Transformer core can saturate if line frequency is too low. Except I’d be certain KPA-500 uses the same transformer for export to 50Hz countries so your variations are fine.
Many years ago when I was young & dumb discovered this the hard way. Customers would take products with 120v/60Hz line xfrs and run them in Europe 240V/50Hz with a step-down transformer. They would saturate, overheat & pop fuses. 73, Josh W6XU Sent from my mobile device > On Jul 6, 2022, at 12:51 PM, Dick Bingham <[email protected]> wrote: > > Greetings everyone > > I hesitate to use my KPA-500 here at this CN98pi QTH.
