Parts List - Fender Deluxe 112 plus Service Manual

Diodes' CR9-CR12 make up a voltage clamp protection circuit. Q8 and Q9 make up a current limiting
protection circuit. If the output is shorted, the voltage at the emitters of Q10 and Q11 will increase. This
voltage is sensed through R100 and R107 and presented to the bases of Q10 and Q11. When Q10 and
Q11 turn on, the drive current and bias to the output transistors is removed, which shuts down the output
section of the amplifier.
The output signal feeds through the Headphone jack circuit, before driving the speaker. With headphones
connected to the headphone jack the speakers are muted.
