OPERATION
MAINTENANCE
• Operational maintenance .... the things you will have to do to keep your
equipment producing brilliant pictures, accompanied by true reproduction of
sound. Many of these suggestions will become a part of routine operation. They
are just as important as correct focus or good tone' if you are to enjoy your
Sound Kodascope.
PROJECTION
SETUP
The Night
• If you are to receive the fullest satisfaction from your
Sound Kodascope, you should project pictures of an ade-
quate size and brilliance. Generally speaking, there are
four things which govern picture size-size of screen,
focal
length
of lens,
brightness
of screen, and
distance from pro-
jecfor to
screen. Whatever the limiting factor may be-
screen size, lens focal length, screen brightness, or pro-
jector-to-screen distance-the graph below will give you
.quickly the information you need to make the correct
projection setup and enjoy maximum-size pictures.

Then turn the speaker opening toward
the audience. The speaker case may be closed or left open.
Place the Kodascope case on a firm table with the front
end flush with the edge. lift the four latches and lower
the two sides of the case.
Several operating positions are possible. The Kodoscope
can be operated from the case as shown below, or
-if additional neightis rrecessaryj'it con be placed upon the
closed case as shown on the opposite page. Slight de-
pressions in the case side indicate the locotion for the
Kodascope feet when it is used in the latter position.
Remove the two
REEL ARMS.
The larger cover-side can
be removed, if desired, by pushing it toward the rear of
the table until it is released from the hinges. The small
side of the case can be ,left extended on the table or it
can be dropped as shown above.
Loosen the two
REEL-ARM SCREWS
and attach the upper
and lower reel arms. Use a coin to tighten the reel-arm
screws. Place the spring belts over the reel-arm pulleys.
Locate the lower spring belt according to reel size.
NOTE: When using a 1200-, 1600-, or 20oo-foot take-up reel (or any
reel with a core diameter of more than 4
Y2
inches), place the lower
spring belt over the larger reel-arm pulley. For smaller reels, use
the small pulley.

Withdraw sufficient speaker cord from the speoker-
case Cordomatic reel to reach the projector. Attach the
speaker-cord plug to the receptacle in the rear of the
projector.
To recail the speaker cord, pullout on the cord until a
clicking sound is heard; then permit the reel to draw the
cord into the case. Do not allow the plug to slap against
the case; hold the plug while °the cord is being recoiled.
The
ON-OFF SWITCH
is the master control switch for
all circuits. With the switch at ON, the threadlight is
lighted and the projector is ready for operation.
Turn the
CONTROL SWITCH
to PROJECTION LAMP. Rotate
the lens until the margins of the lighted area on the screen
are sharp. For lateral adjustment of the lamp' to improve
the uniformity of the brightness, turn the
LAMP CENTERING
SCREW
a trifle either way with a coin or screwdriver.
For vertical adjustment, turn the
ElEVATING WHEEl.
Make
this adjustment provisionally; it may have to be altered
slightly after the framing lever has been set in the proper
position for the film.
Turn the control switch to OFF and turn the EXCITER
LAMP CONTROL knob in a clockwise direction as far as
it will go beyond ON. As soon as the small red window,
next to the fidelity lever, is illuminated by the exciter
lamp, the sound system is ready for operation.
AFTER THREADING,
CHECKVVVV
1
Turn the
THREADING KNOB
counterclockwise a few times
to be sure that the film is properly threaded, that there
is no slack film between the supply reel and the feed
sprocket, that the claws of the pull-down engage with
the film perforations, and that the loop sizes are
maintained.
2
Turn the MOTOR CONTROL knob to SOUND SPEED.

THREADING
11
Place the reel of film on the supply spindle with the
film coming from the bottom of the reel, perforations
toward you. Lock the reel on the spindle with the
latch. Draw off approximately three feet of film.
Insert the film between the feed sprocket and sprocket
clamp, engage the film perforations with the sprocket
teeth, and close the clamp.
Open the gate by pushing forward on the lever
until the gate latches.
Turn the threading knob until the pull-down claws
are withdrawn from the gate.
