A resonant retrace vertical deflection circuit comprises a retrace capacitor which forms a resonant circuit with the yoke vertical deflection windings during retrace of the electron beams. One or more diodes isolate the yoke from the circuit power supply to allow the yoke voltage to increase beyond the level of the supply to provide faster retrace. A second power supply is provided to precharge the retrace capacitor prior to retrace, resulting in a further decrease in retrace time.
