CONSTRUCTION OF 25W AUDIO AMPLIFIER USING LM1875

ABSTRACT
The title of this project is to examine the design and construction of 25w Audio Amplifier. At
end of this work student involved in this project shall be able to understand the operation of an
audio amplifier, to read and analyze the circuit diagram of an amplifier, understand the wiring
and configuration of transistors and to understand the impact of heat sink on transistors The
research discovered that this fays people normally have to address large gatherings data time and
an efficient means of communication has to be used, if not, the message cannot be heard by
people at long range. The researcher recommended that use of amplifier should be made
effective so that people can address large gathering at a time so that were ever you are you will
be communicated.
