TR for comprising Darlington connection
Power supply is input from No. 2 pin and switching output is made from No. 3 pin.
Going via choke coil, it becomes S7V power supply output.
Input is made on No. 3 pin and output is made from No 6 pin.
When QP2 is ON, input is made to the emitter. Mute circuit driving power supply is output
from the collector.
This is a TR for switching QP2. Therefore, the logic is inverted and when the TR comes
ON, muting is OFF, and when the TR comes OFF, the muting is ON.
When this TR is ON, base current of QP21 is shut off. QP21 is OFF and switching power
supply is ON.
When Z_MUTE signal in the base of this TR is active, (H on no signal), QP1 is turned ON
and the mute circuit is driven.
/P_ON in the base becomes L when the power switch comes ON. Therefore, it is H when
the power is OFF. When this happens, QP3 is forced to go OFF and muting is driven.
On the base of this TR, power switch triggered /P_ON signal comes in. When this is L, and QP22
is turned ON, base current of QP20 is shut off. When QP20 is OFF, switching power supply is ON.
At the time of reduced +B1, base current is shut off and the circuit goes OFF.
When this TR is ON, switching power supply is OFF.
When this TR is ON, switching power supply is OFF.
When this TR is ON, base current at QP20 is shut off. This means QP20 is OFF and
switching power supply is ON.
