is the measurement from the centre of the spindle to the tip of
the cartridge stylus when the armtube is positioned such that it’s
centre line is directly over the centre of the spindle. Whenever
you rotate the cartridge to align it, the overhang position must
be maintained and checked at the end of the whole procedure.
Follow the manufacturer’s literature and the dictates of your
alignment gauge - different gauges use slightly different methods.
Square up the hi-fi cartridge body with the gauge’s markings, be
sure that the cartridge sides are square or your alignment will be
wrong. When all adjustments are correct, carefully tighten down
the hi-fi cartridge mounting screws. Keeping a fi rm grip on hi-
fi cartridge and headshell together so nothing shifts, delicately
tighten each screw down a turn or so, then repeat until tight.
Tightening down one screw all the way before tightening the
others is almost certain to twist the cartridge out of alignment.
However careful you’ve been, always check the alignment again
after tightening.
Ensure the headshell wires are bent so that they are clear of the
record surface.
VTA Adjustment
To allow the cartridge needle to track at the correct VTA (vertical
tracking angle) it is important that the base of the arm is the
correct height in relation to the platter.
The top or bottom edge of the tube should be roughly parallel
with the surface of a FLAT record. You can use the template card
supplied to help judge this.
It is always best to experiment with vta height by varying it and
listening to the results till you have found the optimum position.
This is necessary because of manufacturing variations in stylus
angle tolerances.

vta wheel to work – see diagram for “vta clamping grub screw”
