There are two 5x20mm glass fuses located on the upper
deck power supply board as shown below. One fuse is for
the standby power supply and the other is for the main power
supply transformer. The values for these two fuses are as
follows:
120V models
Stand-by fuse (F2): F 500mA 250V
Part numbers: Littelfuse 217.500 Littelfuse 217.500
Main PSU fuse (F1): F 1.6A 250V
Part numbers: Littelfuse 217 01.6 Littelfuse 217.800
Before attempting to change fuses, disconnect all cables
from the SP3, especially the power cord. Then remove all
the screws from the top and left & right sides that hold the
top cover in place. Remove the top cover by sliding towards
the back of the unit and then lifting up. Be sure to replace all
screws when replacing the top cover using no more that 16
inch-pounds of torque.
When removing screws from top cover use only the proper
driver, a Torx #8, and do not use excessive force as it may
damage the screw head. If the screw does not move tap
lightly with a hammer to loosen the threads. If this doesn't
work, please refer the unit to qualified service personel.
