9V dc, 500ma, tip positive. Note that if you measure a working one, you
will get a higher voltage because the power block is made with only a
transformer, some sort of bridge(don't know which, didn't take it apart),
and a cap. Therefore, the unloaded voltage will be higher, probably
12-15Vdc. For this reason, get a replacement rated at least 500ma, but
not to much higher. I wouldn't go above 1a. But I guess it doesn't
matter to much as it just goes into a 7805. I think you can get away with
as low as 6.5V, and much higher. The 7805 should be able to take at least
30V, but it would be limited to a much lower voltage because of heat
disapation. The most important part is just to get the tip positive.
