( Transistor control circuit part), other parts are the same as Figure 11-5. The two
transistors in this circuit achieve feedback through the emitter resistor . At the same time, the collector of VTi and the base of VT2 are directly coupled, thus achieving
higher sensitivity and better stability. This circuit is a human-filled automatic control circuit .
