150W OCL POWER AMPLIFIER CIRCUIT DIAGRAM
The amplifier circuit is very CHEAPEST and Can be powered from 24 to 32 V/5A dual power supply. You must try this circuit. Its working great. Because Transisitor on the final amplifier will of some very hot then add the aluminum finned cooler and the fan so That the transistor is not too high temperatures.
Note:
Use 24V/5A dual power supply.
Connect a 50K POT in series with the input as volume control if you need.Not shown in circuit diagram
