ABSTRACT:
An amplifier stage with variable gain dependent on the anode voltage is interposed between a ramp generator having constant amplitude ramp output voltage and the vertical deflection stage in such a manner as to vary the input voltage of said vertical deflection stage in accordance with anode voltage variations. In such a manner the vertical deflection current varies correspondingly.
