PROBLEM TO BE SOLVED: To provide a power supply capable of discharging charges stored in the power supply during testing and maintenance without using large components, and a high-frequency circuit system equipped with the power supply. SOLUTION: This high-frequency circuit system comprises a power supply for individually supplying a predetermined supply voltage to an anode electrode, a cathode electrode, a collector electrode and helix in an electronic tube, an anode switch for turning on or off anode voltage output, and an anode switch control circuit for controlling the anode switch on/off operation so that the pulsed anode voltage can be applied to each of the predetermined cycles repeatedly when operations are stopped in both of a helix power supply and a collector power supply.
