I used the schematic attached to make my video amp circuit.
I pulled Q1 (a transistor near the PPU) and FC2 (I think it's a ferrite core) from the board as well, but FC2's location differs by board revision. If you don't have these exact resistor values, string together resistors until they add to these values.
C5 is a 220 microfarad capacitor. You can not string capacitors together to increase their capacitance. Be sure you get polarity right for C5 (it's the only capacitor it matters for).
C6 is a 560pf capacitor; I used a ceramic one.

The best way to remove the jailbars that appear on a famicom is to lift pin 21. this is a HARD thing to do properly and CAN BREAK THE PIN if done wrong.
I used an x-acto knife after making sure the solder was completely gone from underneath and the pin was loose. I rotated the knife so that the pin raised through the hole. I soldered to the pin leaving it suspended above the board.
