I have some many power supplies, but going through them all, they are mostly 9 or 12 v. But I finally found one that is 5.7 v, 800 mA. On test turns out it's center positive, but that's easy to fix. However, I think the jack is too small. Anyhow, I can probably rig something up, if I get the board all cleaned up.
