Abstract
Circuit for automatic brightness correction in television receivers, characterized in that it comprises a resistor connected between the positive polarization source and the anode of the video amplifier valve, from whose anode two derivations are directly taken, one of the which supplies the video line to the cathode of the cathode ray tube and the other supplies the direct voltage for the brightness circuit, attacking the grid of the tube itself, while an intermediate point of said load resistance takes a potential continuous reference that is applied to the cathode of the referred cathode ray tube.
