I built a little audio amplifier last week using the LM386 chip.
It works OK as long as I keep the voltage above 6V, but it gets kinda distorted if I try to use voltage below 6V (even though the specs say it will work with 4V). I don't know, maybe the battery is not supplying enough amps at 4V.
Anyway, I have this old portable Sony radio from about 10+ years ago:
**broken link removed**
This thing runs off two AA batteries, and sounds great!
Any idea what kinda of circuit it uses to amplify the speaker?
I'd rather not take this thing apart as it still works, and if it ain't broken, well...
Thanks,
Drew
