Caution: The circuit board contains many capacitors that could cause serious injury. Use a capacitor discharge probe to safely rid the capacitors of dangerous charges.

Wearing electrically insulated gloves and rubber soled shoes while working with and near the capacitors ensures greater safety and protection against electric shock. See iFixit's Project Safety page for additional safety information.

Note the 4 large flat head machine screws which hold the clamps on the opposite side; remove them with a #2 phillips head screwdriver.

The clamps are meant to hold the audio amplification PCB's IC's to the common heat sink; they ensure proper contact between the heat sink and the IC's through the ceramic thermal paste.
