100W Subwoofer Amplifier Circuit
This is the circuit diagram of a fully transistorized subwoofer amplifier that can produce full output 100W.There seven including four in the output stage. Transistors Q1 and Q2 form the pre-amplifier. The transistors Q4 to Q7 as the output stage. Since no integrated circuits used in the circuit is very robust and can be easily mounted on a general purpose PCB. Notes. The circuit can be powered
