eH blanking delay
The horizontal blanking pulse is produced from the FBP signal from the deflection PB ASS'Y. The signal is used as
the IC304 switching signal. Since the FBP signal is delayed by the pulse cross signal, the H blanking pulse is also
delayed, and the pulse cross signal can be produced.
