6-10 VERTICAL OUTPUT CIRCUIT SECTION
IC501 amplifies sawtooth waveform output from TDA9102 Pin 15 and supplies it to
deflection yoke. IC501 uses Pin 5 to output the amplified wave. IC501 Pin1, receiving
sawtooth waveform output from TDA9102 Pin15, amplifies and output it through amplifier
embedded in chip and supplies it to reflection yoke. The outputting terminal is composed of
C505, C511 and R508 R507.
Pin 2 is a terminal supplying reference voltage.
Pin 3 is pulse generator and Pin4 is used as GND.
Pin6, as B+ terminal of TDA 8172 device, supplies 24V voltage and drives circuit. It supplies
current necessary for vertical deflection through C503 and D501.
R508 and C511 is a circuit used for DAMPING to prevent current flowing in DY coil from
distorting during switching.
