60 Watts mono Amp

This is a circuit diagram of 60 Watts output class B power amplifier. The supply voltage is 48 Volts. We recommend not increasing the voltage if you want to run the amp long time. You can build this amplifier for low cost. The output transistors are 2N 3055 which are not expensive.

Circuit diagram shown a one amplifier means mono amp, if you want stereo amplifier which is 60W + 60W then you have to build two sets of this. Remember this is not for a beginner, you need to have some experience with electronic circuit diagrams and components before you start this project.
