Ok. Sweet. I'm using an two old lipstick containers strapped on the back of my nano for true rocket style status. I originally had one, but it wont lay flat, and plus I can use one for a perfect im716carrying case. The other will have the caps and a round headphone jack I found on smallbearelec.com part 0627. Pics to come.

I would remove all four caps 86, 87 and 53, 54 and then use 53, 54 caps pads.
If after modification you still can regulate volume with the click wheel it will degrade the SQ.

Ok. Bought the 1st nano, caps and all parts! The weather is sucks, so it could take few days longer to deliver all stuff!

What I'm most worried about is taking the ribbon out. So far, I've just been trying to do it still connected through the very small pry spot. VVS if I do take out 53,54 pads, I will def. need to disconnect ribbon. Do you know how to do this? I can't really get a good feel for the mechanism by looking at it from this view.

I don't have mine yet. Go to Youtube. There you will find lots of video how to disassemble your nano.

dcc84, look at my pictures. You'll notice the black bar going across the ribbon cable slot, that flips up(both of mine are open in the pics). Just use a jewelers flathead screwdriver to flip it up. Its easy!

Thanks for the heads up vvs and wgr!

Got it! Wasn't even that bad. Just had to know where to look. Ok and I'm sure this is mentioned in the thread but I've already been over it so many times and can't remember, if I take out 53,54,86,87 caps and reconnect to 53,54 pads, does this still preserve the regular headphone jack or not?

I though that you need to take apart some peaces to get access to the cable. And you just needed to unlock the connector! LOL!

If you take out all four caps, you disconnect both the lineout and headphone jack. The advantage of the nano 1G is that the solder pads are huge compared to the 4G, so you don't need to disconnect anything. Unless you're using huge gauge wire, you don't need to remove any of the caps. Even the 4G solder pads were big enough that I didn't have to remove anything. I truly don't understand this insistence on removing the four caps.

This isn't necessarily true, but either way you don't want to be regulating the volume of your line out with the click wheel; that should be the amp's job. In any case, leave the caps in so that the line out and headphone jack will still work.

Does anyone know what value the output coupling caps are in an unmodified 4G iPod to the headphone jack?
