If what we are talking about is the transformers, a transformer rated for 50 Hz
will work
fine at 60 Hz -- in fact, it will run cooler. The opposite is not necessarily
the case,
especially with large transformers.
Some AC fan motors might run a bit faster. I don't see that as a problem. I
can't think of
anything in an amplifier that would require 50 Hz and not work properly at 60!
