Fuses
The AC line is fused to protect the power transformer. This fuse will not fail in
normal operation. Failure of the fuse is a symptom of a more serious problem, so the
unit should be taken to a qualified service center. IN NO EVENT SHOULD THE
FUSE BE REPLACED WITH A FUSE OF DIFFERENT TYPE OR RATING
THAN THAT SUPPLIED BY THE FACTORY
MV75A only: The power supply to the output stages of the MV75A are fused to
prevent damage to the amplifier in the event of failure of an output tube. The fuse
holders are located adjacent to the output strips. When one of these fuses opens the
corresponding channel will be dead. An LED adjacent to the fuseholder will light to
indicate a blown fuse. Should the fuse blow, the output tubes in that channel are
suspect and should be replaced.
