in. If it does work it would be a hell of a lot cheaper than actually buying another power transformer and then having a tech change it out.
