<p>A resonance pulse voltage of positive polarity is impressed on a horizontal deflection coil included in a first resonance circuit by the first resonance circuit and a third resonance circuit. A resonance pulse voltage of negative polarity opposite to the resonance pulse voltage of the first and third resonance circuits is impressed on not a transistor, but only the horizontal deflection coil of the first resonance circuit by the second resonance circuit.</p> |
