More than eleven years after its publication on this website and an ever increasing success, the 3 - 5W Class-A Audio Amplifier has undergone some small modifications (the addition of R1, Q2, R6 and the substitution of Q4 with a Darlington transistor) capable of producing a major improvement.

This is a mono 100-watt transistor amplifier circuit diagram. this circuit diagram can make 100 watts using one pair of transistors

The modified C-Class Sixteen model of the Harman card company in 1976 is able to deliver 400 watts of power through a 4-ohm speaker with an AB class Amplifier c

Constructing a 150W Amplifier Circuit Diagram using TIP3055 can be a rewarding DIY project for audio enthusiasts and professionals alike.

Audio Amplifiers are being used for decades. The main function of an audio amplifier is to reproduce the input audio signal at sound producing systems like speakers with desired volume and power levels. The frequency range of audio signals is between 20Hz and 20,000Hz. Hence, the audio amplifier must have good frequency response over the […]

A compact audio powerhouse ideal for guitar or PA work or for use as a general-purpose subwoofer or hifi amplifier. Many people prefer Mosfets because of their legendary ruggedness. Altronics had a Mosfet amplifier module which produced 200W into a 4 Ohm load and so we decided to take a look it. It turned out to be based on the
