What did you settle on for a resistor?

I can't remember. I used a 5v regulator to step the voltage down first. That way the resistor didn't have as much voltage drop across it. I'd have to tear it apart to see that resistor. If I did it again I might use a pass transistor and just make it adjustable.

Ok, I see. Yeah, I would much prefer to have a regulated/adjustable bias.
