The operating speeds are either 3 3/4 or 7 L/2 inches per second. The Webcor is designed to
recordandplayback two tracks of material on standard width recording tape, which doubles the
recording and playing time with no loss of frequency response or quality. Recordings can be
made from a radio, television receiver, or phonograph, in addition to those made directly from
the microphone.
The Webcor 2020 Series are mechanically and electricatly alike. The only difference being
in the cabinet, or carrying case used. The portable model of this series, zlz}risavailable in

L. When the stop button is depressed, the fast
"Rewind-Forward" Iever may be moved from its po-
sition, either to the Ieft or right.
2. When the lever is moved to the right the belt
engages the drum of the take up reel causing an approx_
imate 20-1 ratio transport.
3. Moving the lever to the left causes a similar
action on the supply reel.
OPERATING INSTRUCTIONS
-
1. PIug the AC cord into a convenient waII re-
ceptacle of the proper rating.
2. Place the reel containing the tape on the left
or supply spindle.
3. Placean empty reel on the right or "take-up"
spindle.
4. Unwindabout 12 to 15 inches of tape and guide
it into the tape slot. (Be sure the shiny side of the tape
faces the front of the cabinet).
5. Take the end of the tape and wrap it around
the hub of the empty reel. Bring the end of the tape
through one of the slots on the reel hub and revolve
the reel several times.
To Make A Recording-
1. After the recording tape has been properly
threaded, turn the "On-Off" switch and "Volume Con-
trol" to the rronrr position.
2. Press the "Speed Selector" knob (9) down for
7 -L/2I. P. S. operation or turn slightly to the left and
permit the button to raise for 3-3/4 I. p. S.
3. To record, pull the f tRecord Safety Lever" (b4)
downward, and at the same time push down firmly on
the "Record" button.
4. Adjust the "Volume" control so that the "Over -
load Indicator" barely lights on the recording peaks
and so that the "Normal Indicator" blinks constanily
during recording.
To Record From Microphone-
l.Insertthemicrophone plug into the t'Input Re-
ceptacle" located on the left side panel.
2. Follow the instructions under the heading of
"To Make A Recording".
3. Best results will be obtained if the microphone
iskept closer to the source of sound than to any walls
inthe recordingareato prevent echos of the sounds as
they rebound off the walls.
Page 3

Figure 4
NOTE: Themicrophone should be kept at least three
feet away from the loudspeaker during record -
ing.
To Record From Radio Or Television Receiver-
Recordings can be made from a radio or television
receiver by placing the microphone near the loud-
speakerl however, this type of recording may not be
satisfactory as other sounds may be recorded on the
tape. A superior quality recording can be made by use
of Radio Cord Attachment (part No. 2927). Connect
attachment cord as follows:
1. Connect the cord clipsacross the voice coil
terminals on the radio or television speaker.
2. Insert the cord plug into the "Input Receptaclel
Iocated on the left side panel of the recorder.
3. Set the radio or television receiver for soft
playingthenoperate the Webcor controls as described
under "To Make A Recording".
To Record Frgm Phonograph-
tr,. Connect the alligator clips of the Radio Cord
Attachment to the ends of the pickup leads of the phono-
graphandthen insert the cord plug into the "Input Re-
ceptacle". Proceed with the recordingas described urp
der "To Make A Recording".
NOTE: Should a hum develop from the above connect-
ions, reversethe cord clips on the pickup
leadg.
Page 4
To Rewinci-
When the stop button is depressed, the "Fast-
Rewind-Forward" lever (13) may be moved from its
center position. To "Rewind" move the lever to the
left. When the rewinding is completed move the mec-
hanism control knob (52) into "Stop" position and al-
low the tape to come to a complete stop before moving
the mechanism control knob to any other function.
Twin Track Operation-
Webcor 2020 Series are twin-track units, which
record on approximatety half the width of the tape at
one time.
1. To record a second program on the same tape,
Iift the full reel from the right hand spindle, turn it
over, and place it on the left hand spindle.
2. Place the empty reel on the right hand spindlel
properlythread the tape, and continue your recording
as described under "To Make A Recording".
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 mec -
hanism control knob (51) to the "Play" position.

Fast Forward-
If it is desired to reach a recording near the end
of a tape in a few seconds, turn mechanism control knob
(13) to the "Fast-Forward" position. For the 'tFast-
Forward" position the control should be turned to the
right. When the lever is moved to the right you have
approximately 20-1 ratio transport.
ADJUSTMENTS
Clutch Adjustments-
The nut (79) permits adjustment of the corres-
ponding clutch assembly. It should be adjusted so that
the take up reel absorbs the slack tape during the re-
cord and play operations. The clutch pad (?0) is 10b
oil saturated to permit a smooth take up and slipping
action when constant tension of the tape is attained .
Excessive tension may cause waver and tape squeal.
Insufficient tension may cause tape looping ahead of
the take-up reel, and a jerking action.
Erase Adjustment-
1. Insert a reel of recorded tape and press the
"Record" button.
2. Check to see if the surface of the tape makes
good contact with the surface of the shoe face. If it
does not, adjust screw (21A).
3. Checkto see that the top of the tape is exactly
positionedatthetop of the scribed diagonal line on the
Figure 5
Selector", Iocated on the shoe face. If it is not, adjust the threaded tape guide
in the speed that the re- (15) and the locking nut (14).
4. Turn the recorder "On".
5. Turn the volume control to minimum (full
counterclockwise).
6. Play the reel of tape through with the recorder
in the "Record" position.
?. Press the "Stop" button and rewind the tape.
8. Turn the volume control to maximum (full
clockwise).
9. Setthe recorder to the t'Play" position. If the
adjustments are correct, nothing should be heard as the
tape is played back. No audio output indicates proper
erase.
PIay/ Record Head Adjustment-
It is very important that play-record head (36)
be lined up perfectly with the tape, If it is not, low
output, loss of high frequencies or track overlap may
result.
