USA Onkyo receiver at 100V 50Hz ok?

Hi,

I'm thinking of taking my Onkyo receiver to Japan, and I'm wondering if anyone knows how the different electricity will affect it. It's designed to work with 120V 60Hz, and in Tokyo they use 100V 50Hz. I've heard that some transformers may saturate if used at a lower frequency, and that they may also overheat if used at a lower voltage.

Does anyone know anything about the transformers used in Onkyo receivers, and whether they would have these problems? Or even in general whether the small voltage difference or frequency difference would cause problems for a receiver? Thanks for any info you can give me!

Jeff

You will have to use a transformer to step up the 100 VAC to 129 VAC. If the receiver's power supply is not rated to work at 50 Hz, the power transformer is going to run on the hot side. Depending on the design of the power supply, there may be some filtering problems.

If you are using the receiver section to get radio stations, take care about their station allocations, and broadcast standards. I know that some European countries are different that here in North America.

Personally, I would sell the receiver, and get a Japanese one over there. This will avoid a lot of problems. You may end up with something over there, that is useless.
