Should I eat – er, solder – this? I'm building a preamp and I just discovered that I'm low on 0.1μF 50v ceramic disc capacitors. My question is about whether it's worth trying to salvage more from another (already disassembled) piece of equipment. [more inside]

I'm an old stodgy audiophile finding myself forced to resort to iPod, but I want to make the most of it. First of all, I'm looking for a solution that will allow me to use line-out audio on my ipod (5th generation), and simultaneously charge via AC. Does such a thing exist? Also, what's the standard audiophile solution for on-the-go listening? Headphones into mini-preamp into dock, I'd suppose?
