Apparatus for automatically limiting excess beam current conduction of a kinescope in a television signal processing and reproducing system. A control network including an active device (e.g., a transistor) provides a control signal representative of the magnitude of beam current conduction when above a predetermined threshold level. A dynamic operating control range of the active device is determined independent of a threshold control level of the active device by means of a degenerative direct current feedback network associated with the active device. The control signal is coupled to the kinescope for opposing excess current conduction thereof. |
