Blowing up isn't quite the right term, but it is possible for the Famicom to burn out  -- maybe not the best term either -- if you use the wrong power adaptor. Some have argued that using a power adaptor expecting 110v in the US, which is 120v, could be a problem, because the Famicom will slowly fry. I've heard that isn't true because the Famicom has a voltage regulator that can handle it. I use a power converter that I place between the outlet and the power adaptor that lowers the power to 110v 100v (I have a Japanese power adpator) -- so the Famicom doesn't have to.

I use the one in the pic on this page:

The NES was a US release, so it'd have the proper regulation of 120v for US use. The Famicom was a JP release, so it'd have the proper regulation of 110v for JP use; hence, the need for conversion in the US.

DO NOT USE YOUR NES ADAPTOR WITH YOUR FAMICOM -- that'll make it "blow up."

Correction: You have 110V, which is a Taiwanese Famicom. Japan's is 100V. So, you'd need a different converter from the one I linked. TPE Famicoms don't pop up very often, so that's why I didn't immediately notice the voltage difference.

Taipei -- the initials used to identify where the Famicom comes from. Japan Famicom items are mostly HVC (Home Video Computer) or FMC (FaMily Computer). Taiwan Famicom items are TPE (TaiPEi). And Hong Kong Famicom stuff is HKG (Hong KonG).

Reread earlier posts.

US is 120v. So, you'll be pumping an extra 10v into the Famicom. Remember, the Famicom has a voltage regulator and should be able to handle the extra 10v, but it's your choice to convert or not convert.

Well, you should be able to look at the bottom of the Famicom. It should say HVC and that's it, or it'll also have TPE or HKG. Sometimes the code looks like this: HVC-001HKG.

And I can't help with the converter...try searching on Google. It might be the case that because 110v is so close to 120v, they might not make converters for that.
