Any danger of running a 100v unit on 110v ?

I realyzed that my unit have a small sticker on the voltage that says 115v but the "real" voltage is 100V. The unit works pefectly but I am just wondering what might happen.

Let me know,

thanks

If it has a sticker on the back then that is the correct voltage if the amp was bought through EIFL or somebody similar.

It was bought in Japan. It has a hand written sticker that says 115V but underneath there is a black one that says 100V. And BTW, it works great. I was just wondering about long time effect on the unit.

Thanks

Thanks Spritzer. I have a version with the 3 pro-only output in the front. I think that I may have found an answer...

I am the third owner so I don't know the exact history of this unit. My Stax definitely came from japan. I have the box, but the previous owners scratch the stickers on the box and I cannot see who was the seller anymore. From what I can still see on the box, it came from Japan. I guess it was a modified version from EIFL or someone else in Japan. In any case, it works fine plugged in the 110V so I guess that someone must have converted them.

Just out of curiosity, what would happen if I plugged a 100V unit in a 110V socket ? There is a seller on eBay that claim that 100V unit can be connected to 110V (but he still recommend an adaptator)...

Thanks again for your help.

I have a 313 from EIFL and it has the 100v Stax sticker on the back and a 230v one as well that EIFL added. They changed the voltage configuration a few months after the normal bias was finally discontinued so yours might have been bought in that gap or EIFL can still convert the amps, just don't know.

When you use a 100v transformer with 117v(or what ever your line voltage actually is) all the voltages on the transformer secondary will be more then they should be. Transformers work on fixed ratios between input and output voltages so when you increase the former the other increases according to that ratio(3:1, 1:10, 1:15 etc.). Basically all voltages, including the bias, will be too high and some amps can take it, while others can't.
