INSTALLING
THE
ARM
REST
The
arm
rest
is
required
to
pro-
vide
proper
arm
support
when
the
tonearm
is
not
in
use.
The
arm
rest
is
positioned
on
the
turntable
deck
so
that
the
tonearm
tube
(M)
rests
within
the
clip
located
at
the
top
of
the
arm
rest.
To
prevent
stylus
or
cartridge
damage,
the
tonearm
should
never
be
left
out
of
the
arm
rest
when
not
in
use.
The
Stereotables
B-12,
B-12H,
B-12GH,
N-33H,
and
N34-H,
have
a
predrilled
armrest
hole
properly
positioned
on
the
deck.
1- Remove arm rest assembly
from
the
packing
container.
Insert
Allen
Wrench
(1)
into
Allen
Screw
(C)
on
the
base
of
the
arm
rest
assembly.
Loosen
the
Allen
Set
Screw.
3- Grasp the clip at the top of the
arm
rest
assembly
and
gently
pull
upward.
Sleeve
(A)
will
slide
out
of
the

so
that
the

(#3)
through
base
(D)
and

bottom
of
the
base
allowing
you
to
move

so
that
the

When
proper

positioning
is
accom-
plished,
tighten
screw
(#3)
firmly
mounting
the
arm

base
to
the
deck.
Be
sure
that
in
the
final
tightened
position,
the
Allen

in
the
base
is
facing
the
outside
edge
of
the

5-
Reinsert

(A)
into
the
base
and
tighten
Allen

(C)
lightly.
Final
adjustment
of

height
will
be
made
after
installation
of

arm.
NOTE:
When
the
arm
rest
is
to
be
mounted
on
a
wooden
deck,
the
same
procedure
outlined
in
items
1
through
5
should
be
fol-
lowed,
with
the
only
exception
being
that
the
wood
screw
(#2)
should
be
substituted
for the
machine
screw
(#3).
The
proper
position
of
the
arm
rest,
in
the
absence
of
a
predrilled
hole,
can
be
selected
by
referring
to

booklet.
SECTION Il - MOUNTING TONE
ARM
The model S-220 Micropoise tone-
arm is designed to be mounted di-
rectly to Stereotables B-12, B-12H,
B-12GH, N-133H and N-34H. These
REK-O-KUT turntable decks have

been
predrilled
to
accept
the
tone-
arm
by
following
this
procedure:
1- Remove snap cover located at
top
right
rear
of
turntable
deck
exposing
the
7/8
inch
tonearm
mounting hole.
2- Remove pal nut (I) by unscrew-
ing from the tonearm bushing (H).
(See
Fig.
2.
)
Insert bushing into the hole by
first pushing the plug-in cables
(J)
through
the
hole
oneatatime
and then pushing bushing (H) into
hole. Firmly seat tonearm base
(F) so that it is flush with the
turntable deck. The tonearm
base should be positioned so
that Allen Set Screw, item (G),
faces the outer edge of the deck.
Slide pal nut (I) over the plug-in
cables.
Passing
the
plug-in
cables through the pal nut one
ata time, thread the pal nut on
to
bushing
(H)
and
tighten
secure-
ly against bottom of the deck. This
nut is not attached until the
tonearm base is revolved in a
position so that the stop in the
base does not allow the tonearm
to swing beyond the center of
the turntable.

SECTION IV - INSTALLING CART-
RIDGE SHELL
The cartridge shell (K)_ has been
removed from tonearm at the fac-
tory, for packaging. (Fig. 1.) The
cartridge shell has been designed
to accept practically every cart-
ridge produced. Most cartridges
are supplied with mounting screws.
In addition, REK-O-KUT designers

