‘Supper' the tonearm elevated over the platter
with one hand to avoid strain and withdraw the
‘carrier with the other hand. Turn the carrier
over and peel off any adhesive tape used to
hold the coloured leads during transit.
When removing tho cartier with a cartridge
fitted, support the tonearm well clear of the
operating controls to avoid risk of damage to
the cartriage.
2 ATTACHING THE CARTRIDGE TO THE
CARRIER
(a) Secure the cartridge to the carrier by pass
ing a pair of screws through the cartridge
mounting (see ‘Note’ below), then screw:
ing them into the throaded holes in the
locking plate which slides in the channel
fon the opposite side of the carrier. The

3 ALIGNING THE CARTRIDGE
Slide the carrier into the slots in the clear
plastic eetting gauge. Take care that the stylus
{does not catch on the gauge as the cartridge
enters
The stylus tip must be vertically above the point
lat which the lines on the gauge cross. If it Is
not, move the cartridge until it is correctly
aligned.
4 CONNECTING THE CARTRIDGE
When the alignment is satisfactory, tighten
both foxing scrows, remove tho gauge, ané cor
rect the insulated leads on the earner by push
ing their tage onto the cartridge output pine.
Use the following colour code in conjunction
with the cartridgo manufacturer’ inetructione:

Set these as instiucted in the following sec-
tions.

Centre line is at 0 on the tonearm and the
magnetic shield (diagram 14) 80 that its red
Tine is at 0 on botn scales,

that it pivois freely. Take care to provent the
stylus from touching the rubber mat.
3 Wing the counterbalance weight backwards
fF forward until the tonearm is in balance
TONEARM ANTISKATING DEVICE
‘An anti-skating control is necessary to offset
‘the normal tendency of the tongarm to move
(skate) across the record toward the centre
As the record revolves, with the arm tracking,
‘an inward skating force is created, which must
‘be counteracted by an equal force in the
‘opposite direction. This minimises wear on the
inner side of the groove, premature damage to
the record, and sound distortion. The skating
force is directly rolated to the stylus force sot
for the cartridge.
‘The simple but ingenious anti-skating control
utiizes the wellknown magnetic principle that
like poles repel each other. This results in the
elimination of mechanical linkage. A ceramic
disc magnet is mounted on the pivoting tone-
farm gimbal and another affixed above it on the
Calibrated tonearm pivot bracket. A ferrous
metal shield, slides between the two magnets,
to sot the ant-skating force desired. When the
shiold is between the to!al areas of the mag
with the stylus tip at the height of the top
face of one record on the platter.
4 Return tho tonoarm to ite rest, and move the
locking lever to LOCK.
5 Set the stylus force to that recommended by
the cartridge manulacturer by moving tho
stylus force weight forward unt its centre

nets, they have no effect on each other, since
the shield blocks the magnetic flux. Hi
1a the shield is moved outward, it exposes the
magnetic field, creating a controllable amount
fof magnetic ropulsion. This, in tim, exerts. a
measurable torsional force on the tonearm, as
the two magnetic poles push apart, creating
the correct amount of antiskating force
desired, as indicated on the roading scale.
SETTING THE DEVICE
1 For a cartridge with a conical (spherical)
‘stylus tip. Move the magnetic shield along
the transparent tonearm mounting bracket
until the red calibration line on the shield
is ata pasition on the ‘conical’ scale cor
responding to the stylus force. If, say, 2

‘move the slider to the figure 2 on the scale
2 For a cartridge with an elliptical stylus tip.
Proceed in the same way, but use the
‘elliptical’ scale on the bracket.

GENERAL ADVICE
1 Keep the cartridge stylus clean and replace
it when worn. Your dealer will give further
advice on this.
2 Store and clean records as their manutac-
turers recommend. Do not leave records on
the turntable for long perieds after use
3 Do not switch on unless thera is at least one
record on the turntable.
4 Do not hold or turn the platter counterclock-
5 Always allow the unit to switch itself off, or
switch it off manually by one of the operating
Controle. 1 the power supply is disconnected
during play, the rubber intermediate wheel
will remain ‘under pressure and may be de-
formed after a length of time in this con
dition.
SETTING THE FINE SPEED CONTROL
Set the black marker on the control ting to the
Contre of the scale; this is sufficient for most
urposes. However, if an even more accurate
‘Setting is required, proceed as follows:
While playing a rocord ae described overleat,
look at the markings seen tnrough the strobo-
‘scopic viewing window at the front of the unit.
When playing at the 33" selting. the row of
black and rod bars further from the platter will
appear stationary when speed is exactly 33),
rev/min. Similarly, at the °45' setting the row
Cf bars nearer the’ platter will appear Stationary
at exactly 45 rev/min.
6 If the cartridge has mofe than one stylus,
make sure that the correct one is presented
for the record to be played.
PREPARING THE UNIT FOR USE AFTER

ADDITIONAL USES OF THE CONTROLS
Cue and Pause
The tonearm can be raised while a record is
Playing by using the cue control tab to LIFT,
land lowered again by moving it back to PLAY.
This foaturo is particularly useful for reposting
oF passing over any passage of music, and to
interrupt play (pause) for a short timo without
‘switching off
Repeat
[A ingle record being played automatically, or
the last record of a stack, can be replayed by
‘moving the automatic control tab to START
before the tonearm ifs at the end of ine
record.
AUTOMATIC RECORD COUNTER
The automatic record counter is designed to
registor evory time the tonearm returns over its
rest. The tonearm, after tracking freely, moves
tho ratchet whool, chown in diagram 21,
through a small arc causing the red pointer to
‘move a small amount up tho scalo on the faco
of the gimbal surround
The gearing of the ratchet whee! is such that it
will fake some 1600 cycles of the tonearm for
the pointer to move from the bottom of the
scale to the top. The scale itself Is quartered,
50 that the first mark reprosonts. about 400,
cycles, the second 600 cycles and the third
approximately 1200 cycles. The fourth is sub-
divided by red marks, each representing a
furthor 100 cycles.
The automatic record counter is designed as a
useful reminder to check the condition of your
stylus. Its not designed to indicate when the
Stylus should be changed,
Reject
Any record of a stack (oxcopt the last), can
be rejected by moving the automatic control
tab to START. To roject a single record or the
last of a stack move the tad to STOP.

‘generally faster rate of wear if an elliptical

To use the automatic record counter effec:
tively, set the pointer to the lowest calibration
line when starting out with anew stylus, also
when the pointer reaches the top of its scale,
Having set the pointer, the counter can be used
to monitor the number of tonearm cycles, and

of the stylus may be made,

LUBRICATION
‘The bearings of the intermediate wheel, motor
and platior aro of oilvetaining material and
rarely require lubrication. However, when the
‘hood is apparent, remove the platter and apply
light oll, of the type used on sewing
machinos, to the points mentioned below.
‘TO REMOVE THE PLATTER,

the inside edge of the rubber mat and prise out
the plastic centre disc with a small scraw-
driver. With the seme tool, pull off the wise
