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.
💡 Use mica insulators and thermal grease when mounting 2N3055s to a shared metal heatsink. Fusing: Place 2A fuses on both the +Vpositive cap V −Vnegative cap V rails to protect the transistors from shorts. 2n3055 Audio Amp Schematic
potentiometer is usually placed here to adjust (to prevent crossover distortion). Output Stage (The 2N3055s) 2n3055 Audio Amp Schematic
The collectors of the 2N3055s are connected to the positive and negative power rails. 2n3055 Audio Amp Schematic
