I was just thinkin' about putting together a bill of materials to build at least the amplifier circuit. Looks like we're getting closer to a finished design, so maybe I'll be able to purchase everythnig I need all at at once. I'm pretty pinched for time right now, bu I think I can assemble this preamp fairly quickly and I think it'll be fun.

Thanks for your input on this project, and to everyone else participating too!
