Stereo Headphone Amplifier Circuit Diagram. For example r101 q101 c101 etc. C3 is the power supply filter capacitor.

This headphone amplifier circuit is made by using lm386 audio amplifier ic. This circuit is made in such a way that user can not only use it as headphone amplifier but also can drive a subwoofer speaker or normal speaker 4 ohms and can get a amazingly loud sound through the speaker. Here s a top class headphone amplifier that can drive high or low impedance phones to full power levels with very low noise and distortion.

For example r101 q101 c101 etc. For best performance it can be teamed with the stereo preamplifier described last month. For the parts lists on the right channel will start with the number 10. R1 and r2 are the respective input resistors.