Form the upper loop. Then slid.e the film behind the
gate and center it between the .edge guides on the
rear plate. Close the gate.
Form a lower loop as illustrated, hold back the
pressure-roller lever and insert the film over the
sound-loop roller. Release the pressure-roller lever.
Press dow on
tb
tension-roller lever and place the
film beneath the sound drum.
Thread the film between the sound sprocket and the.
sprocket clamp. Engage the film perforations with
the sprocket teeth and close the clamp. There must be
no slack between the sound-loop roller and the sound
sprocket.
Thread the film over the stripper stud and beneath
the snubber.
Place the take-up reel on the take-up spindle and
lock the reel on the spindle with the latch. Then insert
the end of the film into a slot in
the core of the take-up reel. Take
up the slack between the sound
sprocket and the take-up' reel.
To place the take-up belt under
proper tension, hold the take-up
reel with the left hand and turn
the knob on the rear of the
spindle in a clockwise direction.
B
A
SOUND
Focusing the beam from the exciter lamp on the sound
track of the film is extremely important and is accomplished
by moving the FIDELITY lever up or down. The position of
the sound track on the film base will vary depending upon
whether you are using (a) l o-rnrn sound-on-film originals,
l o-rnm prints from 35·mm originals, or (b) l o-rnrn duplicates
of l o-mrn originals, block-end-white or Kodachrome.
The sketches illustrate the position of the beam upon the
two tY,f>esof_film: ~ne threaded with emulsion side of film
toward the projector lens (a), and the other with emulsion
side away from the projection lens (b).
Regardless of which type film you are using, focusing is
extremely simple. Turn the TONE control knob clock-
wise as far as it will go; then move the FIDELITY lever
up or down to the position giving the most complete range
of sound. When the bearp is sharply focused on the sound
track, you will obtain brilliant reproduction of music, and
speech will be crisp and distinct. After the fidelity lever
has been set, adjust the TONE and VOLUME controls in
the conventional manner.
REWINDING
At the completion of projection, turn the control switch
to OFF and pull out on the
REWIND LEVER.
Attach the film to the upper reel by inserting the end of
the film into the reel slot. Give the reel a few turns toward
the Kodascope to make sure that the end of the film is
secure. See that the film is not twisted between the two
reels.
Turn the control switch to MOTOR and permit the film to
rewind. Exert a slight retarding pressure on the lower
reel to keep the film from unwinding too rapidly.
After the film is rewound, turn the control switch to OFF
and return the rewind lever to its original position.
TO PROJECT SILENT PICTURES
Thread the film through the feed sprocket, the gate,.
and through the sound sprocket as shown in the illustration
on the next page: Be sure to allow an upper and a lower
loop.
Turn the EXCITER LAMP CONTROL knob to OFF unless
VI
a microphone or. a phonograph pickup is to be used (see
instructions below). Turn the MOTOR CONTROL knob
toward the silent speed arrow. Regulate the speed of
silent pictures with the MOTOR CONTROL knob.
If silent pictures are projected without microphone or
pickup, it 'is not necessary to have the speaker connected.
MICROPHONE OR
PHONOGRAPH PICKUP
To use phonograph music or supply microphone com-
ments with silent pictures, a jack for a high-impedance
microphone or phonograph pickup is provided on the
left side of the Sound Kodascope. It may be necessary
with certain high-level phonograph pickups to use an
auxiliary volume control on the pickup to prevent dis-
tortion in the first stage of the amplifier. Sound from the
film is not cut off when a plug is inserted in the jack, thus
permitting "mixing" of sound from microphone or phono-
graph with sound from film.
Microphone or Phonograph and Silent Pictures:
Turn the
exciter lamp control knob until it clicks at the ON position.
Control volume with the VOLUME control knob. Do not
turn the VOLUME control up so for that the microphone
howls or "feeds back."
Microphone or Phonograph and Sound Pictures:
Regulate
sound from film with the exciter lamp control knob and
microphone or phonograph volume with the VOLUME
control knob.
