14. 6 HORIZONTAL OUTPUT The horizontal oscillation signal is outputted from pin 37 of IC101 and used to switch the drive transistor 0431 This switching signal is current amplified by the drive transformer T431 and drives the output transistor Q432 When Q432 turns ON an increasing current flows directly to the DY through C441 C442 gt L441 R441 gt DY gt Q432 gt 0432 and the deflection occurs during the last half of the scanning period When Q432 turns OFF the magnetic field stored in the DY up to that point causes a resonant current to flow into the capacitors C420 and C423 and charges them The current stored in C420 and C423 then flows back to the DY causing an opposite magnetic field to be stored in the DY This field then collapses increasing a current which switches the dumper diode in Q432 ON The resonance state is completed and an increasing current then flows again directly to the DY through the dumper diode By this means the deflection in the first half of the scanning period is performed When Q432 turns ON at the end of the first half of the scanning period the deflection during the last half is begun thus completing one cycle In the PCC circuit consisting of Q461 and Q462 the parabola signal supplied from the vertical circuit is added at the horizontal output stage and pincushion compensation is performed by varying the DC bias Further the ABL voltage is fedback to the base of Q462 to compensate fo
