Npn Transistor Guitar Amplifier Circuit Diagram. Guitar amplifier 10w old style ultra compact combo two inputs overdrive treble enhancement the aim of this design was to reproduce a combo amplifier of the type very common in the sixties and the seventies of the past century. Not only that see a higher power amplifier than this below.

In this article we will study how a transistor can function as an amplifier. In most of the electronic circuits we use commonly npn transistor configuration which is known as npn transistor amplifier circuit. The circuit diagram for the common emitter amplifier configuration is shown below.

Let us consider a voltage divider biasing circuit which is commonly known as a single stage transistor amplifier circuit.

It is suitable to learn how the transistor works. Let us consider a voltage divider biasing circuit which is commonly known as a single stage transistor amplifier circuit.