Oper(Jting Suggestions
No sound will be heard if any of the following conditions exist:
• Speaker and projector not connected by speaker cord. _
• Volume control not turned on.
• Exciter lamp control not turned on. Red window not illuminated.
• Exciter lamp burned out, or not located on all three studs,
• Fuse blown.
• Tubes or photoelectric cell need replacement.
For sound pictures, be sure the exciter lamp control knob is turned beyond ON as far as it
will go and that the motor control knob is at sound speed. For silent pictures, not accompanied
by phonograph or microphone, the speaker need not be connected to the projector, nor the
amplifier turned on.
Pictures will be out of focus if the gate is left open during projection. Loss of loop will cause
unsteadiness in the projected pictures.

CLEANING LENSES AND REFLECTOR
The condensing lenses and the projection lens of the
Sound Kodascope are lumenized, that is, a special hard
coating has been applied to all the air-glass surfaces.
The tinted appearance of the lenses is due to this treat-
ment, which increases the light transmitted, thus increasing
the brilliance of the image on the screen.
like any fine lens, the projection lens on your projector
should be cleaned with care. Remove the lens by drawing
it out of the lens holder. With a soft lintless cloth, or
Kodak lens Cleaning Paper, carefully wipe the two lens
surfaces.
To clean the
CONDENSER lENS,
remove the
LAMPHOUSING
as described on page
III.
Remove the condenser lens from
the housing and clean it in the same manner as the pro-
jection lens. When replacing the condenser lens, push it in
as far as it will go and tighten the lock screw. Clean the
REFLECTOR
without removing it from the lamphousing.
Do not wet the cloth used for cleaning lenses.
If
moisture
is required, breathe on the lenses or use a drop of Kodak
lens Cleaner.
CLEANING THE GATE
To remove small pieces of film emulsion which are visible
on the screen during. projection, remove the lens, reach
throunh
the lens holder with a brush or small stick, and
carefully run the brush or stick around the edges of the
cperture.
To remove particles of emulsion from the surface of the
GATE,
use a strip of soft cloth about the width of the fllrn.
Rotate the threading knob until the pull-down claws are
withdrawn. Dampen the cloth and thread it into the gate
just as film is threaded, close the gate, and draw the cloth
up and down.
CLEANING THE SOUND OPTICS
To clean the sound optics, which must be done occasion-
ally, remove the
KNOB
and
EXCITER LAMP COVER.
Loosen
the
SCREW
holding the
RETAINING SPRING,
move the spring to
the right and draw out the
SOUND OPTICS.
Be careful not
to bend the spring. Wipe' the end of the sound optics
nearest the sound drum with a soft cloth and clean the
opposite end with a soft brush. Clean the end of .the
SOUND PICKUP ROD
with a brush' and remove any dirt from
the
SOUND DRUM.
When replacing the sound optics be
sure that the cam on the FIDELITY lever is between the
rails of the sound optics.
Replace the cover over the exciter lamp.
REPLACING LAMPS
~
I
Threadlight-
To replace the threadlight, first remove
the shield by drawing it toward the front of the Koda-
scope; then unscrew the lamp from the socket. Use a
6-watt, 120-volt, S-6 clear, candelabra screw-base lamp.
Screw the new lamp into the socket; then replace the
shield. Use the locating lug and slot to correctly position
the shield.
Projection
Lamp-Follow the directions on page III to
.replace the projection lamp. After installing a new lamp,
adjust for evenness of illumination by turning the lamp
centering screw. If the lamp has an opaque top, do not
use a lamp cover.
Exciter
Lamp-Loosen the
KNOB
and remove the
EX-
CITER LAMP COVER.
Push forward on the spring-flange
mounting and at the same time twist the exciter lamp
counterclockwise. The lamps have prefocus bases and
can be inserted one way only. Turn the lamp clockwise to
lock it in position.
OILING
There are six points which require occasional lubrication.
They will need oil before the Kodascope is first used and
at regular intervals, depending upon how frequently the
Kodascope is operated.
In ordinary service, the. motor bearings must be oiled
about every five or six months with five or six drops of oil.
Oil the four places indicated on the illustration and the
bearings in the supply and take-up spindles.
