employs
a

Change Cycle
The
changer
employs a "Velocity Trip" mechanism which
initiates
the change cycle when the Tone
Arm
undergoes
increased
inward
acceleration,
This
takes
place
after
the
stylus enters
the
lead-out groove
at the
end
of
the record.
As
the Tone Arm
tracks
the
record,
a post
attached
to the
Vertical
Pivot
Bracket
Assembly
(106)
pushes against the
Striker
Slide
[86-3).
The Striker Slide is.
fed
inward, makes
contact
with the
Striker Friction Plate
(&2-4L
and
moves
the
Striker
(62-3]
toward
the
Turntable
Hub, The
velocity
of the Tone Arm, during normal
tracking,
is. not sufficient
to trip the
mechanism
because the
wiping
action
of the hub
projection moves the Striker back with each revolution of
the turntable.
However,
when
the stylus enters
the
lead-out
groove
at
the
end of the record, the velocity of the Striker Slide is. suff ic-
ient to cause the Striker to move in ahead of the turntable
hub projection. The projection then engages the Striker and
pushes it
far
enough to move the Intermediate Gear
(62-5!
out
of
the
recess
In
the periphery
of
the
Main Cam
Gear
(B4). This meshes, the
Intermediate
Gear
with both the
Turntable
Gear
and the Main Cam Gear and initiates, the
change cycle. Failure of this automatic trip mechanism
may be due to the presence of contaminants on the Striker
and
Striker
Friction
pJate (Refer to Servicing the
Inter^
mediate Gear & Striker Assembly).
As the
Mam
Cam Gear
starts
its
change cycle rotation, h
actuates
the
Muting
Switch
Slider
(3$),
which
in turn causes
the Muting
Switch
Contact
to
ground
the pickup
output.
While
the Main Cam Gear rotates, the roller on the Tone
Arm Lift Lever
(103)
rides on a series of elevations on
the
Main
Cam Gear, which cause the Lift Lever to pivot. This
moves
the Tone
Arm
Life
Rod
(98t
and
controls the vertical
travel nf
ihe
Tone
Arm.
As
the
Main
Cam Gear continues to rotate, the Tone Arm
sizes
the next
record.,
The Cam- Follower
Pin
on the Feed
Lever
(109)
moves laterally with the Tone Arm to one of
three grooves in the Main Cam Gear. The selected groove
determines the Tone Arm set-down position.
As
the
Mairi
Cam Gear
rotates,
the roller located atop the
Record
Dropping Slide
(661
contacts a cam lobe and is
pushed outward, away from the center of the cam.
This
causes lateral movement of the pawl within the Record
Propping
Spindle
(15)
which pushes the bottom record
off
of
the spindle
shelf
and
drops it
onto
the
turntable.
As
the
Record
Dropping Slrde
retracts, the
Pawl
Lift
Spring
pushes
the pawl upward and into position for the following record.
Ar
the end of the change cycle the
Intermediate
Gear drops
into
a
recess
of
the
Main
Cam Gear and
disengages
from
the
Turntable
Gear
As
this
occurs
the
Muting
Switch Contact
opens and the Cam- Follower Pin moves
out
of
the cam
groove and into the "play recess'
F
area of the Main
Cam
Gear.
