REMEMBER STEPS:
a) Put stylus at zero point A and by rotation align cantilever along XY line.
b) Align cantilever along XY line at zero point B by rotating protractor and see where
stylus is on the line XY- in front or behind zero point B.
c) Move cartridge along (not rotating it) for the same distance as stylus is overhanging
zero point B for the same distance to increase the overhang.
d) Repeating these steps (a,b,c,a,b,c,…) will ensure that stylus& cantilever are in
alignment at both zero points A&B.
NOTE: Ensure that cantilever is not twisted due to bias force.
Appendix 2
Fine Azimuth Adjustment
This can be done using an oscilloscope and a test record or by using good records in a
good system and listening to the sound.
Cartridges with fine profiles (VDH,
Microline etc.) are more sensitive to this adjustment. On the other hand cheaper
cartridges are not made so well, making fine adjustment more useful.
With an oscilloscope we measure the differences in crosstalk between both channels.
The idea is that on both channels this is equally small. For that we need a test record
with tracks recorded for left and right channels separately.
Then we compare
crosstalk from the left channel on the right channel- which is a very small signal, to
the same type of signal from the other channel. By adjusting azimuth, crosstalk on
both channels should be made equal.
