2. Check the gap between the muting switch contacts
to be certain that a strip of newspaper or a metal
"feeler'' gauge . 003" thick can be inserted between
the1n (this is minimun1 gap).
3. If there is no gap, or if the gap is insufficient,
the tag end of the Switch Operating Lever (141)
may be slightly bent away f r o m the sub-plate
assembly.
Pickup Tracking Adjustments
Improper pickup tracking may be caused by any one of
the following:
1. Insufficient slack in pickup leads.
Check to be sure that the pickup leads are free
and that sufficient slack i s maintained between
the rear of tone arm and baseplate.
2. Cam Following Pin "C" touching bottom of cam
groove.
Check to see i f the Cam Following Pin "C" is
rubbing bottom of cam groove when in the "playing
recess". This pin is properly positioned when it
touches halfway up ramp "E" (see Figure 4).
This adjustment is m a d e by rotating screw "I''
(Figure 7).
3. Striker Feed Lever
(111)
resting on sub-plate.
Check to see that the Striker Feed Lever (Figure
3) is perfectly free on its pivot "J" and is con
tacting the sub-plate at its forward end (under the
Striker Arm). At the same time the Striker Feed
Lever should be clear of the sub-plate at the rear
end by approximately 1/16''. If this clearance is
insufficient, it may be increased by inserting a
screwdriver between the Striker Feed Lever {Ill)
and sub-plate and exerting a slight upward pres
sure.
4. Chipped or damaged stylus.
If it is suspected the pickup stylus i s worn or
damaged, replacement is to be made with an exact
replacement stylus of the original type (see Pick
up and stylii information on Page
11).
5. Insufficient stylus pressure.
See "Stylus Pressure Adjustment".
Tone Arm Height
The Tone Arm Height Adjustment Screw "K'' (Figure
5) is used to set the h e i g h t to which the tone arm
raises during the change cycle. During the change
cycle the tone arm is lifted up and moved out over the
rest post. During this time the clearance between the
top o f the ton e arm and the underside of the next
record on the shelf should be approxi1nately 1/ 4". To
obtain this setting, rotate screw "K" clockwise to lower
the tone arm or counter-clockwise to raise it.
Record Dropping Adjustment
Rotate the Main Cam Gear (109) by hand until the Record
Push-Off Pawl travels t o its maximum position be
tween the spindle shelf. At this point the Pawl should
protrude just slightly beyond the spindle shelf.
If the Pawl does not protrude beyond the spindle shelf,
loosen the two screws (137) and move the Pawl Adjust
ment Plate (135) until the Pawl does protrude beyond
the shelf. NOTE: The Pawl Adjustment Plate (135)
slides horizontal to, and directly across the Record
Dropping Slide (134).
Stylus Pressure Adjustment
Use a suitable gram scale and following the manu
facturers instructions c he ck t h e stylus pressure.
Stylus pressure is set by rotating screw "
_
L" in Figure
5. Stylus pressure is to be set for 3 grams plus or
minus
1/2
gram.
Idler Wheel Height Adjustment
The Idler Wheel
(22)
s h o u l d be adjusted so that it
contacts the motor pulley in the center of the proper
step, making certain the lower face of the Idler Wheel
does not rub on the flange of the next lower step of the
motor pulley.
An adjustment screw located on the baseplate next to
the Idler Wheel (see Figure
1)
is provided to adjust
the vertical positioning of the Idler Wheel. This screw
should be turned clockwise to raise the Idler Wheel,
counter-clockwise to lower it.
IMPORTANT NOTE: W h e n making t h i s adjustment
always be s u r e the changer is supported fron1 the
baseplate and that the motor is completely suspended.
