An LM386 Audio Amp, with Audio AGC Circuit?
« on: December 05, 2025, 1928 UTC »
https://ganymedeham.blogspot.com/2013/08/lm386-amp-with-agc.html    That schematic is kind of vague, but that feedback loop, with 10uF CAP in it is from pins 1 and 8. Output is pin 5. And, pin 2 is Audio IN. Pins 3 and 4 are tied to Ground. And VCC is +12VDC on pin 6. Pin 7 is N/C. Still, I like the simplicity of this. (Boomer, helped fill-in the pins on this one.)

meows in Los Angeles. Do you understand this? Now, radio is
exactly the same, except that there is no cat.”

That's a crap circuit.  It'll just clip and distort.  If you want a proper audio AGC, it's a bit more complicated than that awful circuit.

Indeed. Simple rarely means Good.

The LM386 is crap anyway. There's much better devices.

Please dont ever show a receiver with sn NE612 in the front end.

'It's better to give than receive' so why Rx when you can Tx!
