150 watts power amplifier circuit
Amplifier circuit is 150 watts power amplifier circuit is quite simple.
This circuit requires only 5 pieces of transistors as the main component of reinforcement. There is no equalizer option on this amplifier circuit because it can be said of this series is very simple, so do not you compare it with that sold in the market which are usually equipped with various sound system and equalizer settings.

But to add to your collection circuit, this circuit is fairly easy and inexpensive to make and maybe one day you may need as a weak signal booster from your electronic circuit. Or you can also make this amplifier as an amplifier of high frequency signal from the output circuit animal repellent and I guarantee the results are very satisfactory.
Power supply required is two-polarity power supply is + - 45 volts. Maximum power that can be obtained by this amplifier circuit is around 150 watts. As the volume control you can add potensio or variable resistor 10 Kohm in series at the input. Use dispasi loudspeaker with 150 watts power. Use a heatsink on the transistor-transistor driver loudspeaker or amplifier late as Q1 and Q2.

Simple 150 Watt Power Amplifier Circuit
This is the very simple circuit diagram of 150W power amplifier. The circuit is easy enough to built without PCB. The power output range is about 100-150W depends to the power supply and the Darlington’s you use for the amplifier. Heatsink is a must since the final transistor is going to hot when the amplifier is activated.
The amplifier requires split power supply. The transformer is depending to your home electrical installation, it can be 110V or 220V primary. Use 35V-0-35V secondary (transformer output), you will get about 45V DC output from transformer 35V AC after rectified by the diodes. The Transformer current output should be at least 4A for better audio performance. Use 4A / 100V diodes.
