Can Anyone give me a link to a AV cable for a famicom console so i can play it in the US
If you have an original 1983 Famicom, you can use a standard NES/SNES RF switch to play it in the US (tuning into Cable Channel 95). There's no such thing as an AV cable for the original FC because it doesn't have a stock AV output. You can mod it to have one though, but it involves soldering, building your own video amplifier and making holes in the console for the cables or plugs to come out.
If you have an AV Famicom, then you can use the same AV cable you use with your SNES / N64 / Gamecube system.
I have a original white and red famicom do I can use the Nes/snes
Yes. Use the regular NES RF switch and tune your TV into Ch. 95.
