Diagram 3055 Transistor Audio Amplifier Circuit 12v. This a 24 watt class a amplifier circuit made from discrete semiconductors like 2n3055. Although the amplifier above looks too simple to make the low tech design forces the 2n3055 to dissipate a lot power through heat.
As the circuit diagram below the input terminal wants an unregulated dc supply 15v to 20v. To begin with an electrical current flows through the resistor r1 to limits current to the zener diode. Simply by incorporating just four transistors in the quasi complementary configuration this 2n3055 simple power amplifier circuit can deliver a good 100 watts of power over an attached 4 ohms loud speaker and the entire design can be built at a really low cost to be precise it would cost you only 1 2 per transistor.

In this video we are going to show you making a powerful amplifier circuit using only two transistor. To begin with an electrical current flows through the resistor r1 to limits current to the zener diode. We can use 12 voltage to 24 voltage to this simple amplifier. It is a super loud amplifier circuit.
