GENERAL INFORMATION

The Webster Electric Ekotape Recorder Model?LZ is for custom installation and has no

cabinet, orcarryingcase. TheModel2l2isdesignedto record and ptay back two tracks of mate-

rialonstandardwidthrecordingtape, which doubles the playing time of a standard 5'* or ?t'reel

of tapewithnolossoffrequency response or quality. Recording can be made from a radio, tele-

vision receiver or phonograph, in addition to those made directly from the microphone.

The Model 2t2 has two tape speeds, 3 3/4" and 7 112" per second. Using both tracks of

the taperrecording time is as follows:

OPERATING INSTRUCTIONS

Preparing The Ekotape For Recording-

1. InserttheAC power cord into the receptacle

on the right side of the unit.

2. Plug t h e AC cord into a convenient wall re-

ceptacle of the proper rating.

3. Place a reel of tape on the left hand or "sup-

ply" spindle (9) in a manner so that the tape will un-

wind in a clockwise direction.

NOTE: The Ekotape isdesigned touse Type "A"wound

tape, i. e. the dull magnetic coated side faces

inward on the reel. If t h e tape used i s Type

"8" (coated side facing outward) the recording

will be made at a very low sound level and the

playback will be almost inaudible.

4. Place an empty reel on the right hand or

"take-up" spindle.

5. Unwind approximately 10" of tape and, while

holding a section of tape straight with both hands, in-

sert the tape in the tape slot making sure the dull

coated side of the tape faces the front of the recorder.

Page 2

6. Insert the free end of the tape through to the

hub of the "take-up" reel, f orcing it into one of the

three radial slots. While holding the tape in this po-

sition, turn the reel several turns (clockwise) until

the tape is secured to the r e e I and all slack is taken

up between reels.

To Make A Recording-

1. After the recording tape has been properiy

threaded, turn the "On-Off" control to the "On" po-

sition.

2. Turn the mechanism control knob (2) to "For-

ward".

3. Turn the "Record-Listen" selector knob to

the "Record" position.

NOTE: The "Record-Listen" selector knob will stay

in the "Record" position only when the mech-

anism control knob (2) is in the "Forward" po-

sition.

4. Turn the "Volume" control clockwise until the

incoming signal causes the "Record Indicator" to

flicker occasionally. A recording is now being made

on the tape.

To Record From Microphone-

1. Insert the microphone plug into the "Mic. "

jack, located on the left side of the top panel.

2. Followthe instructions under the heading of ,

"To Make A Recording",

3. Best results will be obtained if the micro-

phone is kept closer to the source of sound than to any

walls in the recording area to prevent echos of the

sounds as they rebound off the walls.

NOTE: The microphone should be kept at least three

feet away from the loudspeakerduringrecord-

ing unless the "Speaker " control knob is in "Off "

position.

To Record From Radio Or

Television Receiver-

Recordings can be made from a radio or tele-

vision receiver by placing the microphone near the lou&

speakerl however, this type of recording may not be

satisfactory as other sounds may be picked up by the

microphone which as a result may be recorded on the

tape. A superior quality recording can be made by use

of Radio Cord Attachment. Connect attachment cord

as follows:

1. Connect the cord clips across the voice coil

terminals on the radio or television speaker,

2. A terminal strip marked Rad-Pho- Input is

provided on the bottom of the chassis, and the other

end of cord should be connected here.

3. Set the radio or television receiver for soft

playing, then operate the Ekotapecontrols as

described under "To Make A Recording".

To Record From Phonograph-

1" Connect the alligator clips of the Radio Cord

Attachmenttotheendsof thepickup leads of the phono-

graph and then connect the other end to the terminal

marked Radio-Pho-Input. Proceed with the recording

as described under "To Make A Recording.'.

NOTE: Shoulda hum develope from the above connec-

tions, reverse the cord clips on the pickup

leads.

To Rewind-

Turn the mechanism control knob (2) counter-

clockwise into the "Rewind" position. When the re-

winding is completed move the mechanism control

knob (2)into"Stop" positionand allow the tapeto come

to a complete stop before moving the mechanism control

knob to any other function.

Twin Track Operation-

Model212 is a twin-track unit, whichrecordson

approximately half the width of tie tape at one time .

1. To record a secondprogram onthe same tape ,

lift the full reel from the right hand spindle,

turn it over, and place itonthelefthandspindle.

2. Place the empty reel on the right hand spindle ;

properly thread the tape, and continue your re-

cording as describedunder "To MakeARecord -

ing".

NOTE: Since it is impossible to edit and splice one

"track" without affecting the other, recordings

which are to be edited should be limited to one

track only.

To Play A Recording-

1. With the tape properly threaded, turn the

mechanism control knob (2) to the "Forward" position .

2. Actjust the "Volume" and "Tone" controls to

suit.

3. Besure thespeaker "On-Off" switch, located

on the right side of the top panel, is in the "On" po-

sition.

Fast Forward-

If it is desired to reach a recording near the

endof atape ina few seconds, turn rrreehanismcontrol

knob (2) to the "Fast Forward" position. In the "Fast

Forward" position the tape moves ahead approximately

15 times normallistening speedof 3 3/4 or 7 L/2inches

per second. The most rapid fast f orward speed is

therefore obtained with the speed control set at 7 L/2 .

