Detects temperature of the heat sink, and protects bias current drift. Detects over-current, and limits the power stage current.

Detects P.CON-ON, and turns Q47 on or off. Supplies power to IC5. Turns Q49 on or off.

The detected over-current stops IC5's working. When over-voltage puts on BATT, Q53 turns P.CON. off. Supplies + and - 15V power.

Makes an input signal 6 more dB signal, and cancels automobile noise.

Oscillator for DC/DC converter.
