Hello.
Will have to build a pre-amplifier for a low impedance ~36 Ω dynamic microphone on voice-only range less than 4KHz, with a single transistor, and powered by ~3V from a single 18650. It will feed a PAM8302A chip ---> https://cdn-shop.adafruit.com/datasheets/PAM8302A.pdf
Suggestions for reliable performance ?
