Scheme of power amplifier
150 Watts above is a series power amplifier is quite simple with the use of
electronic components that are not too much. This arrangement requires only 5
pieces of the transistor as a major component. No option circuit amplifier equalizer
on it because it could be said this series is quite so simple, so don't you
compare it to the sale of the market which is usually equipped with a sound
system and equalizer settings.
But to add to your collection series, this
series is pretty easy and cheap to do and maybe someday you could ever need as
a weak signal of the amplifier electronics. Or you can also make this amplifier
as a high-frequency signal from the output of the animal repellent and I
guarantee the result is very satisfactory.
The required Power supply is
a power supply two polarities: +-45 volts. The maximum power that can be
obtained by a series of amplifiers was around 150 watts. As the volume manager
you could add variable resistor 10 Kohm in series to the input. Use the Loudspeaker
with power 150 watts. Use a heatsink on a transistor-transistor amplifier or loudspeaker drivers late as Q1 and Q2.
