REMOVING THE PICKUP CARTRIDGE
Support the pickup arm 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 the carrier with a cartridge fitted, support the pickup well clear of the operating controls to avoid risk of damage to the cartridge.
FITTING THE PICKUP CARTRIDGE
The fixing screws and cartridge setting gauge provided enable a wide range of high quality cartridges to be fitted in their correct operating position in the carrier.
Great care must be taken when fitting the cartridge since it forms an integral part of the extremely precise pickup arm design essential to the exceptional degree of tracking accuracy.
TO FIT THE CARTRIDGE
- 1 Secure the cartridge to the carrier by passing a pair of screws through the cartridge mounting and the cartridge carrier, then screwing them into the threaded holes in the sliding locking plate which slides in the channel on the opposite side of the carrier. The screws must not protrude through the far side of the locking plate sufficiently to touch the setting gauge.
- 2 Tighten the screws barely sufficiently to hold the cartridge in place, then slide the carrier into the slots in the clear plastic setting gauge, taking care that the stylus does not catch on the gauge as the cartridge enters.
- 3 The stylus tip must be vertically above the point at which the lines on the gauge cross. If it is not, move the cartridge until it is correctly aligned.
A setting gauge is provided so that the cartridge may be assembled in the correct position on the carrier.
To fit the cartridge proceed as described below.
FITTING THE PICKUP CARTRIDGE CARRIER
Move the pickup arm locking lever to FREE, support the pickup over the turntable away from the operating controls with one hand, to avoid risk of damage to the cartridge, and press the cartridge carrier back into place in its slot in the front of the pickup arm.
STYLUS FORCE AND PICKUP ARM ANTI-SKATING DEVICE
Set these as instructed in the following sections.
4 When the alignment is satisfactory, tighten both fixing screws, remove the gauge, and connect the insulated leads on the carrier by pushing their tags onto the cartridge output pins. Use the following colour code in conjunction with the cartridge manufacturer's instructions:
Red – Right hand channel signal Green – Right hand channel ground White – Left hand channel signal Blue – Left hand channel ground
Note: If a cartridge has only three pins or tags, use the green lead, or green and blue joined together. Insulate and tuck away any lead not required.

