8 Fuse
The circuitry of the amplifier is protected from damage
by an automotive-type fast-blow fuse. If fuse replacement
is necessary, use only fuses of the same ampere rating
as originally supplied with the unit. The use of fuses with
incorrect ratings may cause serious damage to the amplifier.
If fuses blow consistently, carefully check all electrical
connections to the unit.
