Korf Audio TA-SF9
Setting up your Korf tonearm
Cartridge Alignment
Please use the included clip-on gauge to set
the cartridge position in the headshell. Clip the
gauge to the armtube from below, and slide
towards the headshell until firmly adjoined.
Third party protractors may give an incorrect
alignment; when in doubt please refer to the
gauge.
Downforce
The vertical tracking force (downforce) is adjusted by rotating the counterweight. ¼ of a
turn corresponds to 0.5 gram change in downforce (when the additional counterweight
is not installed). If the mass of the cartridge exceeds 15 grams, please use an optional
additional counterweight.
Unlike conventional tonearms, the Korf tonearm can not be balanced in the “zero
downforce” position. This is by design. The center of gravity of the moving part of the
tonearm is above the pivot point, and even the slightest movement of the air registers
with the zero friction horizontal bearing. Thus, the vertical tracking force must be set with
a quality specialized downforce scale (not included with the tonearm).
Antiskating
To set antiskating (bias), start with rotating the antiskating wheel to show approximately
the same number as the set downforce. “Min“ on the wheel stands for “minimum” and
marks a zero position.
Refer to our website for more in-depth instructions.
Tonearm Height
Use the included 3 mm hex key to adjust tonearm height. Loosen the clamp bolt(s) on
the mounting base and then rotate the VTA thumbwheel to raise or lower the tonearm.
Then tighten the clamp bolt(s) back.
