The output power for this LM380 power audio amplifier circuit is around 2 watts in single way on a 8 ohms load impedance .
If we need more power than 2 watts we can connect two circuits in bridge mode like in figure below .
For this audio power amplifier circuit we need to use a 18 volts dc power supply .
