Regulator Power Circuit Which Using Transistor As Amplifier

The picture shows the simple and practical regulator power with output voltage of -10V and output current of 50mA. The C2 is coupling capacitor. It makes the output port's ripple directly couple to the amplifier tube VT2's base electrode and it would not be through the sampling resistor. So the output voltage's ripple is very small. The C3 is selected between 0.1uF to 1uF.
