Further Tonearm Adjustments
The vertical tracking angle (VTA) can be adjusted by
raising or lowering the entire tonearm. Loosen the
lock nut on the underside of the turntable with a 22-mm
jaw spanner; then turn the adjustment ring above the
base to raise or lower the tonearm as required.
➔ Fig. 15
If the VTA is changed, the tonearm lift will need to be
to be readjusted. Loosen the locking screw on the to-
nearm lift with a 1.5-mm hex key and carefully raise or
lower the entire lift.

The tonearm tube should be parallel to the platter
surface. Small adjustments of the VTA or the tonearm
lift height can have a large effect. After making any
changes, you should therefore always check whether
there is enough clearance (at least 1 mm) between
the cartridge and the record (when the lift is engaged)
and between the tonearm lift pad and the tonearm
tube (when the lift is disengaged).
