The post 140W Power Amplifier first appeared on Electronic Schematic Diagram.]]> The following is a circuit of a power amplifier 140W. This Circuit using 741 IC-based circuit opAmp as strengthening early before the final strengthening by four transistors thereafter. Make sure you use a heatsink on the transistors to reduce excess heat in the transistors.

140W Power Amplifier circuit diagram

Power supply used is the type of dual polarity power supply with (+), (-) and (0). For maximum performance, use a stabilized power supply with 40V output voltage and output current of 5A. Do not forget to use the good speakers to get good audio output as well .. 🙂

Good luck …
