Turns on when base goes Hi, and turns on CD servo 7.5 volt supply.
When base of Q13 goes Hi, AVR output turns on.
When base of Q15 goes Hi, AVR output turns on.
Turns SW16V AVR on and off. Turns on when base goes Hi,
and turns on the SW16V output.
SW16V output turns on when Q18 base goes HI.
Turns on when base goes Hi, and turns on the 11 volt LED supply.
Turns on when base of Q21 goes Hi and turns on the 11V output.
Turns on when base goes Hi, and turns on FAC11V.
Turns on when base of Q24 goes Hi, and turns on FAC11V output.
Turns on when base goes Hi, and turns on the WMA DSP 5 volt supply.
Turns on when base goes Hi, and turns on LED of CD entrance.
During AM operation, base goes Lo and turns on.
During FM operation, base goes Lo and turns on.
During FM/AM operation, base goes Hi, and Q52 or Q53 turn on and off.
