Abstract
A diode is coupled between a winding of the high voltage transformer and a source of direct current potential and is polarized in a manner which provides for non-conduction when the deflection system is operating properly. When the deflection system malfunctions in a manner to increase the amplitude of signals developed thereby, the signals forward bias the diode and provide the clamping of one polarity of the signal to the direct current potential level.
