protect the electronic circuits in the GFA-565, it is recommended that it be replaced only with
one of the fuses listed in the table below. Please note that the fuses listed are for operation
of the amplifier on 120VAC/60Hz. For the correct fuse values to operate the GFA-565 on
other voltages and frequency, please consult the Service Manual for this amplifier available

Whenever the POWER switch on the front panel is turned on and the amplifier is energized,
the POWER LED will glow. If turning on the amplifier does not cause the POWER LED to
glow, it may be an indication that the AC LINE FUSE is blown. Unplug the AC LINE CORD
from the AC wall outlet and turn the POWER switch off and check the fuse. If the fuse is
blown, replace it with one of the fuses listed in the table below, plug the amplifier into its
AC-wall outlet and turn on the amplifier. If after replacing the fuse, it blows immediately upon
turning on the amplifier (POWER LED does not glow), a failed electronic component or
other internal malfunction must be suspected. Make no further attempts at fuse replacement
or operation of the amplifier. Refer the problem to competent ADCOM-authorized
service personnel.
Before checking or replacing a blown fuse, make certain you UNPLUG THE AC LINE
CORD FROM THE AC WALL OUTLET TO PREVENT POSSIBLE ELECTRICAL
SHOCK.
The fuses listed above, and their time-current blowing points, have been carefully selected
and thoroughly tested to deliver optimal performance while still accomplishing their
protective functions. Replace the AC LINE FUSE only with one of the fuses listed above.
DO NOT USE
TIME-CURRENT CURVES OR VALUES. Failure to observe this precaution may cause
serious damage to the amplifier circuits, MAY CREATE A FIRE HAZARD, AND WILL
VOID YOUR WARRANTY.
