6. MAINTENANCE
Only or persons should attempt any service or maintenance of the amplifier.
The surface of the Heat Sink may become covered with dust over time, reducing it’s efficiency. The heat sink
should be cleaned as part of routine maintenance.
Along with the rear panel mains fuse, there are four (4) rail fuses provided internally in the unit. These
rail fuses are in series with the positive and negative output supply to each amplifier channel and
provide overall protection for the output stage. If the amplifier is subjected to heavy use such as short
circuits, these fuses will eventually fatigue and may require replacing.
NOTE
Make sure the unit is and is unplugged from the mains. Give the main filter capacitors time to discharge before
removing lids and inspecting the fuses.
You should replace any fuse if it’s element is . Only ever replace with the same type fuse
and current rating.
When checking for a failed fuse, do not rely on visual inspection alone. You should use an ohm meter to check
continuity.
