NOTE
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 ANY SUBSTITUTE FUSES WITH DIFFERENT RATINGS, 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
.
To remove a blown or suspect fuse from its fuse holder, use only a number 2 Phillips
screwdriver to prevent damage to the fuse holder. Simply press lightly on the fuse-holder cap
and turn counterclockwise. The cap will "pop" out after several turns. To replace the fuse-
holder cap, once the fuse has been replaced and properly installed in its seat on the fuse-
holder cap, press lightly inward, once the fuse and cap have been inserted in the fuse-holder
body, and turn the cap clockwise until it is firmly seated in the fuse-holder body. Be certain
not to cause cross-threading of the fuse-holder body and cap to prevent damaging the fuse
holder.
DO NOT FORCE THE FUSE-HOLDER CAP INTO THE THREADS
. Seating of the
cap in the fuse-holder body should be easily accomplished without excessive force.

the unit off.
