When you change the fuses, you insert the fuse holder so 220 is visible in a
little window instead of 115. That changes the wiring to the power
transformer input for 220 volt mains operation. It's described at the
beginning of the Owner's manual.

I meant to say change the fuses and reconfigure the fuse block... I was

So switching the fuses and changing the
That is correct as far as changing between 115 and 220VAC mains goes, but
there's a little more to it than that. The power supply is not regulated, so
its output can vary depending upon the actual mains voltage supplied within
the nominal 115 or 230VAC ranges.

A hollow conductor is not analogous to a coaxial cable. It has no
