GENERAL
All models of this series Magnavox Record Players
are basically the same. Differences lie only in external
appearance items and, in some cases, t h e type of
drive 1notor.
'Some versions in t h i s series incorporate extended
type control knobs while othe1·s use a short type knob
assembly. The deluxe players covered in this manual
utilize an 11" turntable disc.
The chart on Pages 16 & 17 shows the major differences
in these various models. 0t h e r minor differences
are identified in the exploded view diagrams and re
placement parts lists.
All models are four-speed designed for operation at
16 2/3, 33 1/3, 45 and 78 RPM.
CHANGE CYCLE
The changer utilizes a "Velocity Trip" mechanism and
the change cycle initiates by the fast inward motion of
the pick-up arm when the stylus enters the lead-out
groove at the end of the record.
As the tone arm tracks on the record, the Pick-up
Positioning Finger ''A" in Figure 3, which moves in
unison with the tone arm, pushes against the Striker
Feed Lever (111). The Striker Arm (121) is fed inward
toward the turntable hub by t h e friction of its own
weight resting on the curved end of the Striker Feed
Lever (111).
ISSUED: DECEMBER, 1966
As the record is playing, the Striker Arm (121) moves
slowly toward the hub of the turntable, but the velocity
of the Tone Arin is not sufficient to trip tl1e mechanism;
since the wiping action of the l1ub projection n1oves the
Striker Arin (121) back with each revolution of the turn
table.
However, when the stylus enters the lead-out groove
at the end of the record, tl1e velocity of the Striker
Feed Lever
(111)
is sufficient to cause the Striker Arm
(121)
to move in ahead of the turntable hub projection.
The St1�iker A1·m (121) is then "struck" by the hub pro
jection and pusl1ed far e n o u g h t o cause the Drive
Release Lever (131) to pivot and release the Locking
Pin from the tab on the b o t t o m o f the Main Cam
Gear Assembly (109). The assembly is then unlocked
from the out-of-cycle or "Play'' position, permitting
the
.
Drive
Wheel
(17)
and its associated
gear train
to
be pulled into contact with the motor pulley which drives
the Main Cam Gear Assembly t h r o u gh the change
cycle.
The Main Cam Gear Assembly makes one con1plete
revolution in a clockwise direction during the change
cycle.
As the Main Cam Gear (109)
rotates, the
Cam
Gear
Locating Roller "B" rides on various
elevations
on
the Cam Gear (109), causing the Tone Arm Lift Lever
(118) to pivot and raise the Pick-up Lift Spindle (103).
This action raises the Tone Arm and
determines
its
vertical travel.
