This particular circuit is called a “class B,” push-pull circuit. 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 ).

The Class B audio amplifier circuit can generate output 15 Watt at 8 ohm speaker. While the power supply voltage is needed is a symmetrical voltage +/- 12VDC. Each operational amplifier contained in IC LM833 has a different function. IC1a serves as a buffer (buffer), while the ICB serves as an inverter mode and negative feedback.
Audio Amplifier Circuit 15 Watts Class B

The circuit shown here is of a simple Class-B audio amplifier based on opamp TL082, transistors TIP41 and TIP42. LM833 is a dual opamp with high slew rate and low distortion particularly designed for audio applications. This audio amplifier circuit can deliver 15 watt audio output into an 8 ohm speaker at +12/-12V DC dual supply.

The Class B amplifier is as basic as they come, yet still has a nice and warm sound to it. It is consists of two separate stages, the first one is responsible for the voltage gain of amp and to set a correct voltage offset for output. The second part of the circuit uses power transistors to boost the current the amplifier can supply the load with.

The circuit of a push-pull class B power amplifier consists of two identical transistors T 1 and T 2 whose bases are connected to the secondary of the center-tapped input transformer T r1. The emitters are shorted and the collectors are given the V CC supply through the primary of the output transformer T r2. The circuit arrangement of class B push-pull amplifier, is same as that …

Class B Amplifier . The Class B amplifier is a bit different from the Class A. It is created using two active devices which conduct half of the actual cycle, ie 180 degrees of the cycle. Two devices provide combined current drive for the load. In the above image, an Ideal Class B amplifier configuration has been shown.

Amplifier analysis shows that a Class B amplifier has a no-feedback distortion of about 33% and a Class A amplifier has a no-feedback distortion of about 8% and sound better than Class B. Most of the Class B distortion comes from the use of the output transistors as rectifiers to separate the plus and minus halves of the signal as well as then amplifying those halves separately …

A basic class-B amplifier consists of a pair of transistors, driven in anti-phase but driving a common output load, as shown in Figure 3(a). In this particular design, Q1 and Q2 are wired in the common-emitter mode and drive the loudspeaker via push-pull transformer T2, and the anti-phase input drive is obtained via phase-splitting transformer T1.
