Check list

Should you have any difficulty in operating your amplifier,

check the following before suspecting that a fault has developed.

No power and LED not illuminated. Check that;

1 the mains supply is connected and that the mains lead is

fully home in the mains inlet socket at the rear of the amplifier

2 the mains is switched on and that the power switch on the

front panel is depressed and has fully latched

3 the fuse in the mains plug has not blown and that the mains

socket in the wall is live (test with another item/appliance)

Power on and LED illuminated but no output from

the amplifier. Check that;

1 the amplifier is connected to the desired input and that the

correct input on the amplifier is selected

2 the loudspeakers are connected correctly to the amplifier

3 if you have your loudspeakers connected to the outlets

marked 'Switched (SP2)', that you have also depressed the switch marked

SP2 on the front panel

the volume control is not set to minimuim

5 if disc is selected, that the cartridge selector switch is set to

the correct type of cartridge

NB Do not operate this switch with the volume control turned up

6 if CD is selected your machine is playing a CD

7 both speaker fuses have not been blown by a previous user

Power on and LED illuminated but output from one

loudspeaker only. Check that;

1 both loudspeakers are plugged into the correct amplifier

outlets. Note, the amplifier may appear to play in mono if the loudspeakers

are inadvertently plugged into the direct and switched outputs of one

channel

2 both the left and right channels of the selected source are

connected correctly and the input wiring is not faulty (check by swapping

over the left and right input connectors)

If in doubt contact your dealer

3 one section of the volume knob is not set to minimum

4 one speaker fuse is not blown

Loud hum heard through loudspeakers when disc is

selected. Check that;

1 the ground lead from the turntable (if fitted) is connected

firmly to the ground terminal on the rear of the amplifier

2 the amplifier is correctly earthed via the mains lead

3 your cartridge is not sited directly above your

amplifier's transformer

(Move the amplifier away and check if the hum level changes).

4 other transformers in the vicinity are not radiating into

the Delta 60

Loud hum heard through only one loudspeaker

when disc Is selected. Check that;

1 The ground wire is not faulty within the respective

channel's lead. This is easily checked by swapping over the leads and

checking if the hum moves to the other channel.

2 The headshell leads connected to the cartridge on the

respective channel are not faulty or loose. If in doubt please consult

your dealer.
