Pressure should then be released by slightly unscrewing the clamp until the outer edge is
touching the mat again. This is the position in which the record is held in firmest contact with
the mat.
With practise there is no need to stop spinning the platter while changing LPs or using the
clamp. The clamp can also be used without washers.
VTA change:
Rotation of the toothed knob at the base of tonearm tower raises and lowers the top part of the
tonearm tower (seen from the top, counterclockwise rotation raises VTA). Adjustments are
in repeatable increments below 0.01mm. The rigid construction allows for this to be done
while records are playing, without changing the azimuth. For more details see the sections
on tonearm tower and VTA clock.
Maintenance:
Mat:
The top surface of the mat can be cleaned using a roller textile cleaner.
Bearing:
Oil in the bearing will last for 3-4 years or more. Running the bearing without oil will do no
harm due to the choice of materials and type of construction.
Oil should be added if the top reservoir (with ruby ball ) is totally dry. The oil level will be
below the ruby ball as the bearing surface increases the level of oil above the ruby ball when
the subplatter is lowered onto the shaft. When the subplatter is removed you can see the level
of oil inside its sliding ring (golden colour). If it is above the sliding ring in the subplatter,
there is plenty of oil. If excess oil is added it will run into the appropriate extra reservoir.
Belt:
Periodically remove the platter and remove the belt. Clean belt and the running surfaces of
the motor pulleys and the subplatter with a soft cloth soaked in alcohol (every 12 months).
For best performance replace belts every 5-7 years.
VTA Gauge:
The sign 'B' in the top left corner of the clock indicates that the battery should be replaced.
Push clock out of brass frame and reach battery cover from the outer side.
Remove the battery cap by turning it counterclockwise with a coin and remove old battery
replacing with a new battery with the + side facing up. Secure the battery cap. Immediately
after the battery has been set, a meaningless display or 'E' will appear. This is quite normal
so merely continue to set up 'origin' again.
