You can see the strobe effect best in fluorescent light,
although an ordinary bulb held about 2 feet from the
strobe disc will also work fine. The bulb flickers at 50
Hz in the EEC and 60 Hz in the USA.
You can purchase bayonet fitting fluorescent or halogen
bulbs to fit normal lamps. Try to shut out daylight when
carrying out speed setting. Also be aware that energy
saving lighting with switch mode high frequency power
supplies or certain energy saving bulbs will not work
with the strobe disc.
As you play the record. watch the relevant ring on the
strobe disc. Adjust the speed as described in next sub-
heading until marks on the ring concerned appear
stationary. It sometimes helps to stare the strobe but
focus your eyes on infinity.
There are other strobes which are easier to read such as
the KAB strobe which can be found on our web site
under vinyl measurement accessories.
There is also a phone app that you can download for
Android or IOS. You simply then place the phone on the
platter and it reads the speed.
Adjust the 33rpm speed
Set the switch on the pod to the first click i.e. 33 rpm
setting.
Fine adjust the motor speed by inserting a small
screwdriver into the hole indicated on the Motor pod
illustration. This is not easy but you need to locate the
screwdriver blade in the slot of the speed adjuster screw.
It helps to look into the hole to see the "slot" orientation
before inserting the screwdriver.
To increase speed, rotate the screw clockwise a small
fraction of a turn. To decrease speed, rotate in the
opposite direction.
Full speed adjustment takes place over 18 turns of the
trimmer screw but you normally need never adjust by
more than half a turn.
If the screw reaches the end of it's travel you can usually
hear a faint clicking. You will not damage the speed
trimmer by over turning, as slippage occurs. Neither will
the trimmer screw fall out. The trimmer screws are
adjusted at factory to give approximately the right speed,
so you need only fine adjust.
Click the speed control knob to the 2nd click clockwise.
Now set 45rpm speed (or 78 rpm if you wish) by
inserting the screwdriver in the 2
motor pod diagram and use the same procedure as for
33rpm.

Notes on Belt & Motor running
Check that the belt rides clear of the flanges – nearly
touching is OK but if the belt sinks down to touch the
flange you need to either increase belt tension slightly or
adjust the tilt of the motor by turning the small crosshead
motor mounting screw positioned nearest the platter.
DC motors are often slightly noisy initially and never
completely silent in comparison to a/c motors. This may
be due in part to the high conductivity precious metal
brushes. These produce much lower levels of vibration
and hence better performance.
Like most turntable manufacturers we recommend you
leave the turntable running between changing records as
this reduces belt wear due to constant stopping and
starting.
The motor and main bearing can take at least 4 days to
fully run in and sound it's best. For this reason it is best
to do a final speed check at the end of this period.
Set final speed only in following conditions
Motor pod is in it's final position.
•
Room temperature is normal and has been so
•
for 2 hours or more.
Transformer and motor pod have been plugged
•
in for over 1 hour as the circuit takes a while to
warm up.
If you move the pod, you will need to re check the speed
and if necessary correct it, by repositioning the pod till
the speed is correct. Never move the pod beyond the
ideal distances mentioned in "fitting the belt". This is a
quick operation if you just leave the motor and platter
spinning, as you slide the pod to adjust tension.
Remember to always set speed with the cartridge
dragging on a centre track of a record.
If moving the pod does not achieve correct speed then
use the speed adjuster screws.
The speed stability of your deck is excellent once
everything has settled down in a listening session.
Be aware that speed is slightly affected by temperature
variation. However most houses are centrally heated and
maintain temperature without significant variations.
Speed variation due to temperature is due to oil
thickening as the temperature drops. 1 degree centigrade
drop in temperature results in a 0.1% drop in speed ( a 5
degree drop will be 0.5% slow). 0.5% speed drift is
barely noticeable to the average listener so this is not
significant. Rega decks used to run 1% fast all the time
to put things in perspective.
Bearing oil can take 2 hours to reach operating
temperature if the deck is left in a cold room. The air in
