Class B Audio Amplifier Circuit Diagram. The 15 w class b audio amplifier circuit shown here is a simple class b audio amplifier based on lm833 op amp tip41 and tip42 transistors. We know that a transistor requires 0 7v at its base emitter junction to turn it on.
The circuit diagram for a push pull amplifier consists of two transistors q1 and q2 which are npn and pnp respectively. This particular circuit is called a class b push pull circuit. In our analysis of the circuit we will consider the class b amplifier.
Most audio power amplifiers use a class b configuration where one transistor provides power to the load during one half of the waveform cycle it pushes and a second transistor provides power to the load for the other half of the cycle it pulls.
