CARRY OUT A VISUAL CHECK on the position of
the yoke as you turn the adjuster screw, to see when it
starts lifting the yoke - never just keep turning the screw
more than 2 turns at this stage once you have seen the
yoke lift off the turret plate.
Th e second way of adjusting to ground datum AND
checking that it is correct is to insert a peice of thin paper
between the underside protrusion and the turret plate.
Adjust the screw anticlockwise very slightly so that when
the paper is inserted between the protrusion and the
turret plate it is held there while you press down on the
turret with your thumb. Keep the pressure on with your
thumb and at the same time very gently pull on the paper
to give it a bit of tension. Now turn the adjuster screw
clockwise to raise the yoke - the point at which the paper
becomes free is the “ground datum position”.
Do the same for the other adjuster screw and use your
“paper feeler gauge” to check that both sides are the same
(i.e both protrusions sit just just clear of the turret plate by just just
the thickness of a paper sheet).
Once both adjuster screws are at the ground datum
simply wind them both in exactly 3 turns each in a
clockwise direction.
A fi nal check is to confi rm that you can just insert the
cork strip marked “gauge” into the gaps as shown on
photo 4 & photo 5. Th e cork strip is 1.5mm thick.
Note: there are minor protrusions from underside of the
yoke - the cork strip should be between the protrusion
and the turret plate when measuring the 1.5mm gap.
WARNING - do not wind to a point where you meet
resistance. If the points are wound in too far (clockwise)
they are forced hard against the jewelled cup and can
easliy splinter the hardened points or fracture the
sapphire jewelled cups.
CHECK THAT ALL IS WELL - Th e stylus down force should be consistently accurate
to within plus or minus 0.05 grams. Higher deviations indicate that the bearing has been
damaged or incorrectly adjusted.
To check consistency, measure the stylus down force over a succession of 10 or so movements
of the arm into the arm clip and then onto a stylus force gauge. It is best to use a digital force
gauge for this as a “balance” type can give inconsistent readings with errors of up to 0.5 grams
