drop rectifier and regulator, so that the volume of the circuit is greatly reduced. CJ capacitor step-down capacitor, VD1, VD2 rectifier diodes. AC 22V voltage through cl down and VD1, VD2 rectifier, by the resistor Rl and regulator VD3 stable output 6V DC voltage. Filter capacitor C2 is further filtered except the power to bring the high-frequency component.
