Another stress factor is that European generators run at 50Hz, like our
mains. Many mains transformers run much hotter at 50Hz than at 60Hz,
ripple voltage increases and induction motors run more slowly,
considerably affecting blower performance.

Very few US manufacturers are capable of in-house testing on 50Hz, so
it's good to see that Elecraft have placed a KPA500 with Brendan.
