[Amps] [rfamplifiers] Re: Xmas special offer upadate( warranty and pictures)

[Vic K2VCO]

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!
