Apparently, I had a boatload of AC/DC adapters in a milk crate inside the medium-sized cardboard box on the utility shelf in the garage where I keep my power drill and soldering iron. Two of them would have worked with the Panasonic CD player. Plus, I had 2 other universal AC/DC adapters exactly like the one I bought at Fry's yesterday. (Neither of these other ones would have worked with the CD player, however.) Maybe in the future, I won't buy more stuff that we already have.
