As for the auto power off mod, that went wrong too! I fluffed the solder a bit to the top right contact point, and it seemed to disappear leaving no metal to contact. Doh! After a bit of experimentation, I found that the same lower right leg of the other component (marked 2 in pic below) when jumpered to the resistor right next to it (marked 1 in pic) put the Tunecast into an always on state.
