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. A transistor is a three terminal semiconductor device and the terminals are e emitter b base c collector the transistor can work in three different regions like active region cutoff region saturation region. It is interesting because using only one transistor.
The video amplifier in the diagram is a well known design.

The input signal enters through c2 to the base of q1. Q3 bd139 or bd137 serves as the output circuit of the common emitter follower. Transistors work as an amplifier while they work in the.
