The “Super Amplifier King†module circuit is actually a quasi-B synchronous dynamic bias power amplifier circuit. It not only has the higher power of Class B power amplifier, but also has the excellent sound quality of Class A power amplifier. It completely eliminates the switching distortion of Class A and B amplifiers. The actual circuit is different from the super class A dynamic bias circuit introduced abroad. It has a concise structure, integrating overvoltage, overheating, overcurrent, anti-speaker impact, anti-level reverse connection and other protection functions in one. In terms of static micro power consumption, dynamic response speed; low distortion and power frequency response, as well as the sound effect of "tube amplifier" have reached a considerable level.
The circuit of this module can amplify the rich even harmonics contained in the audio signal, make the harmonics and aftertones in the music details flexible, have a long rhythm, and have a natural reverberation effect, and the bass reverberation is also not dragged. The "thru express" with only three levels of amplification pushes the transient response to the magnitude of the power supply voltage, and the bursting ability is quite good. In order to let more audiophiles understand the performance characteristics of this circuit, the circuit is now analyzed as follows.

Reverse Conducting Thyristor(RCT)
Reverse Conducting Thyristor(RCT) is also called Reverse- appreciation Thyristor.The characteristic is that a diode is connected in reverse parallel between the anode and cathode of thyristor, so that the transmitting junction of anode and cathode is short-circuited.As a result of this special circuit structure, it has high voltage resistance, high temperature resistance, short turn-off time, low switching voltage and other good performance.For example, the turn-off time of the reverse thyristor is only a few microseconds, and the working frequency is dozens of KHZ, which is better than the fast thyristor (FSCR).This device is suitable for switching power supply and UPS uninterrupted power supply. One RCT can replace one thyristor and one continuous current diode respectively.
