Of course the use of a test record and osciloscope is mandatory for optimal azimuth.
VTA changes and even changes in the height of the armbase, will not change azimuth,
due to precision in construction.
8. Adjustment of the cueing device
The cueing device has no damping for motion as is usual. Due to the construction it is
not needed. It can stay in any position and can be precisely cued on the record. Using
the allen key 1.5mm to release the small knob, which holds the lever and rotating it,
we can adjust the height of the cartridge above the record.
Cueing device level resistance:
Theblocking plate, at the end of air bearing shaft, controls ease of movement of cueing
device lever. If released with Allen key 4mm, it can be pushed away from the main
tone arm tower and this eases movement. When fixing blocking plate back, be sure
that it is parallel to the main tower, otherwise this can cause the distance from
diamond tip to record surface to be different at outer grooves compared to the inner
grooves. Slight rotation of the blocking plate can correct this.
9.
Operation of the tonearm
The compressor should be permanently switched on. When not in use the valve on the
tonearm should be in the lock position. In use, open the valve and move the tonearm
once or twice along the main bearing shaft (if tonearm has not been used for more
then 24 hours). This will clean the shaft of dust particles.
After use merely close the valve on the tonearm. The compressor will go on stand by.
Every few hours or so air release noises can be heard and the compressor will switch
on few times per day when resting in the stand by position.
10. Damping ( optional )
A damping system, consisting of a paddle, damping trough and silicone oil, can be
retrofitted on all Air Line tonearms.
The paddle is fixed on to the threaded rod and the trough is fixed on to the blocking
plate. With oil levels, paddle height, damping can be changed from zero to max. This
is suitable for cartridges with high compliance.
Note: Do not use the damping facility while levelling the tone arm!
Inserting silicone oil
Cut off the tip of the nozzle from PVC bottle. Squeeze silicone
oil into the trough- it will go slowly before it spreads evenly. Fill it up to the line or
about half way up.
