Operating The Strobe - Origin live Calypso MK3 Manual

To set correct belt tension finally, lift the belt off the
pulley and let it lose it's tension almost completely
whilst still holding it gently - With no tension
whatsoever in the belt it should be approx 7mm off the
nearside of the motor pulley (flange edge) as per
diagram below. Move the pod till the pulley is this
distance from the belt, then stretch the belt to fit over the
pulley.
Rotate the platter by hand for a couple of turns and
check that the belt still sits between the 2 flanges of the
pulley. If this is not the case and it has ridden up onto a
flange push the belt back onto the crown (Curved portion
between the flanges) and turn the platter. Check the belt
remains on the crown.
People comment that the plastic pulley looks cheap -
However it's made from a special plastic which sounds
better than metal and is notably more expensive to
machine.
Controlling the motor & speed
Note that belt grip varies according to the way it's fitted.
This means the deck will run at a slightly different speed
if you refit the belt inside out or upside down from
previously. Therefore when removing and refitting the
belt take care to replace it with the same side in contact
with the running surfaces.
You will need to set the motor speed yourself. In the first
24 hours of continuous running the motor, the speed
tends to drift but then settles down permanently. You can
listen to the deck from the outset but remember to reset
the speed after the 24 hour run in period and then check
again after a week or so.
Initially motors may be a little noisy but soon settle
down within a couple of days continuous running. Do
not run at over 78rpm as this can harm the brushes over
prolonged periods.
It should not be necessary but you can fine tune the
motor mount to give minimum noise by adjusting the
tightness of the 3 screws next to the motor pulleyfor
minimal tension - "just nipped" on the small rubber O
ring. Always check that the motor pulley is
approximately vertical and that the belt runs clear above
the bottom flange as per earlier diagram.
Motor "running in" should be carried out with platter
turning (no faster than 45rpm).
The motor is "off" when the speed control knob on the
pod is turned fully anti-clockwise and the indent on the
knob aligns to the LED.
Turn the knob one click clockwise to turn the motor on
at 33.3 rpm - The second click clockwise is 45rpm

Operating the strobe

Place the strobe disc on the record to be played. The
strobe rings are labelled on the centre of the disc for
speed and mains frequency.
When setting speed, place the arm on the centre track of
a record, so that the cartridge is tracking the grooves.
This ensures that the drag of the cartridge is taken into
account. Speed variations of up to plus or minus 1% are
quite common on decks and the dc motor is capable of
plus or minus 0.1% accuracy.