Note: If a cartridge has only three pins or tags, use the green lead, or green and blue joined together. Insulate and tuck away any lead not required.
SETTING STYLUS FORCE
- 1 Move the stylus force weight so that its centre line is at 0 on the pickup arm and the magnetic shield (diagram 14) so that its red line is at 0 on both scales.
- 2 With the cartridge fitted, remove the stylus guard and move the pickup arm locking lever to FREE and move the pickup arm inwards so that it pivots freely. Take care to prevent the stylus from touching the rubber mat.
- 3 Wind the counterbalance weight backwards or forward until the pickup arm is in balance
with the stylus tip at the height of the top face of one record on the turntable.
- 4 Return the pickup arm to its rest, and move the locking lever to LOCK.
- 5 Set the stylus force to that recommended by the cartridge manufacturer by moving the stylus force weight forward until its centre line is at the mark on the pickup arm scale representing this force. The scale is calibrated up to 3 grammes in steps of 1/4 gramme.
PICKUP ARM ANTI-SKATING DEVICE
An anti-skating control is necessary to offset the normal tendency of the pickup 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 related to the stylus force set for the cartridge.
The simple but ingenious anti-skating control utilizes the well-known 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 pickup arm gimbal and another affixed above it on the calibrated pickup arm pivot bracket. A ferrous metal shield slides between the two magnets, to set the anti-skating force desired. When the shield is between the total areas of the mag-
nets, they have no effect on each other, since the shield blocks the magnetic flux. However, as the shield is moved outward, it exposes the magnetic field, creating a controllable amount of magnetic repulsion. This, in turn, exerts a measurable torsional force on the pickup arm, as the two magnetic poles push apart, creating the correct amount of anti-skating force desired, as indicated on the reading scale.
SETTING THE DEVICE
- 1 For a cartridge with a conical (spherical) stylus tip. Move the magnetic shield along the transparent pickup arm mounting bracket until the red calibration line on the shield is at a position on the 'conical' scale corresponding to the stylus force. If, say, 2 grammes stylus force has already been set, 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
- 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 manufacturers recommend. Do not leave records on the turntable for long periods after use.
- 3 Do not switch on unless there is at least one record on the turntable.
- 4 Do not hold or turn the turntable counterclockwise.
- 5 Always allow the unit to switch itself off, or switch it off manually by one of the operating controls. If the power supply is disconnected during play, the rubber intermediate wheel will remain under pressure and may be deformed after a length of time in this condition.
6 If the cartridge has more than one stylus, make sure that the correct one is presented for the record to be played.
PREPARING THE UNIT FOR USE AFTER TRANSIT
- 1 Remove the stylus guard, if one is fitted.
- 2 Turn both transit screws fully clockwise so that the unit floats freely on its spring mountings.
- 3 Move the pickup arm locking lever to FREE.
- 4 Check turntable speed as described in the next section.
- 5 Check that all three operating tabs are upright.
Reverse instructions 1, 2 and 3 before the unit is transported again.
SETTING THE FINE SPEED CONTROL
Set the black marker on the control ring to the centre of the scale; this is sufficient for most purposes. However, if an even more accurate setting is required, proceed as follows:
While playing a record as described overleaf, look at the markings seen through the stroboscopic viewing window at the front of the unit.
When playing at the '33' setting, the row of black and red bars further from the turntable will appear stationary when speed is exactly 331/3 rev/min. Similarly, at the '45' setting the row of bars nearer the turntable will appear stationary at exactly 45 rev/min.
If the appropriate row of bars appears to move clockwise, move the fine speed control towards the minus sign (-) until the bars appear to stop. If it appears to move counterclockwise, move the control towards the plus sign (+) until the bars appear to stop. The stroboscopic method of measurement is extremely precise.
The degree of control (approximately 3% above and below nominal speed) also enables a user with the faculty of 'absolute pitch' to set record speed to his complete satisfaction, since a total variation of almost a semi-tone is provided.
GENERAL ADVICE
- 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 manufacturers recommend. Do not leave records on the turntable for long periods after use.
- 3 Do not switch on unless there is at least one record on the turntable.
- 4 Do not hold or turn the turntable counterclockwise.
- 5 Always allow the unit to switch itself off, or switch it off manually by one of the operating controls. If the power supply is disconnected during play, the rubber intermediate wheel will remain under pressure and may be deformed after a length of time in this condition.
6 If the cartridge has more than one stylus, make sure that the correct one is presented for the record to be played.
PREPARING THE UNIT FOR USE AFTER TRANSIT
- 1 Remove the stylus guard, if one is fitted.
- 2 Turn both transit screws fully clockwise so that the unit floats freely on its spring mountings.
- 3 Move the pickup arm locking lever to FREE.
- 4 Check turntable speed as described in the next section.
- 5 Check that all three operating tabs are upright.
Reverse instructions 1, 2 and 3 before the unit is transported again.
SETTING THE FINE SPEED CONTROL
Set the black marker on the control ring to the centre of the scale; this is sufficient for most purposes. However, if an even more accurate setting is required, proceed as follows:
While playing a record as described overleaf, look at the markings seen through the stroboscopic viewing window at the front of the unit.
When playing at the '33' setting, the row of black and red bars further from the turntable will appear stationary when speed is exactly 331/3 rev/min. Similarly, at the '45' setting the row of bars nearer the turntable will appear stationary at exactly 45 rev/min.
If the appropriate row of bars appears to move clockwise, move the fine speed control towards the minus sign (-) until the bars appear to stop. If it appears to move counterclockwise, move the control towards the plus sign (+) until the bars appear to stop. The stroboscopic method of measurement is extremely precise.
The degree of control (approximately 3% above and below nominal speed) also enables a user with the faculty of 'absolute pitch' to set record speed to his complete satisfaction, since a total variation of almost a semi-tone is provided.
GENERAL ADVICE
- 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 manufacturers recommend. Do not leave records on the turntable for long periods after use.
- 3 Do not switch on unless there is at least one record on the turntable.
- 4 Do not hold or turn the turntable counterclockwise.
- 5 Always allow the unit to switch itself off, or switch it off manually by one of the operating controls. If the power supply is disconnected during play, the rubber intermediate wheel will remain under pressure and may be deformed after a length of time in this condition.
6 If the cartridge has more than one stylus, make sure that the correct one is presented for the record to be played.