All other
bearings are self-lubricating and need
no
oiling.
Use Kodascope oil or an oil of similar body. Do
not
use
light oil.
IX
l~.. ~/
REPLACING FUSE
Failure of the exciter lamp to light may indicate trouble
in the ornplifler system or that the fuse is blown. To replace
the fuse, located on the bottom of the Kodascope, dis-
connect the power cord, unscrew the
FUSE CAP,
and pull
the fuse from the cap. Insert a new fuse (3 amperes,
250 volts, part No. 78464) into the cap and replace the
cap on the machine.
If
the exciter -lamp still fails to light,
the oscillator tube (the second tube from the right-hand
end) may need replacing.
The Sound Kodascope FS-10-N is designed for use with
alternating current only. If the projector is connected to
direct current, the fuse will blow. See page XIV for
servicing helps.
R~PLACING
BELTS
Remove the four
SCREWS
from the forward cover. When
replacing the upper spring belt, push the rewind lever
in
so that the upper pulley will turn freely. Feed the belt
through the opening in the front of the Kodascope and
between the two
BELT GUiDES
and the pulley. To replace
the lower spring belt, pull the rewind lever
out
and pro-
ceed as described above.
To replace the
DRIVE BELT,
the threading knob must be
removed and it is more convenient if the flywheel is also
removed. To remove the threading knob, loosen the two
opposite screws in the hub of the threading knob. Raise
the Kodascope with the elevating screw until the flywheel
clears the extended glider post; then remove the
smaller
nut holding the flywheel. Hold the sound drum while turn-
ing this nut. Place the new belt around the pulleys; then
replace the flywheel and threading knob. Be sure to use
the washer between the flywheel and nut.
When attaching the front cover, replace the short
screw as indicated in the illustration.

SOUND PICKUP ROD.
REMOVING THE AMPLIFIER
Remove the
UPPER
and
LOWER PANELS.
Disconnect the
AMPLIFIER PLUG
from the receptacle and remove the TONE
and VOLUME control knobs from the operating side. Re""-
move the three
AMPLIFIER SCREWS
holding the amplifier to
the platform and carefully withdraw the amplifier.
REMOVING THE AMPLIFIER PLATFORM
Service experience has shown that there is seldom need
for replacing brushes or the motor governor, but if it is
necesscry, proceed as follows:
To replace the motor, governor brushes, or governor,
it is necessary to remove the
AMPLIFIER PLATFORM.
Turn the
Kodascope on its side and use a broad-blade screwdriver
to remove the four roundheaded screws which hold the
platform to the base. Take out the three
COVER SCREWS
indicated in the illustration and the five screws around the
base of the cover. Lay the cover on its side. Do not dis-
connect the rheostat. and switch wires. lift the platform

position caps and withdraw the brushes. The motor
brushes are square; the
GOVERNOR BRUSHES
round. When
replacing the platform, be sure that the four large washers
fit around the feet of the platform.
REMOVING THE MOTOR GOVERNOR
Remove the nut and washer-cap from the
MOTOR RE-
SISTOR
and push the resistor to one side to provide clearance
for removal of the fan and' governor. Loosen the screw
in the hub of the fan and remove the fan. Loosen the two
screws holding the governor on the motor shaft. If neces-
sary, replace the round governor brushes. When re-
placing the governor, push it just for enough back on
the shaft to place the brushes under slight spring tension.
Position the governor on the shaft so that the two set-
screws can be tightened on the flats of the shaft. Replace
the fan with the blades bendinq toward the motor and
tighten the setscrew against the flat of the shaft. Replace
the washer on the motor resistor bolt and tighten the nut.
. ADJUSTING THE MOTOR SPEED
At sound speed, the sprockets should rotate at not less
than 178 or not more than 182 rpm. Use a tachometer or
coun! the revolutions. To increase the speed, turn the
GOVERNOR ADJUSTING SCREW
clockwise; counterclockwise
XII
to decrease the speed. Turn the screw one-half turn; then
recheck the speed.
