Fig.1
Fig. 1 the Q808, Q809 and T801 form a Push-Pull configuration.
When Q808 turn on, then Q809 turn off
Q808 turn off, then Q809 turn on.
The result in T801 primary coil has an AC square waveform.
Certainly, the secondary of T801 will produce high voltage AC square waveform.
Through C817 filter capacitor, will output sin waveform. T802, C824 are also the same.
