 Help I think I messed up.

I tried getting a clearer picture by seperating or closing the gap between the coil on my rev. 07 famicom. But all I get now is eather snow or black & white alternating lines in different variations. I'll add pics later(currently I'm making this on an iPhone.)

So have you tried tweaking the coil with a non metal object?

I initially didn't. I used one of the tools from a set that can be bought from RadioShack that has two tools with brushes to clean a soldering iron.  Undecided

How much "tweaking" have you been doing? Can you put it to the original position?
It's a lottery to try to repair it like that...
 ... ehh don't worry, make AV mod and forget about RF.
There has been a discussion not that long ago:

Last time I did the av mod it didn't work. Due mostly to the schematics being wrong. I was even gonna use the avfc/sfc av connector. Also I think the one I was following was from a Japanese site.  Cry

Also can stereo be gotten from the SOU solder pad? And why no method on FW for using the other pads?

Well that's because you haven't followed this:

There are ways to get some kind of pseudo-stereo by separating the individual sound channels, but I don't think it's worth it.
What do you mean by using other pads?

I mean besides the SOU solder pad there's the GND, VIDEO, CLK, and VCC solder pads on the original revision boards till rev. 07.

Those are only for the test purposes, for a jailbar-free and "proper" AV mod, you have to find better spots to solder on.
And, correct me if I'm wrong, but I think the SOU soulder pad is positioned before the external audio from cartridge mixing in, so you won't get the extra sounds from this solder pad.

This pad also connected to the extension jack, so all in there Smiley

Well, what about the connector that connects to the Power/RF board? You know the ones with VCC, A, V, and G .

Is it possible to mess with the rf coil to make the fami work on american tvs? I have an extra fami and a tv that doesnt have av input and only goes up to 87 or something like that. (19sv111)

I don't think so - channels quite far away from each others and you have to shift carrier something like 20MHz down. Also there is at least 3 different revisions of RF unit exist, so i can not help much at moment.
