Wow! Those resistor values are even more rangey than I'd imagined. I'll play around with it until I get it right. Thanks for the answer.

This blue LED is so bright at night...it's like staring into the sun! I've been getting tired of putting a credit card in front of it!

Nice preamp though...uses 6922's mounted on a circuit board. $400 DELIVERED from Thailand. Not bad.

Thanks,
Mark
