Cleaning
When cleaning the multi channel power amplifier bear in mind
that the front of the unit is brushed aluminium and the case is
metal.
Disconnect the power cord before cleaning the unit.
Note: Do not use abrasive cleaners on any part of the multi
channel power amplifier.
To clean the case
● Use a slightly damp cloth.
Ensure that no water is allowed to get inside the case, and do
not reconnect the power until you are certain that the multi
channel power amplifier is completely dry.
Maintenance
To clean the audio connections
The audio sockets on the back of the multi channel power
amplifier are gold-plated and need no cleaning if gold-plated
phono plugs are used. Otherwise, it is recommended that you
unplug and reconnect the plugs at least once a year. A
proprietary contact cleaner can be used to some advantage.
To change the mains fuse
Fuse
Spare
● Remove the mains connector, and pull out the drawer next to
the power input to access the fuses.
Before replacing a blown fuse, if possible ascertain the cause of
the failure.
The fuse drawer includes a spare fuse. This should be replaced
by one of the same rating.
