DESIGN AND CONSTRUCTION OF 300 WATTS STEREO AMPLIFIER

Abstract

This project titled "Design and Construction of 300Watts Stereo Amplifier" is designed to produce a greatly amplified output audio signal irrespective of how small or low the audio input signal may be. It allows the use of auxiliary (CD and Cassette player) and microphone input sources at the same time. Equalization of audio output stream is also provided through the active tone control (treblelbass control unit). To accomplish the aim and objective of this project, BC147, 2N1893, BF337, BD712, 2N3055, MJ2955 transistors, 4558D, 741 Op Amp ICs and other associated components were used. In order to facilitate a better understanding of the thesis, clear and precise drawings, illustrations and references are incorporated in the thesis. This makes it to a vast extent self explanatory.
