Cute little preamp inspired by JBoz/F5

Your choice. If you're using electrolytics, try the inexpensive
Elna Silk types.

Learning to use sims has been fun. I wish I'd done this sooner--it has taught me a great deal about these little amps I love.

Thanks for challenging me to do this, Nelson!

R9 and R10 make it into something different yet, I think.

R9 and R10 have a tremendous impact on the circuit's gain. Without them, gain drops down to unity as my circuit is drawn.

I attempted to measure the noise of this circuit's output. I turned the input pot down to zero. If I did this correctly, the circuit's dBV appears to be very quiet!
