PURPOSE:To enhance the picture quality greatly by obtaining the focusing voltage at an optional point of the resistance through the parallel connection between the serial circuit part of the diode and at least one coil step of the divided secondary side high voltage coil as well as the parallel connection between the capacitor and the resistance. CONSTITUTION:The parallel circuit of capacitor 5 and resistance 6 is connected between the cathode of diode 4-1 and the cathode of final-step diode 4-2, and thus the focusing voltage is obtained at an optional point of resistance 6. As a result, the picture quality can be enhanced greatly to be applied to the TV picture receiver or the like. |
