2n3055 Transistor Amplifier Circuit Diagram. In the circuit uses all transistors like 2n3055 and small transistors. Easy amplifier circuit diagram using 2n3055 only.

This audio amplifier is built about most famous 2n3055 transistors. 2n3055 is a single diffused npn silicon transistor in to 3 case. Though it is a too old circuit.

Take a note that you must use aluminium heatsink and a fan to prevent over heating on the transistor 2n3055 mj2955.

I often recommend this project. I get the circuit diagram from a book of debashis bandhopadhyay erc publication. It is the circuit that gives bland excellent sound because of using the transistor entirely hot part 2n3055 x 2 have no ic mix. 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.
