Delta 60 Integrated amplifier handbook

Internal Fuses

Loudspeaker fuses

These are 2 amp fast blow 20mm x 5mm diameter in all

models. 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

(less than 4 ohms)

run into a short circuit

used to drive two sets of low impedance loudspeakers at once.

They are user-replaceable and two spares are provided.

However, if they blow consistently without any of the above conditions

being apparent please consult your dealer. Do

not

replace with a fuse of

greater value than 2 amps (or with a 'slow blow' or 'anti-surge' fuse) since

this will endanger the amplifier and your loudspeakers and invalidate your

guarantee.

Mains fuse

The fuse type is 1.25 amp anti-surge (slow blow) 20mm x 5mm

diameter in 220V and 240V models, 2.5 amp anti-surge in 100-120V

models. This fuse is designed to protect against faults in the amplifier,

transformer and mains switch. It is not user-replaceable. If this fuse blows

there is probably a fault, and the amplifier should be returned to your dealer.

Removal of top plate

In order to inspect or change fuses, or to reach the cartridge

loading module pins, you will need to remove the top plate 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 top plate unscrew the two black headed screws

at the top of the rear panel using a No. I 'Pozidriv' screwdriver (see figs.

1 and 3). Then lift the top plate vertically and pull it backwards slightly to

release it. Replacement is simply the reversal of this procedure.
