FWIW, the label on my Graphite itself says "input 12V 1.25A". I believe Radio Shack has some variety of power bricks matching various input voltage and amperage needs. I have an "AC Adapter" I bought a couple years ago when I wanted to keep something cheap in a shared grad student office to listen to music on while I worked all night on a networked linux box with no CD, so I dug out an old tape player which needed 6V 300mA power input.
