    Greetings,

    My family and I will be moving to Japan (outside of Tokyo) later this year. Power mains are 100V/50Hz in that area. I plan to buy a step up transformer to increase voltage to 115V (ACUpwr or something similar), but have no way to convert 50hz to 60hz. I have a SP13 and PH16 I'd like to bring with me, but am unsure if the supplied transformers are the 50hz/60z variety or only work with 60hz. I'm not at home (and won't be for two months), so I have no way to go and look or test them anytime soon. If anyone knows off hand that would be great, if not, I'll wait for Roy to return from vacation and ask him. Thanks much,

    Matt

    Get the line voltage difference sorted; the AC line frequency will not be an issue.

    Yes.

    60hz transformers will operate very slightly less efficiently at 50hz, but not so much as you will notice it in actual operation.
    What you will notice are the green-with-envy looks from visitors.
    Be careful of the Far Eastern cultural peculiarity that if you brag about an item you own based on the admiration of another, you are very nearly obligated to offer said item to that person (no, I am not kidding).

    Be modest - it is nothing, nothing at all....

    I would say 50 Hz works LESS efficiently than 60Hz, but try it with 120vac in and go to 125v in if need be.

    I thought Japan and most of Asia were on the British 240 VAC setting.
