... value in the LC resonant interval, it amplify video signal to drive horizontal output transistor Q801. Horizontal Driver Circuit The driver pulse that come from U401 pin7 drive Q506,then transfomer T501 convert driver pulse to driver current to about 1103Vpp in different horizontal frequency. Horizontal Output Stage There is U301(KA2143B). Hf Cs...
