Can I use an original NES European AC adaptater on an American NES ? I believe specs are similar but that 50/60HZ thing bug me.
If the polarity is the same and there is available voltage range + 50/60Hz sign on the sticker I believe it can be used. << stupid me... you're living in Europe of course.
I'm using a Japanese AC adapter for my Twin which has specified input "100~~240V 50/60Hz" and it works beautiful here (230V / 50Hz).
As for me, it looks like it should be fine, just be sure about that polarity!
Is there any difference in the output voltage/amperage between European and American AC adapter ?
