Hello, a friend of mine found what probably is an US 1541 drive since it is
powered by a 117V 0.5A power supply. Its board P/N is 1540050 and there are
many "patches" (I think these are official upgrades).
But the problem is that, here in Italy (and in Europe) the power is 220V. So
I have compared the 117V power supply and the 220V one from another drive
and I noticed that, on the 220V one, the FUSE is connected to a red and to a
black piece of cable and that a black cable is free. Instead, on the 117V
unit the FUSE is connected to two black cables from the PSU and the "free"
one is red.
So, if I exchange the cables connected to the FUSE holder, can I
successfully convert a 117V unit to 220V? If yes, should I change the 500mA
fuse with a 250mA fuse like an European drive?
Or a drive modified in such a way will definately be like a bomb? ;-)

P.S. the PSU P/N is the same but the 117V one ends with "-02C" and the 220V
with "-03C".
