2 Watt Amplifier Circuit Diagram Based Cheap Transistor

This amplifier circuit is designed for small usage, usually placed on small boxes as well. Sources of input that can be used for this amplifier include a CD player, walkman, computer and other small input sources. The circuit here is a mono system. If you want a stereo system, can be made 2 pieces of amplifiers.

This circuit uses transistors that are very commonly used, the reason is to get low harmonic distortion. In addition, also look for components will not be troublesome. In order for this amplifier circuit to be applied optimally required supply voltage + 12V. Switch SW1 serves as a bass booster. When SW1 is closed, the control volume must also be fixed.

When making this circuit, the R9 resistor must be carefully adjusted and set to minimize distortion level. At the time the circuit works, it normally will suck the current about 10 to 15 mA.2 watt amplifier circuit
