Chony,

I don't have the schematic for the 9000. This board is for the 3000, but the connections at the plug are very similar. However, you can determine which connections to jump if you have an OHM Meter. Without the board, the signal cannot get to the speakers or the headphone.

Sorry I cannot be of more help,

Gary