Replace the amplifier platform. Be sure that the four
large spacer washers are around the platform feet and
that the feet are flat on the base. Attach the cover with
the ,eight screws.
Slide the amplifier carefully into place, taking care not
to strike the sound pickup rod. Fasten the amplifier to the
platform with the three screws and attach the two control
knobs. Adjust the
BUMPER BRACKET,
so that there is approxi-
mately
Ys
-inch clearance between the bumper and the
photoelectric-cell box. Attach the amplifier plug.
REPLACING DAMAGED SOUND
PICKUP ROD
Remove the flywheel (see page Xl and ornplifler (see
page XI). Lift the felt washer from the end of the sound
pickup rod and remove the two screws from the
SOUND
ROD BRACKET.
Draw out the sound rod. Unwrap the foil
from the old sound rod and place it around the new rod.
The foil serves to anchor the rod to the bracket and to
ground the sound rod to the machine.
Remove the exciter lamp cover, hold down the
TENSION
ROllER lEVER
and pull the
SOUND DRUM
and shaft from the
bearing. Be careful not to damage the sound drum. Hold
down the small retaining spring below the sound rod
openinq and insert the end of the new sound rod with the
clear surface down and parallel t~ the glass of the sound
optics. Replace the bracket over the foil wrapping on the

No Sound From Film Altho Tubes Glow
1. No "background" is heard; volume control and
exciter lamp control fully advanced. "Background"
is normal to a properly operating sound projector and
is due largely to tube noises.
a. Speaker voice coil may be open. Test coil, con-
necting cord, and speaker plug (refer to loud speaker
and cord assembly diagram).
b. Remove amplifier and check:
(1) Condensers C-14 and C-15 (part No. 79826)
for shorts.
(2) Exciter Lamp Control R-17 (part No. 58426),
Resistor R-16 (part No. 78361), Condenser C-13
(with C-2 part No. 69301), Condenser C-11 (part
No. 58527), and Condenser C-16 (part No.
- - -798-2-2).
(3) Exciter Lamp Rheostat and Amplifier Switch
R-18 (part No. 78476) for continuity; also, wiring
to Exciter Lamp Socket (part No. 58343) and to
Amplifier Plug Receptacle (part No. 58337).
2. If "background" is heard. Plug in a high-impedance
microphone or phonograph pickup and listen for sound
reproduction.
a. If sound is now heard:
(1) Inspect photocell for proper position and for
good contact with spring clip. The cathode in a
normal cell has a brownish appearance; whitish
or "silvery" appearance usually indicates leakage
of air into the cell due to fine cracks in the glass
envelope or a broken seal.
(2) Inspect sound rod for breakage or misalign-
ment. See page
XIII.
b. If sound is not heard:
(1) Check grid clip on 6J7 tube for good contact.
(2) Check position of 6J7 tube in its socket.
(3) Test 6J7 tube in tube tester.
(4) Test all other tubes.
XIV
And New Fuses Blow Repeatedly
1. Test rectifier tube, oscillator, and output tubes.
2.
Check continuity of power transformer T-4 (part
No. 78335) with special attention to ,high-voltage
secondary winding.
3. Check sections C-9 and C-12 of No. 78677 Filter
Condenser Block for shorts; also check C-16 Condenser
(part No. 79822) for short.
4. Check amplifier connecting-cord wires 2, 3, 4, and
5 for short to ground. Terminals 6 and 7 will normally
show a very low reading to ground. It may be necessary
to disconnect wires 2 and 5 to distinguish between a
short in the cord and a short in condensers.
5. Check amplifier wiring generally for shorts or
broken leads.
LOW AMPLIFIER OUTPUT
1. Test all tubes. Check all amplifier voltages-refer
to amplifier voltage diagram.
2. Exciter lamp current may be low-radio frequency
thermoammeter will be required to check current.
3. Photocell voltage may be low. Accurate setting
(maximum 90 volts) requires the use of an electrical
. .
bridge circuit. Distortion and noise will be excessive
with voltage at too high a value and photocell will
deteriorate rapidly.
4. Extra extension cord not heavy enough to carry the
load.
