G-3. Vertical Output
IC U601(TDA 4866) is the vertical amp IC, the output pin6 connect to the YOKE .The sawtooth
current float across the YOKE to make vertical deflection. Fig.3 is the block diagram of IC TDA4866
G-4. Horizontal Driver Circuit
The driver pulse that come from U401 pin7 drive Q417,Q416,TO Q503,then transfomer T501
convert driver pulse to driver current to drive horizontal output transistor Q504.
