Pick up the fuse with pliers and check that the glass
envelope is dark or black, indicating a blown fuse.
Remove it and simply install a new fuse in the holder.
Once the new fuse is inserted, push back the fuse
holder and turn it 180° clockwise until you feel a
slight click.
You’re back in business!
Fuse ratings are:
110-125vAC: 6.3 amps T type.
220-240vAC: 3.15 amps T type.
T type means “Temporized”. Do NOT use the so-
called "slo-blo" type, especially the kind with coil-
wounded filament. The filament in the fuse glass
envelope must be seen as a thin STRAIGHT wire.
Never use improper fuse ratings. Very great fire
risk!
Now you can restore the amplifier back to its hori-
zontal position and put the glass cover on, as de-
scribed in chapter 6.3. "User parameters".
Connect again all your cables, without omitting the
loudspeakers , and power ON your NHB-108 model
one .
Now you are ready to enjoy some more good mu-
sic, compensating all that tiring physical effort you
have just put in…
Although the above procedure could seem rather
long and complicated, you will see that it is a sim-
pler task to perform than to explain.
Anyhow, if you carefully respect all advice and
warnings
, you should never encounter such prob-
lems of blown fuse(s).
