I'd be happy to list on whatever they can dish out. While I don't understand electronics theory and operation very well (might take some courses on it someday) I'm sure I could learn a thing or two: like the following...
There's obviously an input side and an output side to a resistor. In the Apple drawings, this is shown as 1 and a 2 on it. Now how to find out the right side, as we don't want people running wires around the resistor, but into the resistor.
Oh okay, I found out the answer: 181 printed on the SMD resistor means its 18x10^1, which is 180 Ohms (which is what the drawing said) and so set the DMM to 200. Hold one probe on the capacitor (-) side, and probe the left side of the resistor. About a couple of Ohms. Measure the other side: Ahh 178-ish Ohms. So that means folks should solder a wire onto the LEFT side of the resistor, which is the input side.
Right? If so, how would I "say that" in electrospeak? Also, what would be a good ground hookup in case wires have to be run someplace? I also was told that the whole +5V supply filters are just power decouplers, right?
Edit: multiple edits, in fact...but: You're sure C3 is the Left DC output blocking capacitor, and C4 is the Right? If you look at the BOMARC schematics (Floppy, SWIM, audio) you'll see it says UB10 is the Right audio and UB11 is the Left audio. C3 is married to UB10, and C4 is associated with UB11. Pardon me if I'm all over the place in this post, I was monitoring the local Sheriff when someone decided to beat it on a bicycle in an RV park (and apparently got away).
