The weight is placed in the notch nearest the end of the
lever for a tracking force of 2.5 grams. The next three
notches inward correspond to 2.0, 1.5, and 1.0 grams,
respectively. (See Figure 3-2-4.)
Place the arm in the arm rest.
6. STYLUS TRACKING ANGLE
After setting up the arm for playing, it is important to
check the tracking angle, because improper tracking angle
will cause distortion and premature record wear. Most
phono cartridges are designed so that when the cartridge is
mounted on a surface parallel with the record surface, the
stylus will track at the proper angle (see Figure 3-2-5). The
surface inside of the cartridge shell (against which the
cartridge is mounted) is parallel to the record surface when
the tone arm is level. Visually check the angle of the tone
arm in actual playing position. If it is not level and parallel
with the record surface, then it is necessary to change the
height of the tone arm’s pivot.
NOTE: Some cartridges are built so that their bodies are at
an angle with respect to their own mounting tabs.
No attempt should be made to change this angle.
Simply make sure that the cartridge mounting tab
surfaces are parallel to the tone arm shell mount-
ing surface before proceeding with the arm height
adjustment.
Figure 3-2-6. Pivot Height Adjustment
To adjust the height of the pivot, loosen the two set screws
near the base of the pivot mechanism and a third screw that
tightens the clamp around the shaft for the arm lifter (see
Figure 3-2-6). When the screws are loose, the entire pivot
mechanism can be slid up and down.
1f the arm cannot be made level in the adjustment range
provided, appropriate spacers which were supplied with the
cartridge must be inserted between the cartridge and the
shell. This, of course, necessitates temporarily removing the
cartridge from the shell and rechecking the arm balance and
adjustment.
If the height of the arm is modified, it is necessary to check
and adjust the height of the arm lifter.
The height of the arm lifter is adjustable by means of a set
screw on its vertical shaft. The crescent-shaped lifting
platform which contacts the arm should be positioned so it
doesn’t interfere with the arm while the record is playing,
yet lifts it fully when the CUE-UP button is pressed.
3-3. DUST COVER HINGE ADJUSTMENT
The hinges of the dust cover on the Marantz Model 6300
Turntable are equipped with spring tention adjustment
screws. Normally, the springs provide sufficient tension and
proper damping for the dust cover, so that it will remain
fully open when lifted, yet descend gently when pushed
down. If desired, the spring tension may be increased to
hold the dust cover open at any position.
To increase the tension of the springs, turn the Tention
