Abstract
Improvements in circuit arrangements for the suppression of the focal spot in television picture tubes, of the type in which it is buried between the cathode and the wehnelt electrode of the picture tube, a voltage divider to which a service voltage is fed, and a capacitor being connected in parallel to a part of the voltage divider in such a way that when the operating voltage is stopped, the image tube is completely blocked, characterized in that the capacitor is constituted by the charge capacitor of the service voltage source, and the charge capacitor is linked with a ground potential through a diode, at the base point of the voltage divider.
