Jeh, got it now. You can pull the bias voltage right off the CP9. The two 10k resistors (to the right of the 9k1 on the schem) form the voltage divider. Tie that to your 10k that connects to the non-inverted input of your TS stage. Or, just add two extra 10k resistors on your daughter PCB tied to the 9v supply and create it's own bias supply. If you do this, use a 10uF cap from the second 10k to ground to give it a little filtering.
