I wanted to control the gain with feedback and I used EC's tools to help me. It was a fun circuit to build in EC. It turns out that the first stage is highly beta dependant. It doesnt work as currently configured for 2n3906 bjt. If someone wants to build this 2n3906Y change the feedback bias to two resistors from 20v to ground.
