Circuit Diagram

 LM386 amplifier circuit diagram Here is a diagram of a system of LM386 / LM386 amplifier that can be used as a simple audio amplifier to increase the sound of your radio, MP3 players, etc. The circuit is used LM386 amplifier IC, the maximum gain of the circuit can be adjusted from 20 to 200 circuit diagram, 10 uF capacitor pin 1.  Circuit diagram, 8 is used to adjust the gain of 200. If you want to earn 20 capacitor 10uF remove the pin 1-8. This work LM386 Circuit 9 volt or 12 volt from any source such as an adapter or battery.

This is a guitar amplifier very simple circuit diagram, easily portable and can be used for practice or guitar loop monitoring. This guitar amplifier circuit is built around an IC TDA7052 is an excellent IC uses only a few external components and provides an output of 1.5 watts with a 9 volt battery. The entire circuit can be .Circuit diagram , easily installed in a small box with the speaker. Use 8 ohm speaker to the circuit, you can also try an 8 ohm speaker that junk. I tried an old radio cassette 5 inch speakers I scrap and it worked tremendously.
