General Information

This manual serves for Garrard Models 50 Mk II, S.L.55,
60 Mk II and S.L.65. These units have the facility to play
records automatically or they can be used manually to play
single records.

Models 50 Mk II and S.L.55 are similar, having large
diameter steel turntable and diecast aluminium pickup arm
with fixed counterbalance weight. Pickup leads terminate at
a tag strip or a phono socket/muting switch. The major
difference between these two units is that Model 50 Mk II
may be fitted with either a two or a four pole induction
motor, whereas Model S.L.55 is fitted with the Garrard
Synchro Lab motor.

Models 60 Mk II and S.L.65 are also similar to each other.
They have a diecast turntable and tubular, counterbalanced
pickup arm with bias compensator. Pickup leads terminate
at a phono socket or muting switch. Again, the major differ-
ence between these two units is that Model 60 Mk II is fitted
with the Garrard Laboratory Series four pole induction
motor, whereas Model S.L.65 is fitted with the Garrard
Synchro Lab motor.

The Garrard Synchro Lab motor uses induction principles
to attain running speed: at that speed a magnetic element
then locks the rotor so that it runs synchronously with the
frequency of the power supply.

Common to all four units is the cueing device and auto
mechanism, and service engineers will note that these units
have been developed from Models 50 (also known in some
areas as 40 Mk II) and A.T.6o.

All models will play up to eight mixed records automatic-
ally of 7, 10 or 12 diameter. A short manual spindle
is supplied for single record play and large centre hole
records may be played automatically using adaptor L.R.S.
20 (optional extra). A single play adaptor is also available
for use with large centre hole records.

These units also feature plastic foam damped spring sus-
pensions and a plug-in pickup head, designated M7, which
will accept a wide range of cartridges.

The units are made in a number of different colour finishes
and with differing turntable mat trims. Synchro Lab motors
can be supplied to run on 110/130 volts A.C. only or for
110/130 volts and 220/250 volts A.C. The latter version is
fitted with a voltage changeover block attached to the motor.
(Induction motor voltages 100/130 volts A.C., or too/13o
volts and 200/250 volts A.C.)

The Synchro Lab and 4-pole induction motors are suitable
for 50 or 60 Hz according to the motor pulley fitted. The
z-pole motor does not have a removable pulley and a
different motor is required for 50 or 60 Hz supply.

These units play automatically when the records are of the
same speed and record groove type. They can be stopped
and started without rejecting the record being played, or
records can be rejected as desired. Switch off is automatic
after playing the last record. The cueing device permits the
pickup arm to be accurately positioned on a record by
manual means and also allows play to be interrupted when
used as a pause control.

Before using these record changers make sure that the power
supply is as labelled on the motor. If the unit is connected
to an amplifier whose wiring is not isolated from the power
supply, isolating components should be incorporated in the
pickup circuit, otherwise the pickup circuit can become live.

Always disconnect the power supply and protect the pickup,
when servicing a unit.

In some cases such as those associated with pickup and
power connections, components for these models may vary
(other than as illustrated) due to the wide variety of cus-
tomers specifications. Therefore, when referring to these
models, obtaining spares etc., always quote the code stamp-
ed on the inspection label, unless a full description can be
given. (See parts list.)

The information in this manual applies to all models covered
except where otherwise stated or illustrated.

Garrard units are made to play records complying to 8.8.
1928 : 1965 and I.E.C. Publication 98, also similar standards.

FAULT

CAUSE

CORRECTION

Fails to switch off when last
record has played, or switches
off without playing a record.

1.

Record overarm
(3) not free.

spindle

Excessive friction on con-
trol lever (66).

Switch off lever on lower
casting (78) stiff.

Check that the record overarm (3) when in its innermost
(i.c. operating) position will drop freely under its own
weight when lifted up. If not, remove spring clip (8!),
spring (3E) and washer (3F) if fitted, and pull out the overarm
(3). Clean it, oil its spindle and replace components, check-
ing for freeness. To reset the overarm (3) check that the
rubber washers at the top of the spindle are right against
the upper casting (40). Then with the overarm in its operat-
ing position and no records on the record spindle (31), check
that the end of the overarm (3) is not more than 52 below
the record spindle step. Make sure the record spindle (31)
is located properly.

Check that the movement of the control lever (66) is not
restricted and its associated levers are not damaged. Should
any lever be damaged, repair or replace it. Grease the end
of control lever (66) that operates switch lever (72).

Check that this lever moves freely between unit plate
and lower casting (78). When the tail of this lever is
moved away from the pickup arm, it should return under
spring pressure. For the switch off mechanism to work
properly, the switch off lever tail must be square with the
unit plate. If it has been bent in transit, carefully bend it
square again. Apply grease as stated under Maintenance
and in diagram 11.

Pickup consistently lands too

far in or out.

Pickup dropping position
requires adjustment.

Selector lever nut (83)
loose.
Selector moulding (I) dam-

aged or out of position.

See Pickup Dropping Position under Service Adjust-
ments.

Check that nut (83) is tight to ensure that selector lever (82)
is securely held.

Check that the selector (1) arm moulding is not damaged.
Check its position thus:- With no record on spindle step
(31) and power turned off, switch control to Auto and
revolve the turntable clockwise by hand. Watch record
spindle pawl as it moves across the record spindle step. Stop
revolving the turntable when the pawl reaches its outermost
position. Then with the overarm (3) in its operating position,
check that the tip of the selector arm is between 4.3 and
4} radius from the turntable centre. Also, move separately
a to", then a 12 record slowly down the record spindle and
make sure that the selector lever (82) catches into its to
and 12 selecring positions. If the selector (1) is faulty, it
should be replaced.

Erratic selection of records.

I.

Selector
loose.

lever nut (83)

Selector spring (84) weak
or incorrectly assembled.

Friction link (92) requires
lubrication.

Tighten nut (83).

Move overarm (3) to Operating position, then move selector
arm (1), by hand, away from the turntable centre; it should
return by light spring pressure. If it does not, check that
seleetor spring (84) is correctly assembled to lower casting
(78) and selecror lever (82). If it has stretched, replace it.

Make sure that the friction link (92) is not damaged; grease
it along its slot.
