SETTING UP
Transit Clamping-Screws
Remove the two transit screws (labeled) on top of the turn-
table base. These screws are provided to secure the power
transformer during shipment, and must be removed before
use.
Power Supply Voltage-Selector Switch
The turntable is arranged for use with either 110 or 220
volt power (50 or 60 Hz). All units are preset for the area in
which they are to be sold, but if it should become necessary
to change the selection, proceed as follows. Remove the
selector-switch cover plate (two screws) and flip the switch
to its alternate position. Turn the cover plate around and
replace it, so that the indented portion is positioned to
prevent inadvertent operation of the switch.
Installing the Cartridge
Take care to handle the cartridge at all times as a delicate
mechanism, and keep the stylus guard in place as much as
possible throughout the following adjustment proccures,
and in subsequent use.
Push the connectors of the headshell wires into the
cartridge terminals, observing the correct color coding:
White — Left channel (+)
Blue — Left channel (—)
Red — Right channel (+)
Green — Right channel (—)
Set the cartridge is place in the headshell,stowing the
wire loops neatly; and fasten, but do not finally tighten, the
two mounting screws in the elongated holes.
Plug the headshell into the tone arm, pull the locknut
forward with a slight pressure, and tighten it counter-
clockwise (see Fig. 2).
Swing the tone arm over the spindle, and set the stylus
position so that the stylus extends about 15 mm past the
center of the spindle (see Fig. 3). Then tighten the two
mounting screws firmly; do not apply excessive force.

Check
that
the

is
not
twisted
(or
the
equivalent
effect)
in
the
tone
arm,
making
the
stylus
out-of-vertical
on
the
record.

necessary,

by
loosen-
ing
the
two
small
screws
on
the
tone
arm
just
behind
the

turning
the
headshell
suitably,
and
re-
tightening

screws
(see

Tone Arm Counterweight and Bias Weight
Slip
the
counterweight
onto
the
back
of
tone
arm,
with
the
plastic
stylus-pressure
dial
going
on
first.
Rotate
the
weight
counterclockwise
to
pick
up
the
guide
thread,
and
continue
rotating
to
bring
it
to
approximately
the
middle
of
its
movement
range.
Slip the loop of the bias weight thread over the bias
arm, then hang the thread over the guide (see Fig. 5). Use
the first groove of the arm for stylus pressures up to 1
grams, the second groove for pressures up to 3 grams, and
the last (inner) groove for pressures above 3 grams.
Bias Hook
Bias Scale
Bias Weight
Stylus Pressure
Set the armlift lever to the down position, uncover the
stylus, and lift the tone arm out of the armrest, supporting
it on your finger. Rotate the counterweight to the point
where
the
arm
is
perfectly
balanced.
Next,
rotate
the
plastic
dial only (without moving the weight) so that the zero
mark registers on the black line on the tone arm. Then
rotate the weight (and dial together) to give the desired
stylus pressure, as indicated by the gram calibrations on the
dial, One full rotation of the weight equals 4 grams of
stylus pressure.
Note:
The
counterweight
itself
is
constructed
in
two
parts.
In the unlikely
event that the above procedure
does
not effect balance
of the cartridge,
loosen
the set-
screw on the outer section
of the weight,
and move
the outer section
back as required
for balance.
Re-
tighten
the setscrew
after adjustment.
Platter and Mat
Carefully
lower
the
platter
onto
the
spindle,
and
set
the
rubber
mat on top.
Tone Arm Height
Place
a
record
on
the
turntable
and
carefully
set
the
stylus
on
the
record
to
visually
check
that
the
tone
arm
is
hori-
zontal,
or parallel
with the record
surface.
If not, adjust the
tone
arm
height
as
below,
once
again
being
careful
to
pro-
tect the stylus from being bumped.
Loosen the three setscrews (see Fig. 6; one screw is a
finger-tighten type) with a screwdriver, on the base collar of
the tone-arm support. Lift or lower to the height required
for levelling the tone arm, and finger tighten to secure in
place. Finally tighten all three screws, by screwdriver.

OPERATION
Locating and Levelling
Set the turntable on a level surface, near to your power
amplifier. For precise levelling, the shock-mount feet can be
raised or lowered by rotating. Make sure as far as possible
that the unit is located where it will not be subjected to
excessive vibration, or to being bumped.
Connecting Up
Insert the plugs of the stereo cord into the output jacks of
the turntable, and connect the spade terminal of the black
(grounding) wire to the screw terminal. Connect the other
ends of the cord to the input jacks and ground terminal (or
chassis) of your power amplifier. Take care to observe the
color coding of the plugs for left and right channels.
Connect the power cord to the unit, and plug in to a
convenient wall outlet. The turntable is now ready for use.
Operation
Place a record on the turntable. Depress the speed selector
button for the correct speed, and switch on the power,
Adjust the speed precisely by turning the appropriate
speed control knob until the applicable strobe ring on the
edge
of
the
platter
appears
to
come
to
a
stop.
Four
strobo
rings are marked, select the correct one according to record
speed and power supply frequency, by reference to the
designation on the turntable escutcheon plate, below the
neon lamp. If the power frequency is not perfectly stable,
as in some localities adjust for minimum motion of the
strobo ring.
Note:
If
the
ring
drifts
to
the
left,
speed
is
too
fast;
turn
the
speed
control
toward
“S”.
If
the
strobo
ring
drifts
to
the
right,
speed
is
too
low;
proceed
oppositely.
Raise
the
armlift
lever,
lift
the
tone
arm
out
of
the
rest
and
set
it
on
the
armlift
plate
with
the
stylus
over
the
lead-in
section
of
the
record.
Then
put
the
armlift
lever
down;
the
stylus
will
lower
smoothly
onto
the
record.
When the record is finished, or to interrupt play at any
time, raise the armlift lever to lift the stylus clear of the
record,
Return
the
tone
arm
to
the
armrest
and
switch
off
the power.
