PF-350 / PF-500 / PF-800 Bass Guitar Amplifier Fault/Thermal Considerations: As an amplifier works, it produces heat. The higher the signal level, the louder and hotter it gets. It is important to dissipate the heat as quickly as possible. This results in increased reliability and longevity for the amplifier. The amplifier module is mounted on a large heatsink, which is cooled by convection where cool air is drawn through its fins, carrying the heat away.
Flip-Top Instructions: It is accomplished in five simple steps: Step 3: set the cabinet top handle-side down on the top of the cabinet. The amplifier should now be on the top, rightside up, with the front of the amp and the front of the cabinet facing the same direction. Step 1: loosen the latches on each side of the cabinet. There are two latches on each side, four total. Step 5: rock out like there is no tomorrow! So you’ve made it this far and you are now ready to flip your lid...
