240 VAC 60Hz amp running at 230 VAC 50Hz - safe?

I have a new pre-amp which mentions on the back panel that expects a 240VAC 60Hz input.

In my home country the power supply is 230 V/ 50Hz.

Can anyone advise whether:

1. It is safe to operate the amplifier despite freq difference.

2. Whether the freq difference may impact / retard the amplifiers performance?

Thanks!

Depends on the transformer. 50 Hz is tougher to deal with and often requires derating the transformer if it's not rated for 50/60 Hz. If the transformer is oversized to begin with, that's not much of a problem. However, the problem is compounded by using lower voltage. The real question is whether the transformer will handle "single phase" as opposed to "split phase" without saturation, heat and noise and that's not predictable.

Thanks for the reply Ngjockey.

The response from the manufacturer on this question was

"..the truth is that all of our transformers are manufactured for 50Hz operation. It just so happens that they work just fine at 60Hz in the U.S. also"

Does this ring true?
