[XCSSA] Replacing Nintendo (NES) Electrolytic Caps

[X-otic Computer Systems of San Antonio]

Given that I'm doing quite a bit of soldering and fun stuff with my  
MidiBox projects, I figured I might as well do a bit of maintenance on  
my NES. It works like a champ (original 72-pin connector even) except  
that there are wavy lines and distortions on the video out. I think I  
may have mentioned this before.

Well, yesterday I opened up the NES and, sure enough, there's a 2200uF/ 
25V electrolytic cap clearly visible on the RF board, and a few other  
tiny electrolytics on the main-board. I'm planning on replacing the  
whole lot. Question I have is, has anyone done this type of work on  
the NES and has some things I should be aware of?

One of the stumbling blocks is that the RF section is shielded with  
the shield sandwhiched between the mainboard and RF board. The two  
boards are SOLDERED together at multiple points. Uhh, is that really  
necessary? :P While I can likely replace the 2200uF cap (it pokes out  
through the shielding which is how I know it's there), I'm curious if  
there are any other caps I might need to replace in the RF section.  
But I can't get to the top-side of this board without desoldering a  
buncha stuff, and I didn't want to do that unless I had to. I think  
I'm going to go ahead and buy a new 72-pin connector, too, but that's  
fairly trivial by comparison.

On the note of the caps, though, you can really see the progression of  
technology :) Modern 2200uF/25V caps are 2/3rd's the size of the one  
in the NES.

Either way, I'll let people know my results once I have replaced the  
caps (need to put an order into Allied since I've run out of extra  
caps at this point :) to see if it helps!
