Marantz 6300 - Page 8

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 7.)
Place the arm in the arm rest.
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
8). The surface inside of the cartridge shell
{against which the cartridge is mounted) is paral-
lel 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 necessa-
ry 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 mounting surface before
proceeding with the arm height adjust-
ment.
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 9). When
the screws are loose, the entire pivot mechanism
can be slid up and down.

lf 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 cueing mecha-
nism to operate properly. See “‘Cueing Controls”,
page 9.
