The self-made independent element 50W hi-fi power amplifier circuit

The power amplifier stage of the amplifier circuit consists of the compensatory tube emitter follower, the backward feedback of the big circuit makes the drive compensatory tube signal in the linear range. The circuit makes sure the 2 tubes conduct in different time in the structure, so the power supply won't be short. Ideal transistors can conduct or block quickly, however, triodes switch speed is limited, not to say the large power tube. When the changing signal which is put in the tube is reversed, the 2 tubes may be conducting at the same time.
