You do not want to get in to re-engineering a switching supply! Get a step

Yes right Jerry! That's exactly the kind of answer I first gave to my
friend...but then I thought this (it is only a supposition): the "same"
amplifier is sold as well in Europe...now maybe they designed it such that
there's only a couple of components to change...I don't know and yes, even
if I didn't deal with them, I can suspect that switching supplies are
bad..

I would look at the circuit board for the switching power supply. I
would look for a jumper that
has two possible settings for 110 or 220 volts. I would also look at
any stenciling on the board
that says 90 to 240 volts or something to that effect. If I didn't find
anything like that I would use
the transformer as others have stated.
