QUATTROCANALI | SERVICE MANUAL

6. Disassembling Procedure

6.1 Removing the Amplifier’s Cover

The Quattrocanali & Duecanali feature a cleverly engineered
opening mechanism, there is no need to remove the screws
completely in order to open the amplifier’s cover.

Untighten the screws by 3 complete turns, 2 on each side.

Slide the side wings towards the back, releasing them from the amplifier’s chassis.

Gently pry the Front Panel slightly in order to completely expose
the top cover’s front side.

Gently remove the top cover.
