Fuses - Bryston SP3 Owner's Manual

There are two 5x20mm glass fuses located on the up-
per 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:
120Vac models
Stand-by fuse (F2): F 500mA 250V
Part numbers: Littelfuse 217.500
Main PSU fuse (F1): F 1.6A 250V
Part numbers: Littelfuse 217 01.6
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.
