-
Locate the suspension gauge in the documentation envelope. Punch it our of the card. Do
not consider “A” nor 1 & 2.
-
Place the gauge on the acrylic base with the “B” side against the lock nut.
Note 3: With the spring adjusted as per step one, the bottom of the suspension housing should be
well above the “B” step on the gauge. If it falls below, this is an indication that the spring used is
not suited for this tone arm application, it is too weak. With a new spring start the procedure again
from step one.
Note 4: Always start the calibration with the module near the tone arm then move to the rear left
and finally to the front module.
-
Rotate the spring counter-clockwise by increments of ¼ of a turn. Apply a pressure on the
record clamp to stretch the spring prior to taking a new reading.
Note 5: To make this operation easy, one hand should hold the suspension housing to keep it from
turning while the other is rotating the spring. Apply a downward pressure at the same time to
facilitate the rotation.
-
For the first round repeat the operation until the suspension housing is 3 mm (1/8”) above
the “B” step on all three modules. For the second round, reduce the increments to 1/8 of a
turn or less until the housing touches the gauge lightly.
Note 6: In the event that the housing goes below the “B” step, start the procedure from step one
again.
Note 7: Once the proper adjustment is achieved it is important as a final check to verify to the
relative position of the bottom of the spring with its holder. This can be done by simply lifting the
suspension housing just enough so you can see the spring. If you can see the spring anywhere
from almost flush to the spring holder to up to 3 coils out, the spring is in a safe range and the
risk of collapsing is nonexistent. If the spring can not be seen showing below the holder a careful
inspection should be performed on this spring to make sure it is still at less then ½ turn inside the
holder. This is an indication that the spring is approaching the limits. The use of a softer spring
should be considered. Failing to do so could eventually cause the spring to slip out of its holder
thus causing potential damages to your record and your phono cartridge !
