All
the components are easily available at most of the electronic spare part
market. The components are not costly
too. When you select the mains transformer, go for a good quality one, which
determines the quality of sound from the amplifier. If you use a Torroidal type transformer, will
be better. Even though it will cost
more, it will give good results.
Select
a transformer having not less than 3Amps secondary current.
The
power transistors should be fitted on suitable heat-sink to prevent
overheating. Use of heat-sink compound
is highly recommended.
Keep
all the inter-connection wires as short as possible. Use a metal cabin to assemble this amplifier.
The
amplifier can be used with multi signal inputs.
You can note it by its input board sockets.
It
will be best to use a high-capacity main filter capacitor. 5000MFD 60V will be better.
Come
on. Go with the circuit first, and then start
your first amplifier project.
