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.
