potentiometer is usually placed here to adjust (to prevent crossover distortion). Output Stage (The 2N3055s)

as these transistors generate significant heat during operation. emitter resistors to provide thermal stability. Feedback Loop A resistor (typically ) connects the output back to the input stage. 2n3055 Audio Amp Schematic

This design typically follows a push-pull architecture. It uses two 2N3055 transistors as the final power stage to drive an 8-ohm speaker. Key Components Power Transistors: 2x 2N3055 (NPN) Driver Transistors: BD139 (NPN) and BD140 (PNP) Voltage: Dual rail supply ( ±35Vplus or minus 35 cap V Power Output: ~50 Watts into 8 Ohms Step-by-Step Connection Logic Input Stage The audio signal enters through a electrolytic coupling capacitor. potentiometer is usually placed here to adjust (to
