Fuses
Loudspeaker fuses
These are 1.6 Amp (or less) fast blow 20mm x 5mm diameter fuses. They may blow if the
amplifier is:
- run continuously at high level into the correct loudspeaker load
- run at high level into a loudspeaker of too low an impedance (“4ohms” or less)
- run into a short circuit
They are user-replaceable and two spares are provided. However, if they blow consistently
without any of the above conditions obtaining please consult your dealer. DO NOT replace with
a fuse of greater value than 1.6 Amps (or wth a “slow blow” or “anti-surge” fuse) since this will
endanger the amplifier and your loudspeakers and invalidate your guarantee.
Power supply fuses
These are 3.15 Amp fast blow 20mm x 5mm diameter fuses. They are NOT USER-
REPLACEABLE and spares are not supplied. If these fuses blow, there is probably a fault in
the amplifier - do not change the fuses but consult your dealer.
Mains fuse
This is a 1 Amp anti-surge (slow blow) 20mm x 5mm diameter in all models. This fuse is
designed to protect against faults in the amplMer, transformer and mains switch. It is not
normally user-replaceable. However, should it blow during a continuous period of very high level
music, or on amplifier switch-on, it may be replaced once only WITH A FUSE OF THE
CORRECT TYPE (one spare is provided). If a second fuse blows within a short period then
there is a fault, and the amplifier should be returned to your dealer.

Removal of wooden cover
In order to inspect or change fuses, or adjust the tape replay level controls, you will need to
remove the wooden cover from the amplifier.
BEFORE REMOVING THE COVER, ALWAYS SWITCH OFF THE AMPLIFIER AND
DISCONNECT FROM THE MAINS SUPPLY.
Note that the mains fuse remains live whenever the amplifier is plugged into the mains, even
when the amplifier power switch is in the off position. To remove the cover unscrew the two
black-headed screws towards the rear of the side panels using a No.l “Pozidriv” screwdriver.
Tlien slide the cover forward as far as it will go (approximately 15mm) and lift it vertically
upwards. Replacement is merely a reversal of this procedure.
