Cleaning
When cleaning the stereo 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 stereo
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 stereo
power amplifier is completely dry.
Maintenance
To clean the audio connections
The audio sockets on the back of the stereo 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.
