Your motor pod should be installed and the belt fitted for two reasons:
The motor / belt assembly helps to keep the platter from spinning when you
are setting the overhang with your protractor.
To get a feel for installing the belt before you have the cartridge mounted -
especially if your cartridge doesn't have a stylus guard. After you've installed
a belt once, you'll be comfortable doing it with a cartridge installed.
Locate the cartridge screws in the center of the headshell mounting slots.
For the "average" cartridge where the stylus is 10mm forward of the mounting
bolts, this will position the stylus 250 mm from the bearing pivot - the tonearm's
nominal effective length. Make minor fore and aft adjustments as necessary.
Set the tracking force to the middle of the range recommended by the
manufacturer. Adjust the VTA so that the arm wand is approximately parallel to
the platter. Reference our inventory of sample installations, in the
photos
documented at the bottom of this Triplanar Mounting Page
. Verify once more that
the tracking force is still the expected value.
At this point, you have the option of adjusting the overhang in two ways:
Method-1: the conventional manner
- performing all adjustments at the cartridge screws. In this case, lock down the
armboard pivot bolt and verify that the pivot to spindle distance has not changed
from 233.5 mm
Method-2: rotating the pivoting armboard
.
If you use this method, practice gaining sensitivity of rotating the armboard in fine
increments as noted above in the armboard mounting section. You should feel
comfortable in reliably and smoothly rotating the armboard to effect overhang
changes of ½ to 1 mm.
Tighten the cartridge screws and adjust the overhang by rotating the armboard in
small increments (either clockwise or counterclockwise) in order to achieve
correct alignment as measured with your protractor.
Note:
if you use this method, always return the tonearm to the arm rest and lock
the tonearm in place before rotating the armboard.
If you are at all uncomfortable with this technique, then adjust the
overhang in the conventional manner.
