AUDIO AMPLIFIER CIRCUITS Archive

100W, 300W, and 500W transistor power amplifiers have been prepared with a similar logic. There are some differences in the circuit schematics, but they are designs that address different levels..

This stereo amplifier circuit built with STK4131-II is a practical audio amplifier solution that can be used at home, in a workshop, or in small workplaces. The circuit has an..

Although a stereo structure is often sufficient in home audio systems, a four-channel, that is, quadraphonic amplifier can provide a wider listening area and surround sound effect. In this project,..

The JHL 1969 Class A headphone amplifier is a fully transistorized stereo headphone driver that operates with a ±12V symmetrical supply and draws continuous current. It is suitable for those..

Years ago, I had built a TDA7265 amplifier circuit, but I did not know it was this good at that time. Back then, high power was more interesting, and I..

A TDA7294-based subwoofer amplifier design prepared for in-car use. The TDA7294 IC is used in the output stage, and the circuit can deliver approximately 100W level power. Since a high..

@Uğur EKER details of the 2X160W transistor amplifier project he mentioned in the Hi-End Car Amplifier Circuit with TDA7294 and UPC494 article. The PCB design has been carefully prepared. The..

The LM4780 power amplifier IC used in Genelec 8030A active studio monitors has now become one of the components that is difficult to find on the market. Especially in recent..

LM3886 has long been a popular power amplifier IC in hobby and semi-professional audio projects. The main reason for this is that it can provide high sound quality with relatively..

The RIAA gramophone preamplifier circuit is a stereo preamp circuit designed to raise the low-level signal of turntables with magnetic cartridges to a level suitable for AUX, line-in, mixer, or..
