the playing position. Adjust the arm height until there is approximately 3mm (1/8”)
clearance between the underside of the tone-arm and the surface of the record at its
circumference.
3. In standard operation the mounting surface of the cartridge, underside of the headshell
and the centreline of the tone-arm should all be approximately parallel with the surface
of the record. The alignment protractor has been printed to act also as a height guide in
conjunction with the lines on the side of the tone-arm. Measure the distance from the
surface of the record to the upper of the two lines at the front of the tone-arm using the
left-hand scale.
4. Reposition the protractor about 6mm (1/4”) from the edge of the record. Using the right
hand scale repeat the measurement and compare it with the first one. Adjust the VTA
screw until similar reading are obtained indicating that the arm is level with the surface
of the record.
Other dispositions can of course be accommodated and if the readings are noted can be
quickly implemented for special needs. Do not remove the VTA screw at this point.
19. Horizontal Tracking Angle (HTA) Adjustment
1. With the record still on the turntable, place the alignment protractor onto the record
spindle. Move the arm base as far forward as it will go on the turntable sub-chassis.
Check that the anti-skate control is at zero and the VTF is set for suit the cartridge in use.
The stylus position on the protractor is marked with a small cross. Move the arm out of
the armrest and place it so that the cartridge stylus enters the indent formed at the
intersection of the cross-lines, taking utmost care not to touch or knock the tone-arm
once it is engaged.
2. Carefully move the arm base backwards a little at a time until, when directly viewed
from above, the outline of the tone-arm coincides with the arm profile lines printed on
the protractor.
3. Most cartridges have a stylus - fixing-hole centre distance of 9,5mm (3/8”). Correctly
adjusted with these, the outlines of the tone-arm and protractor will coincide when
viewed directly above the centre-line of the tone-arm. With others, according to the
position of the stylus, it will be necessary to view slightly to the left or right of the centre
line; the only requirement for correct HTA being that the outlines appear to coincide
along their length. Replace the arm in the armrest, without disturbing settings, and
remove the protractor.
