Maintenance

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.

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.
