Before accessing and checking the power fuse on your amplifier, first ensure that the amplifier is turned off and unplugged.
The power fuse on your PRS amplifier is located inside the power outlet housing and is accessible by using a small flathead screwdriver to remove the bottom compartment. In new PRS amplifiers, there will be a spare power fuse stored in the compartment.
Check the fuse by testing continuity with a multimeter.
If the fuse needs replaced, replace the power fuse with one of the same values described on the back of the amplifier.
