PRI is the same as input and SEC is same as output. The symbol that looks like a line with three dots under means DC so that's good. What is it that you don't understand about the FAQ? You'll have to check polarity of that adapter too.

Since it doesn't say anything about polarity I suspect it's one of those were you can switch polarity yourself by turning the plug.

It was more a fear of "it looks okay but..." the end of the plug has changeable pins with the +/- option printed on the plastic of the barrel.  There's no other switches or buttons to change anything else.

Get this one :)
I always downshift near a hybrid, so they can hear me hurt the environment...

I'm in the UK so I'd need another plug to convert that to work! I could get a Mega Drive/Genesis one but those are about $20 and I have the one pictured which I was hoping would save me some cash.

If everyone just posted "Just to be sure, is this adapter OK?"-questions all the time the FAQ would be pointless. A few such questions is good as examples for others to read, but I think they are starting to pile up now.

I can say that your adapter is good to make you feel at ease but I probably don't know more about it than you do so it's just false safety, it's better to make sure that it works yourself. The best way is to check it with a multi-meter, you can check that it really outputs 9V and that the polarity is correct. You can google how to do it, it's super easy really.

About polarity, the AV Famicom needs center negative so make sure you (or someone else) don't put the plug the wrong way. And finally, yes that adapter looks fine to me.

I like to think that for every "will this adapter work?" post, there are two or three people for whom the FAQ was adequate and didn't end up making a post about it.  You know?  I think that without this FAQ, there would be even more posts like that.

And I'm not saying this to knock people who ask questions -- you're better off asking than blowing up a Famicom.

You are probably right about that. Or maybe even worse, without this FAQ more people might blow up their Famicoms.

The FAQ doesn't mention the AV Famicom just the Fami so not sure if the same applies.  The plug I have comes with several different adaptors for the tip and each side has different markings so one is  - o) + and the other is - (o+ there doesn't appear to be any other switches or places to set polarity. I think that's done by the way you insert the tip attachment.

I'm being cautious because the system has cost me over $100 which I can't afford to lose on the off chance I've made a mistake.

Hello there, sorry for another "will this work" question, but i want to be sure :)




Okay, it seems to be center positive. Is there any was change it with conector or something?

Sorry, but no....

And it won't work on Twin Famicom, either, because of 9V DC output. The Twin Famicom needs a 7.5 or 7.6 DC output. And the Twin Famicom's amp needs to be at least 1.25A.

You can change the polarity,it's very easy.

I've made a quite a few ac adapters that way.

I got a Super Famicom for Christmas, and I beleive the Super Famicom and Famicom use the same power so I figure this fits this forum.

I got a power adapter that I use for my NES and SNES and it has this stuff on the label:

AC/DC Adaptor
Class 2 Transformmer
Model:MKD-48091000
Input: 120VAC 60 Hz 13W
Output: 9V DC 1000mA
Listed (+)------------(o------------(-)

Bad idea to put it into the Super Famicom? I want to make ultra sure so I don't blow the thing up so that's why I'm asking.

jinshu

Famicom and super famicom can use the same, 10V DC 850mA center negative, the adapter you got will work fine also,

but nes and snes not, nes is AC input and snes DC, the snes will work but you will destroy it eventually.

Well. Guess that means the Super Famicom I got is broken then. Black screens on most of the games I've tested and the ones that run for a short while just get stuck on a black screen during a fade out. What a bummer.

It may not be broken, just dirty. Give everything a clean and make sure to get that cartridge slot all shined up. There's always hope!
