The circuit is shown as the figure. Usually, the drive tube needs to use transistor (Figure 9013) with higher withstand. When the output voltage increases, VT55's bias increased, then the forward current of light emitting diode in B5 increases, so that the voltage across poles of photodiodes decreases, the adjustment tube BE junction bias voltage is lowered while the internal resistance increases, so that the output voltage is reduce ; Conversely, the output voltage increases, thereby maintaining the stability of the output voltage.
