Unpacking the Simplex MK II
Carefully remove components as required from the foam packaging.
Take care that none of the fluids contaminate the surfaces of your Simplex MK II turntable.
The Simplex MK II packaging has been designed to protect it from the hazards of shipping. It is advisable to save it for further use.
Important: Never place a Well Tempered Lab turntable in direct sunlight. Not only will it have detrimental effects on your valuable
recordings, it will impair the mechanical integrity and performance of your turntable.
Assembly
For ease of assembly we recommend a flat work surface, such as a table or bench. All necessary tools have been provided.
1. Install bearing cup in plinth adjust to approx. 40mm (1.6in) above plinth and tighten set screw. See Fig (1).
Fig (1)
2. Install tonearm suspension pillar to approx 95mm (3.8in) above plinth and tighten set screw. Complete with tonearm suspension
rod. See Fig (2).

3. Install tonearm rest / lock in plinth approx. 50mm (2in). See Fig (3).
Fig (3)
Note: There is no requirement to apply excessive force to the above set screws. A gentle tighten is sufficient to secure the
components. Over tightening can lead to damaging the plinth.
Suspending the Golf Ball Tonearm
Before embarking on this procedure, we suggest a review of the manual from Fig (4) - (9) is mandatory.
1. Coarse azimuth adjustment if necessary can be achieved by rotating the tonearm within the golf ball. The Head-shell should be
parallel to the small nylon filament points. See Fig (4).

2. With a small amount of care take tonearm and apply one and a half turns of the nylon suspension from the golf ball around the
azimuth adjustment collar. See Fig (5).
Fig (5)
3. Correct bridle length when tonearm is suspended is approximately 25mm from top of tonearm to bottom of suspension rod. See
Fig (6). Apply a complete anti-clockwise twist to the azimuth adjustment collar and install on the suspension rod. The twist on the
nylon suspension effectively applies the correct anti-skate. See Fig (6) - (9). Correct azimuth adjustment is achieved by rotating the
azimuth collar in the directions of the arrows.

4. Adjust pillar, rod and azimuth collar to allow golf ball to float central of bearing cup.
Note: All the above adjustments can be fine tuned when cartridge is installed.

6. Fit tonearm connector to socket making sure that the connector "locks" in place, failure to ensure this connector is firmly locked
may result in a loss of signal on either channel. See Fig (10)

Installing the Platter
Please ensure that the point of the triangle hold in the upper teflon bearing is correctly orientated to the motor pulley. See Fig (11). If
necessary consult your dealer.
Fill the bearing with synthetic oil supplied to a level of approx. 5mm (1/4”) above the bottom Teflon bearing, this is not critical. Do not
overfill. Over-filling the bearing will cause the oil to overflow the bearing housing when the platter spindle is lowered into the bearing
housing. Gently lower platter into bearing. See Fig (12) - (13). It is most important that spindle is located correctly in the centre of
the lower thrust bearing. Failure to locate the pivot point of the spindle correctly will cause the platter to rotate abnormally. The
spindle has been designed to protrude through the platter to provide a central lifting point that enables the user to easily achieve
this.
Important: The unique design of the zero clearance Well Tempered Lab top bearing allows the spindle to be virtually free standing.
It is perfectly normal for the platter to tilt away from the motor when the belt has not been installed.
Should there be any necessity to replace the bearing oil, any synthetic motor oil of any brand within a viscosity range of 5W-50 is
acceptable.
Note: The zero clearance Well Tempered bearing can rotate for hours without oil. If you wish, you can complete other adjustments
before applying the bearing oil. See Fig (12).

Speed Control
Speed change is effected by manual movement of the belt on the pulley. 33.5 RPM on the small diameter step on the pulley, 45
RPM on the larger diameter step on the pulley.
Installing the Belt
Start with the belt around the motor pulley, take care the other end clears the centre spindle and rotate the platter, the belt will track
around the platter. See Fig (14). Well Tempered Lab belts if dropped are easily misplaced, we give you two but suggest you place
the belt on something dark to make it easily seen.
Fig (14)
Belt for Life Policy
The Well Tempered Lab offer a "belt for life policy" just send a self addressed envelope with stamp to your distributor or dealer for
replacement.
Speed adjustment
This is factory set, but if required, this can be achieved by carefully adjusting the small screw adjacent to the DC socket.

Fitting the Cartridge and Golf Ball Tonearm adjustments
1. We recommend fitting the cartridge with the tonearm in position. However it is possible to fit the cartridge before suspending the
tonearm (see Fig 15). Great care needs to be taken when installing the cartridge as the Well Tempered Lab bears no responsibility
for cartridge damage.
Fig (15)
2. Install the cartridge to the manufacturer's specifications. The Simplex MK II features a head shell that requires no tracking
alignment adjustment. We strongly recommend it remains firmly fixed in the correct position as supplied.
3. The Simplex Golf Ball tonearm has an effective length of 9” (228.6 mm). The head-shell is fixed ex-factory in the optimum
position. There is no provision for over-hang adjustment. Some alignment protractors may well disagree. However, The Well
Tempered Lab stands by their convictions.
Important: There is absolutely no reason to torque head-shell/cartridge mounting hardware to excess. Cartridge mounting
hardware only requires firm but gentle tightening. Heavy handed torquing of mounting hardware can result in movement of the
Simplex MK II head-shell (refer to www.welltemperedlab.net on tracking geometry).
4. There is an optional finger lift which can be attached to the cartridge fixing screw, adjacent to the right hand side of the plinth.
5. Apply enough damping fluid so as that no more than one third of the golf ball is submerged in fluid. See Fig (16).
Note: Damping can be altered by simply raising or lowering the damping cup, it is not critical and maybe adjusted to suit the
listener's own preference.
6. Set tracking force with stylus gauge, supplied to cartridge manufacturer's specification.
7. To set tracking force, two counterweights are supplied to enable correct tracking force to be applied to cartridges of various
weights. We recommend choice of counterweight (s) that allow correct tracking force to be obtained with weight (s) as close to the
tonearm lead out cable as practicable. This is not critical but care needs to be taken as to not damage tone-arm lead out cable
when attaching counterweights to tone-arm.
8. Adjust tonearm for correct VTA by set screw on suspension pillar.
9. Correct Azimuth can be obtained by gently rotating the azimuth adjustment collar to allow the cartridge to track parallel to the
record surface. This can be achieved whilst the record is rotating and requires only minor correction in both directions to achieve the
correct result.
10. Due to the viscosity of the damping fluid adjustments in both tracking force and azimuth require the tonearm to momentarily
settle to effect the correct results.