Routine maintenance
LUBRICATION
The bearings of the intermediate wheel, motor and turntable are of oil-retaining material and rarely require lubrication. However, when the need is apparent, remove the turntable and apply a light oil, of the type used on sewing machines, to the points mentioned below.
TO REMOVE THE TURNTABLE
Pull out the record spindle, carefully lever up the inside edge of the rubber mat and prise out the plastic centre disc with a small screwdriver. With the same tool, pull off the wire retaining clip (noting its position for reassembly) and lift off the turntable by applying equal pressure on opposite sides.
Caution: Do not switch on when the turntable has been removed and the speed control is set
When refitting the turntable, turn it clockwise for one revolution as soon as it is on the spindle in order to ease the rubber intermediate wheel back into its proper place.
TURNTABLE BEARING
Apply a thin smear of oil to the inside surface of the turntable bearing. Oil must not come into contact with the driving rim.
TURNTABLE SPINDLE BEARINGS

Adjustments
ADJUSTMENTS
All adjustments are set during manufacture, except stylus force, and should only need to be reset in exceptional circumstances.
Setting checks will be simplified if the power supply is switched off, the automatic operating control is moved fully to START and the turntable rotated clockwise by hand so that the pickup moves slowly and can be stopped in a convenient position for measurement.
PICKUP ARM LOWERING POSITION (For automatic play)
A minor adjustment may be necessary to make certain that the stylus tip lands inside the raised rim of the groove guard to be found on many records. While the arm is on its rest, use a small screwdriver to turn the adjusting screw A clockwise to move the lowering position inward and counterclockwise to move it outward.
PICKUP ARM LIFTING HEIGHT
When the pickup returns to its rest after rising at the end of a record, the top of the finger lift should be 113/1 (46mm) above the top face of a record on the turntable.
Turn the adjusting screw B (diagram 21) clockwise to increase and counterclockwise to reduce lifting height.
PICKUP ARM LIFTING HEIGHT RESTRICTION
The restrictor should prevent the pickup from rising more than 1/2 in (1.5mm) higher than the setting referred to in the previous paragraph.
Use a small screwdriver to turn the adjusting screw C (diagram 22) clockwise to increase and counterclockwise to restrict movement.

- Remove nut fixing the clear plastic cover from voltage changeover block on underside of unit.
- 2 Check that both wire links are firmly pressed onto the correct studs for the power supply voltage. See diagram 23.
- 3 Attach a length of 3-wire flex from a 3-pin power supply plug, or from a power outlet and earth connection on the amplifier, in the following way
- (a) Brown wire to terminal screw L (live) on the changeover block.
- (b) Blue wire to terminal screw N (neutral) on the block.
- (c) Green/yellow wire between washers on earth terminal screw on unit plate.
Always make sure that the power supply is switched off or disconnected when making wiring connections.
CONNECTING THE CARTRIDGE TO AN AMPLIFIER
If phono leads are to be used, follow the connecting instructions on page 5.
Alternatively, either single- or twin-core screened pickup lead(s) can be soldered to the same 4 tags on the back of the phono socket as the leads from the pickup arm. The leads are colour-coded thus
- Red Right-hand channel
- Green Right-hand channel 'earthy'
- White Left-hand channel
- Blue Left-hand channel 'earthy' connection
Connect the lead(s) to the input sockets of the amplifier as instructed by its manufacturer.
For a mono cartridge use the right-hand channel connections only.
For a stereo cartridge used with a mono amplifier, solder one short-circuiting wire link between the same tags on the phono socket as the red and white leads and another between the same tags as the green and blue leads from the pickup arm. This will parallel both channels, either of which should be connected to the amplifier input socket.

For a stereo cartridge used with a mono amplifier, solder one short-circuiting wire link between the same tags on the phono socket as the red and white leads and another between the same tags as the green and blue leads from the pickup arm. This will parallel both channels, either of which should be connected to the amplifier input socket.

FITTING A NEW MOTOR PULLEY
The motor pulley fits closely on the motor spindle to maintain perfectly true running. If the pulley cannot be lifted off without undue difficulty after both fixing screws have been slackened, insert a 4 B.A. screw in the top of the pulley to act as an extractor and turn it with a screwdriver, while holding the pulley stationary, until it is driven off the spindle. A suitable extractor is provided with the new pulley.
The new pulley should be fitted using moderate pressure to make certain that it is pressed onto the motor spindle as far as it will go. If difficulty is experienced due to the close fit, apply a gentle heat to the base of the pulley for a short time with a clean soldering iron, in order to expand the pulley sufficiently to facilitate fitting.
Note that, if a new pulley has to be fitted as a result of a change of power supply frequency then a stroboscopic turntable ring for the new frequency must be fitted at the same time.
Take great care in handling the new stroboscopic ring so that it does not bend. As it is held in position by impact adhesive (exposed when protective backing removed) make sure that the new ring is aligned exactly over the old one before pressing it permanently into position.
