I need help with LM386 headphone amplifier?
I build a headphone amplifier based on this instructable https://www.instructables.com/id/LM386-Audio-Amplifier/step3/Observe-Diagram/ (will post schematic below). I'm using a 12v 800ma power supply (it read 18v so I'm using a +12v regulator. At first the sound was loud but very distorted when the potentiometer was turned all the way up. I added a 10 ohm resistor to the middle lead going to pin 3 on the lm386. I also did some other stuff but I do not remember what. Whatever I did made the sound very clear, but now the sound is quiet even with the pot turned all the way up. It would be louder to just plug it into my sansa fuze! Any help at all would be very much appreciated, I don't know much about audio stuff so I'm puzzled here.
