Lm386 audio amplifier circuit with pcb it was my first mini audio amplifier. A great sounding lm386 audio amplifier. In the buffer circuit coupled with op amp ic 4558 supplied 15vdc voltage circuit power supply you can see in the picture is flavored transistor d313 and b507. Advantages of using this ic are low harmonic distortion compared to other ic amplifiers of similar.
Most of the component values in this circuit aren t critical. Many people also use it. Because it s easy to build and this ic always popular. The four transistors are wired as complementary darlington s which produces the drive for the speaker.
The circuit shown below is not at all expensive as the amplifier contains only an op amp and four transistors easily available from your electronics junk box. 2 x 60 watts stereo amplifier circuit is designed using lm4780 an audio amplifier ic that can deliver 60 watt rms output power per channel to 8 ohms speakers. Here the op amp used is ua 741 which produces the required gain. 12 watts transistor amplifier circuit description.
