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 tonearm
lift with a 1.5-mm hex key and carefully raise or
lower the entire lift. ➔ Fig. 16
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).
