MAINTENANCE
The bearings in the motor and intermediate wheel
are
of the oil retaining type and rarely need lubricat-
ing. When the need for oil is apparent, remove the
turntable and while holding the
rubber tyred inter-
mediate wheel
out of the way, lubricate the motor
and pulley bearings with alight grade of machine oil.
Carefully remove every trace of oil from the driving
surfaces before replacing the turntable.

with the fingers and lifting with aslight twisting motion.
FITTING TURNTABLE.
Make sure that the speed change knob is in the
neutral position to release the tension on the
intermediate wheel.

VOLTAGE AND FREQUENCY.
The "GARRARD" Model TA/Mark II Four Speed
Record Playing Unit
is suitable for use on 100/130 and
200/250 volts, at either 40, 50 or 60 cycles according to
the motor pulley supplied and the links on the terminal
block should be set to the correct position
to correspond
with the voltage
of the power supply as shown in
Diagram
5. Amotor driving pulley can be supplied for
40, 50 or 60 cycle power supply as required.
The motor should be earthed by connecting alead
from the earthing tag located under one of the
motor
end cover screws, to agood earth connection.
If the unit is to be used with aradio set or amplifier
having aUniversal
(ACjDC) chassis, or if the
reproducer is abattery set coupled to aUniversal H.T.
battery eliminator, it
is essential to make sure that
isolating components (condensers or transformer) are
incorporated in the pickup input circuit in the set other-
wise the pickup circuit can become "live."
Should the isolating components
not be included
in the set they should be fitted externally in series with

SPEED.
The motor on the Model TA/Mark II is designed
to give the desired turntable speed within close
tolerances. Should the turntable run excessively fast
or slow, then the motor pulley should be examined to
see if it IS the correct one to suit the frequency of the
power supply.
The motor pulley is colour finished as follows to
distinguish the three
types:-
NICKEL
BRASS
COPPER
SPEED VARIATION.
It is essential that the driving surfaces of the
motor pulley, the
rubber inter-wheel and the turntable
rim, should be kept absolutely free from oil
and
grease. This is the first point which must be checked
if the turntable speed varies
and the pulley and inter-
wheel should be cleaned with a dry cloth if oil on the
driving surfaces
is suspected.
MOTORS.
If the motor fails to start when the unit is switched
on, first check the power supply
and ascertain if
current
is reaching the motor terminals. If correct.
switch off the power supply and examine the terminal
block
and see that the leads and screws are tight; also
examine the switch contacts which are accessible by
removing the cover from the switch. (Diagram I). Clean
and adjust if necessary.
Thick oil should not be used to lubricate the
motor
bearings as it will cause the motor to appear weak
or fail to start
and it will then be necessary to dis-
mantle the
motor and clean away all traces of the
thick oil.
It is essential to lubricate the motor bearings
with agood quality thin oil such as sewing machine oil.
PICKUP.
Two types of stylus are necessary for playing the
different types
of records. Astylus having apoint
radius of .0025"
is required for the standard 78 r.p.m.
(coarse groove) records
and one with apoint radius of
.001" for microgroove (fine groove) records.
The Model TAl Mark II is designed to take avariety
of turnover pickup heads or single purpose plug-in
pickup heads to suit the individual owner's require-
ments
and care should be taken to ensure that the
correct stylus
is presented to the record.
Turnover pickup heads are correctly set when the
speed
of the record to be played appears on top of
the turnover knob. If there is an arrow on the knob
it indicates the direction in which it should be turned
when achange
is required.
It is recommended that the stylus pressure be
checked periodically with a
Garrard Stylus Pressure
Gauge. Also its use
is essential should another type of
pickup be used other than that supplied with the unit,
as some adjustment
for the difference in pickup weight
may be required.
The stylus pressure adjusting screw is located .at
the rear
of the pickup arm, and to adjust the stylus
pressure, the knurled
knob should be turned to give
either an increase
or decrease in spring tension.
Page Seven
www.radio-workshop.co.uk

The maximum recommended stylus pressure for
all types of records is 10 grammes. Should trouble
be experienced with the reproduction from apickup,
the head should be returned for examination to the
manufacturer whose name
or trade mark appears on
tbe cartridge.
Pickup cartridges must not be opened
or the
manufacturers will disclaim all responsibility.
NOTE.
Acontinuity test cannot be carried out on crystal
pickups with
an ohmmeter.
Should there be tendency for the pickup to track
incorrectly, check the pickup stylus pressure
and adjust
as explained above if found other than
10 grammes;
also make sure
that the flexible lead to the pickup is
not twisted or held in such manner so as to prevent
the free movement
of the pickup arm, and see that
the associated levers are free.
AUTO STOP MECHANISM.
The auto stop mechanism for automatically switch-
ing off the
motor at the end of arecord is of the
velocity type and
is of aspecial design to be very light
and sensitive in operation. It is set to commence
operation when the stylus reaches a
2t"radius. The stop
operates by the
auto stop lever being raised by asmall
cam attached to the turntable spindle when the pickup
arm runs in on the record run-off-groove. The auto stop
lever, on being lifted, trips the catch lever and operates
the
auto stop. If the auto stop fails to operate it may
be caused
by the auto stop lever being too low and it
should be raised
by giving the auto stop lever adjusting
screw (Diagram
1) about half aturn in aclockwise
direction.
GARRARD STYLUS
PRESSURE
GAUGE
MODEL SPG2
Page Eight
This Gauge, having a range of 0 to 15 grammes, provides a
simple, accurate and inexpensive instrument for measuring the
stylus pressure of pickups for playing Microgroove (Fine
Groove) Records.
The slide off base. containing a spirit level for checking the
level of the turntable, should be filled when used with a record
changer, this will give the pressure l" above the turntable
face, this being the mean reading fer a stack of records as
used on record changers.
With the base removed the reading is taken as near as possible
to the turntaole top, the stylus pressure thus being measured
atthe equivalent height of one record.
To prevent excessive record wear when playing Microgroove
(Fine Groove) Records, the turntable should be quite level and
stylus pressure not exceed 10 grammes.
Preted your records by making a periodical check of stylus
pressure and adjustin~ counter-balance if necessary. ObtaIn-
able with or without slide off base.
EVERY GRAMOPHONE ENTHUSIAST AND RADIO SERVICE
MAN SHOULD POSSESS
ONE OF THESE GAUGES.
