Move the small upper counterweight for more precise balance, by rotating. The tonearm's centre of
gravity is chosen to be around the height of vertical rotation. Therefore balancing the tonearm to zero
is very difficult. Adjust it to be roughly balanced and increase tracking force with smaller
counterweight.
If this is too loose, hold the front part of the counterweight and rotate the rear part until there is a
tighter fit, or lock it into position on the threaded carrier. Opposite rotation will make the smaller
counterweight looser. (Fig. 2)
4. Adjustment of tracking force
Balance the tonearm with the tracking scale, which must be at record height. Rotate the smaller
counterweight towards the tube. Rotation for one turn (observe red dots) will change tracking force
for approximately 0.1g. If you are unable to obtain the correct tracking force, add or remove main
counterweights. By rotating two counterweights along the thread you can obtain the desired balance.
Then simply rotate them one against other and this will fix them. (Fig.1)
Check that the cueing device is at the correct height (see paragraph 10).
5. Adjustment of tangential geometry
Put a record on the platter and adjust VTA in such a way, that the central axis of the tube will be
parallel to the record. This is only a starting point for VTA.
Using the protractor, adjust geometry at two null points. Rough guidance is by the edges of the
cartridge body, but accurate adjustment is by observing whether the cantilever and lines are parallel at
the two null (zero) points.
See appendix 1.
6. Adjustment of VTA
It is extremely easy to set up VTA on this tonearm. Just unlock the lever at the back and rotate the
VTA knob. VTA knob rotation CW- VTA down (Fig.1)
VTA adjustment between any two lines is 0.1 mm (the whole rotation is then 0.8 mm) which allows
for very fine repeatable adjustment. The rigidity of the assembly is such that even in the unlocked
position you will not feel slack. Move the tonearm VTA to the desired height. Simply lock the lever
back with gentle force. Observe the 1 mm scale at the left hand side of tonearm tower. If you run out
of range (10 mm), then you must reposition the tonearm height in the armbase. However take into
account what is the optimal VTA by listening.
Once you find out the correct VTA, rotate outer ring of the VTA main knob and position it into null
position. This is now your starting point for very fine tuning.
