Hafler XL-600 Owner's Manual - Factory Service &
If the pilot lamp does not glow when the amplifier is turned
on, and it is not due to an excessive temperature condition,
then either the internal 15 ampere line fuse is blown, or the
circuit breaker or fuse supplying the AC power has inter-
rupted power.
If no sound is heard once the relay engages and an input
signal is applied, check all input and output connections,
as well as the back panel speaker protection fuses.
In addition to the internal 15 ampere line fuse, there are
four 10 amp rail fuses, None of these internal fuses are
intended to be user replaceable, and a blown condition
usually indicates a need for professional service.
