Thanks for the ego-boost, Brad. I see my natural self-deprecation is wasted here. "Og recognize color-coded cable and input jack, grunt."
Og recognize color? Og have big brain!
I'd still hit some of the big-box sites. If you're close to a Wally World, Best Buy, Target, Sears, etc, check their clearance rack.
Radio Shack would probably have it.
Don't count on it. I was in a local store yesterday (the one I managed some 20 years ago) and it was pathetic. Just guestimating, but I'd say they probably carry a third or less of the component and connector inventory they used to.
