> Hello. I live here in the U.S. & may be purchasing a G6 frame case from someone in the U.K. Can its A-100PSU2 230volts ac/50 Hz power supply be rewired to work at 120 volts ac/60 Hz, and if so, is there a schematic available to do that

The only thing I am aware of is this, which shows the older-style transformer:

It seems to suggest that voltage selection is made by soldered links on the back of the PCB, so the answer might be 'yes', but only if you *really* know what you are doing (note the document itself is plastered with warnings). And there is no guarantee that the voltage selection arrangement is the same on the new PSU2.
