Audio Amplifier

Download collection of circuits Tube Audio power Amplifier. This is a PDF in English published in 1947 and features 45 complete schemes of tube amps,

This is C5198 and A1941 transistor amplifier circuit diagram. this amplifier can make a maximum of 50 watts.

The 170W Bridge Amplifier TDA7294 IC with Bluetooth is a powerful and versatile audio amplifier that can be used in a variety of applications.

This is Bass treble circuit diagram. every amplifier need this circuit as a pre amplifier. this is mono circuit.

This is a bass treble controller circuit. this circuit needs to control the sound quality. every amplifier needs this circuit to control the bass and to control the treble. There is no pre-amplifier in this circuit. if we use a pre-amplifier then it will be good. it’s a mono circuit. if we need stereo then we have to use 2 circuits to make stereo. if we don’t use this circuit for our amplifier then we will get raw sound. that sound will be not good to hear.

In this project, we have designed a 120W power amplifier using the TDA7294 IC with a potentiometer and MP3 Bluetooth.

The 140W audio amplifier circuit diagram discussed, showcases the utilization of high-powered transistors to achieve excellent audio results.
