Design and Construction of 45w Audio Power Amplifier

Design and Construction of 45w Audio Power Amplifier

ABSTRACT

This thesis gives the account for the design and construction of a 45W Audio Power Amplifier with the objective of producing a reliable and cheaper amplifier that can be used in a household or stage.

The Audio Power Amplifier was constructed with electrical/electronics components such as resistors, capacitors, transformer, transistors and so on. Many tools/instruments like soldering iron, multimeter and so on were used.

The 45W Audio Power Amplifier when compared with other types of Audio Power Amplifier of the same rating in the market is cheaper as the components and materials used were locally sourced and selected to suit the desired purpose and environment.
