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.

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

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.

Turn the MOTOR CONTROL knob to SOUND SPEED.

Be sure the EXCITERLAMP CONTROL knob is turned

beyond ON as far as it will go.

Turn the

CONTROL SWITCH

to MOJOR and check to see

that the film is running properly. Then turn the control

switch to PROJECTION LAMP. The thread light is

turned off automatically when the control switch is

turned to PROJECTION LAMP.

Focus the Kodascope by turning the lens back and

forth until the picture is sharp.

If the picture shows a blank strip or the edge of the

next frame at the top or bottom of the projected

picture, move the

FRAMING LEVER

up or down.

THREADING

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

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.

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

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.

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

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

oiling.

Use Kodascope oil or an oil of similar body. Do

not

use

light oil.

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.

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

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.

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

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

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

-inch clearance between the bumper and the

photoelectric-cell box. Attach the amplifier plug.

REPLACING DAMAGED SOUND

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.

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.
