Simple Audio Amplifier Circuit. Simple audio amplifier step 1. You can also make the circuit in the breadboard.
Since the lm386 is a mono amp i used 2 for stereo. Picture above shows schematic for this project. But there may be loose connection so i have directly soldered all components.

Components required transistor bc 547 npn 2 resistor 2kω 2 resistor 10kω 2 2kω each one electrolytic capacitor 47µf 16v electrolytic capacitor 1µf 16v 2 loud speaker 9v battery. Since the lm386 is a mono amp i used 2 for stereo. Here are some pictures for making the circuit. For testing you can use mp3 player computer mobile phone or any other device with audio.
