I got the first stethoscope design to work. It works well. However, I tried building stethoscope #2 from scratch exactly as described and I get no sound at all. I had to build this circuit for a lab project. Due to time constraints, I'll be presenting the first design. Design #2 sounds awesome but can't get it to work. Thanks for all of your discussions. They helped me go in the right direction. mannyt01