Os
have provided two separate sets of
cartridge mounting screws in the
parts package which are capable of
accommodating every type of cart-
ridge in the shell (items 4 and 5).
For deep bodied cartridges use
item 5 which is the longer of the
two sets of brass mounting screws.
For shallow-body cartridges, use
item 4.
INSTALLING THE STEREO
CARTRIDGE
The coding of the terminal pins on
the various cartridges has not as
yet been standardized by the indus-
try. It is therefore necessary to
follow the instructions provided by
the manufacturer of the cartridge
regarding which terminal pin should
be connected for proper cartridge
operation.
The REK-O-KUT color coding of
the connecting wires are as fol-
lows:
White and Black - Left channel
- - Black phono cable (Q, Fig. 2)
Blue and Brown - Right channel
- - Red phono cable (R, Fig. 2)
Blue and White wires are the
"thot'' leads.
Fig. 3 - A - B - C show the typical
connection of a three terminal
stereo cartridge, a four terminal
stereo cartridge,and a monophonic
cartridge. The actual connecting
terminals on the cartridge should
be selected by referring to the in-
structions provided by the car-
tridge manufacturer.

curely engaged.

In
these
cases,
it
is
necessary
to
obtain

MONOPHONIC CONNECTION
'TTONEARM WIRES TO AMPLIFIER
The Micropoise tonearm has been
designed to facilitate the electrical
connection of the tonearm to the
amplifier in the simplest manner.
Connecting cable (J) contains two
completely shielded connecting
wires and one ground wire. The
cartridge connecting cables are
prewired to a standard phono plug
(R and Q) facilitating the direct
connection of the cables to the am-
plifier without the need for solder-
ing. The ground wire is equipped
with a spade lug for installation
under any grounding screw of the
preamplifier chassis. (See Fig. 5.)

STEREO CONNECTION
Each of the stereo channels in the
cartridge is connected through the
tonearm wiring to a separate cable.
Each cable is color coded for
proper connection to the stereo in-
put jacks on the amplifier. The red
cable is connected into the right
stereo amplifier input, andthe black
cable is connected into the left stereo
amplifier input.
When the Micropoise tonearm is
used with a monophonic cartridge,
connect only one pair to the ter-
minals on the cartridge. (See Fig.
3c). It is therefore necessary to
plug only one cable into the ampli-
fier. The other cable should be

shortened by placing a loop in the
cable. (See Fig. 6). This cable
should be left floating free with
extreme care taken to prevent the
unused plug from touching any part
of the turntable deck or amplifier.
SECTION VII - ADJUSTING TONE-
ARM HEIGHT
With the cartridge installed and the
shell assembled to the tonearm, we
are now ready to adjust for the
proper height of the tonearm. For
good sound reproduction and proper
tracking it is essential that the
tonearm be parallel to the record
surface.
1- Place a record on the turntable
(See Fig. 2).
2- For proper tracking results, the
tonearm tube (M) must be paral-
Os

lel with the surface of the rec-
ord. Place the tonearm so that
the cartridge stylus is resting
in a groove on the record.
3- To adjust tonearm height for
parallel operation, loosen Allen
Screw (G) which is located in
the arm base (F).
4- Grasp the gimbal and lift the
entire tonearm until the tone-
arm is parallel with the turn-
table. Use a ruler to check the
accuracy of the spacing between
the tonearm and the turntable at
least two places.
5- After proper adjustment, tighten
the Allen Screw (G) being sure
that the arm height does not
change during tightening. Finger
tightness is sufficient.
The arm rest sleeve should be
firmly adjusted in a similar
manner to hold the tonearm
tube at the proper height.

SECTION VII - ADJUSTING THE
STYLUS PRESSURE
For proper record wear, stylus life
and sound reproduction, the amount
of weight placed by the stylus on
the record is important. Since the
amount of weight is a function of
7 the cartridge used, the pressure on
the stylus must be individually ad-
justed after cartridge installation.
The Micropoise arm takes the
guess-work out of stylus pressure
adjustment with the easily adjust-
able counterweight (P) and the new
Micropoise Balance Control (0),
with reference line centered through

the knob's letter ''0'"' in REK-O-
KUT.
1- Rotate the tracking balance con-
trol kmob (OQ) fully counter-
clockwise before adjusting the
counterweight (P).
2- Rotate the counterweight either
forward
or
backward
until
the
arm
floats
just
above
the

surface. A movement of the
counterweight

NOTE:
In the event proper balance can
not be achieved by movement of

in
the
