Abstract of the Disclosure A resonant magnetic deflection circuit is dis- closed for reducing a retrace period of an electron beam scanning within a cathode ray tube (CRT) appara- tus. Opposite polarity flyback voltage pulses occur at both ends of a deflection coil. As a result, an effec- tive retrace voltage appearing across the deflection coil is approximately doubled, thereby reducing the retrace period of the electron beam scanning within the CRT apparatus. One end of the deflection coil is connected to a reference level source through a first parallel circuit and an S-correction capacitor, the other end thereof being connected to the reference level source through a second parallel circuit. The first and second parallel circuits comprise switching devices, damper diodes and retrace capacitors. More- over, both ends of the deflection coil are connected to a power supply through a flyback transformer.