Pressure Pad And Lever Adjustments-

Cleaning, adjusting or replacing pressure pad

assembly and lever assemblies should be done in the

following manner;

1. Toadjustpressurepadassembly(28), remove

back cover (5) and top panel (13). To remove

assembly f or cleaning, repair or adjustment,

remove spring (29) and retaining ring (27). Ro-

tate the pressurepad assemblyslightly counter-

clockwise and lift off. Reassemble in reverse

orderand lubricate (see "Lubrication"). Adjust

byturning cam and shaft assembly (35A) to "For-

ward" position and check to be sure pressure

pads engage groove of head properly.

NOTE: Be sure flat of pad presses against the erase

and record p o I e pieces. To adjust properly ,

bend levers accordingly.

Improper Rewind Operation-

Ifthe unit doesnot perform therewind operation

properly, check as follows:

1. Adefective motorpulley(94) maybe the cause

of improper rewind. To replace a defective

motor pulleyassembly, remove the three mount-

ingscrews (103) from motor and plateassembly

(104). Carefully remove theassembly so as not

to damage the drive idler assemblies (?6 and 86).

Before removing the motor pulley measure and

note distance from hub to motor. Loosen the

twoAllen head set screws andremove themotor

pulley assembly, Reassemble with a new pulley

inreverse order, Be surepulley hub is correct

distance from motor as previously noted.

2. Adirty or defective supply reelshaft support

assembly (55) may be responsible for improper

rewind. To correctfaulty operation, clean, re-

pair or replace any damaged or worn parts.

Adjusting Brake Lever Assembly (45 and 54)-

If tape overruns from "Rewind" to "Stop" posi-

tion, adjust, clean or replace brake lever assembly

(45).

1. To ad just brake lever assembly (45), turn

camand shaft assembly (35A) to"Rewind" posi-

tion. Adjust either by bending the brake lever

assembly (45) or by slightly bending the stop on

mechanism panel just enough to clear the cup

disc on reel shaft (10). Clearance should not

exceed 1/64 inch. Adjust brake lever (45) so

that remote Iever (51) returns to "Stop" posi-

tion. Check to be sure brake lever (54) on the

supply reel (9) is being held in its stop position

Page 10

by the remote lever assembly (51). If not, turn

camand shaftassembly (35A) to "FastForward"

andadjust brake lever assembly(54) as outlined

above. Before reassembly of top panel, thread

recorder with tape and checkunit for any further

trouble.

2. If tape overruns from "Fast Forward" to

"Forward", check operation of brake lever (54)

as explained in above paragraph with this ex-

ception; turn cam and shaft assembly (35A) to

"Fast Forward" position and adjust brake lever

(54) on the supply reel (9). Check brake lever

(45) on the take-up reel to be sure it is held in

its stop position by the remote lever assembly

(51). f not, turn carn and sha"ft assembly (35A)

to "Rewind" and adjust brake lever as covered

in above paragraph.

Adjusting Brake Arm Assembly (113)-

If af ter completing adjustments as covered in

"Adjusting Brake Lever Assembly", the overrun on

"Rewind" and "Fast Forward" is not corrected, re-

move the unit from the case and check as follows:

1, Check "Rewind" position first and adjust or

replace brake arm assembly (113). First be

sure brake pad is still attached to arm. Turn

cam and shaft assembly (35A) to the "Rewind"

position and adjust the brake arm (113) so pad

just clears the reel pulley assembly (70) but by

no more than 1/64 inch.

2. Check "Fast Forward" position and adjust or

replace brake arm assembly (113). First be

sure brake pad is still attached to arm. Turn

cam and shaft assembly (35A) to "Fast For-

ward" position and ad just bral<e arm (113) so

thatthe pad clears reel pulley assembly (Ba) by

no more than 1/64 inch.

Correcting Take-Up And Fast

Forward Troubles-

If take-up and fast forward drive does not func-

tion properly, r e m o v e unit from case and check as

follows:

1. If the take-up or fast-forward drive is weak ,

screw the self-Iocking wing nut (?3) on the reel

shaft (10) s o spring (?2) will produce a greater

friction drive.

2. Ifafter adjustingthe self-locking wingnut

(?3) a weak drive still exists, then remove wing

nut, spring (?2), washer (?1) and reel pulley

assembly (?0) and check felt pad on pulley. If

pad is worn badly, replace assembly (70), but

if pad shows no excegsive wear, remove clutch

disc (68) and check to see i.f drive pin (6?) is in

place. Replace pin if missing and reassemble

in reverse order and adjust wing nut.

3. If unit i s noisy in "Forward" or "Fast-For-

ward" position, check to s e e if idler assembly

(110) isdirty or damaged, Or it may be the re-

sult of dirty bearings on the take-up shaft or

pulley assembly. To check, inspect idler

assembly (110) and determine if dirty or defec-

tive. Remove retainingring (112), fibre washer

(111), idler assembly (110), and fibr e washer

(111). Clean any dirt or oil from idler tire and
