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 .

ADJUSTMENTS
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

bearing. Clean flywheel and shaft assembly (89) ,
drive area only, also reel pulley(?0) drive area
witha suitable solvent, Relubricate idler bear-
ing and reassemble in reverse order.
4. If noise still exists in "Forward" or "Fast-
Forward"position check the reel shaft assembly
(10). Rem ove wing nut (?3) and spring (?2) ,
washer (71), reel pulley (?0), clutch disc (68),
pin (67), U-washer (66), washer (65), retaining
ring (64), fibre washer (63), reel pulley assem-
bty (10) and fibre washer (12). Clean and in-
spect all parts for wear or damage. Clean the
bearing in the reel support assembly (62) and
inspect bearing. Relubricate and replace any
defective parts and reassemble in order shown
on exploded view.
Pinch Roller Adjustment-
If pinch roller is damaged or out of adjustment,
clean and adjust in the following manner:
1. Toclean thefollower leverassembly (23) and
the pinch roller lever assembly (22), remove
springs (20 and 24), and retaining ring (21).
Remove both assemblies and shaf t attached to
mechanism plate. Clean thoroughly, removing
oldgrease and dirt, and relubricate. Reassem-
ble in reverse order. Adjust tab on follower
Leverassembly (23) so that pinchroller (22) en-
gages flywheel capstan just before lever (54)
releases supply reel pulley (9) from "Stop" po-
sition to "Forward". This prevents flare out of
thetape inthe supply reel, from "Stop"to "For-
ward" position.
MAINTENANCE
Cleaning The Play-Recor4 Head-
Theplay-recordhead is subject to anaccumula-
tion of tape coating residue which is worn off the tape
as it passes the head" This should beperiodically re-
moved since it may cause faint recordings and poor
playback. Wipe off the record and erase head contact
surfaces carefully with a clean cloth. If dirt is caked
orhard and willnot come off with a dry cloth, dampen
the cloth slightly with carbon tetrachloride.
NOTE: Donot use abrush or exeessiveamount of sol-
vent on the head surfaces,
Lubrication-
On normal use, the Ekotape requires a limited
amount of lubrication. Motor, flywheel shaf t, reel
spindles, pinch roller assembly and idlers operate in
oilite bearings. Whenever unit is disassembled for
repair, clean all bearings, cams, and levers, and
lubricate the following:
1. Lubricateall oilite bearings withSAE 20 oil .
2. Lubricate all cams and levers with Liqui-Moly
NV Grease or equivalent.
3. Appty a thin film of lubricant on the working
areas of parts.
NOTE: Do notuse cleaning solvent on oilite bearings.
Do not overlubricate, Ex
