LM386 to get 74dB (Pixie 2 audio amp.)

JF1OZL describes the LM386's circuit with a higher gain. The LM386 gets 40dB as an original circuit provided by the data sheet (10uF pin1-8 connection). This article describes 74dB gain with the circuit.

If you didn't get enough audio gain on pixie 2, you may change to the circuit to get the higher gain.
