GENERAL INFORMATION
The Wilcox-Gay "Recordio" Model 3FI0 features fingertip operation f or Fast Forward, Play-
back, Stop, Record and Fast Reverse. The "Recordio" is designed to record and play back two
tracks of material on standard width recording tape, which doubles the playing time of a standard
5" or ?" reel of tape with no loss of frequency response or quality. Recordings can be made
from a radio, television receiver or phonograph, in addibion to those made directlyfrom the
rnicrophone. Recordings can be played back through the seU-conbained speaker or an external
speaker through use of the Auxiliary Speaker Jack.
This "Recordio" has two tape speeds, 7 l/2" and 3 3/4" per second. Using both channels of the
tape, the recording time is as follows:

OPEFATING INSTRUCTIONS
I. With the "Stop" button depressed, insert the
AC power cord into the receptacle at the right side
of the cabinet (Figure I).
2. Plug the AC cord into a convenient wall
receptacle of the proper rating.
Threading the Tape -
I. Place a reel of tape on the left spindte (a)
and an empty reel on the right spindle (8) making
surethe reel slots engagethe reelpin on thespindles.
2. Unwind about 14" of the tape from the reel.
HoId a section of the tape straight with both hands
and insert the tape in the tape slot making sure the
dull coated side of the tape f aces the rear of the
recorder.
NOTE: This recorder u s e s Type "A" wound tape,
i. e. the dull magnetic coated side faces in-
ward on the reel. If the tape to be used is
Type "B" (coated side facing outward) place
the reel on the left spindle so that the tape
will lead-off in a clockwise direction. Bring
the tape behindthe rear cover (5)(not
through the head slot) and thread it on to the
right reel in the normal manner. Press the
"Forward" button and allow the full reel of
tape to wind on the empty reel. The duII
side of the tape wiII now be facing inward on
the reel.
3. Insert the free end of the tape through the
hub of the right take-up reel and place a pencil
firmly over the tape, forcing it into one of the three
Page 2
radial slots on the hub of the empty reel. Turn the
reel several turns with the pencil in this position
until the tape is secured to the reel and all slack is
taken up between the reels.
To Record From Microphone -
I. Turn the On-Off Volume Control to the right
until a click is heard and allow about thirty seconds
for the unit to warm up. The pilot light located
above the "Stop" button will glow when the unit is
turned on.
2. Insert the microphone plug into the "Micro-
phone Input Jack".
3. Turnthe speed control knob(I)to the deslred
speed.
NOTE: Recordings made at a certain speed must be
played back at that speed.
4. Move record lock Iever (18) downward with
the left hand. This releases the record safety lock
which prevents accidental erasure.
5. Depress the "Record" button with the right
hand (while holding the record lock lever (I8) with the
Ieft hand) until it latches.
6. Whiie talking into the microphone, adjust
the "Volumen control until the "Normal" indicator
f.Iashes and no flashing occurs at the "Overload"
indicator.
NOTE: Correct recording volume is very important.
Too weak a signal, which does not cause the
"Normal" indicator to flash, will re sult in
weak playback and high background noise.

Recordings can be rnade from a radio by placing the
microphone near the loudspeaker of the radio;
howeve r, this type of recording may not be satis-
factory as other sounds may be picked up by the
microphone which as a result wiII be recorded on the
tape. A superior quality recording can be rnade by
use of radio-phono attachment cord (Part No.
C-20.233). Connect attachment cord as follows:
I. Connect the cord clips across the voice coil
terminals on the radio speaker as shown in
Figure 4.
2. Insert the cord plug into the "Radio, TV,
Phono Jack".
3" Proceed as described in "To Record From
Microphone".
NOTE: Remove attachment cord after recording is
completed.
To Record From Phonograph -
I. Connect the cord clips of the attachment
cord to the pickup leads on the external phonograph.
2. Insert the attachment cord plug into the
"Radio, TV, Phono Jack".
3. Proceed as described in "To Record From
Microphone".
I. Connect attachment cordas describedin
"To Record From External Radio" and proceed with
recording as described in "To Record From Micro-
phone".
NOTE: The "Recordio" Tone Control does not oper-
ate during recording. When recording from
radio or a television receiver set the radio
or television tone control for maximum
treble.
DuaI Track Recording -
The Recordio is designed so that L/ 2 the tape width
is recorded at a time; thereby resultingin two
track recording. This two track operationis
accomplished in the following manner:
I. After a reel of tape has been recorded,
i. e. all of the tape wound on to the take-up
reel, depress the I'Stop" push button. This
stops all movement of the tape.
2. Remove the reels from the recorder,
turning the fuII reel over and placing it on the
Ieftspindle andthe empty reel onthe right
spindle.
3. Properly thread the tape and proceed with
the recording as in I'To Record F r o m Micro-
phonett.
Page 3

Figure 4.
4. After this track has been recorded the
f i r s t track of recording is ready to be played
without rewinding.
(a) Place the futl reel of tape on the feed reel
(lef t) spindle and the empty reel on the
take-up (right) spindle.
(b) Thread the tape making sure the duII side
of the tape faces the record head.
(c) Set the controls as described under "To
Play a Recording".
To PIay a Recording -
1. Thread the tape as described under
"Threading the Tape".
2. Turn the On-Off Volume control on and
allow thirty seconds for the tubes to warm up.
3. Depress the "Play" button until it is
Iatched into position.
4. Adjust the Volume and Tone control to suit.
-
Any size speaker of the permanent magnet type,
having a 3 ohm voice coil, may be used by connecting
a speaker extension cord acorss the voice coil of the
speaker and then inserting the extension plug (same
type as micorphone plug) into the External Speaker
Jack located on the r i g h t side of the cabinet. This
automatically cuts out the seU-contained speaker.
To Edit and Splice Tape -
NOTE: Since it is impossible to edit and splice
one track without affecting the other, re-
cordings which a r e to be edited should be
Iimited to one track only.
I. T h e tape may be edited by cutting out un-
wanted portions, or by joining selections into an-
othe r sequence. Announcements m ay be inserted
Page 4
betweenselections, etc. Unused sections of tape
can be spliced together for re-use,
2. For best results, cut tape at a slight di-
agonal, join ends together with splicing tape on the
glossy side and trim off any excessive width.
Fast Forward and Fast Rewind -
High-speed forward or reverse wind can be obtained
by pressing the desired button. These are used
primarily in locating a desired portion of a record-
ing in a few seconds.
CAUTION:The "Stop" button should always be de-
pressed before changing functions or
speeds. AIways depress the "Stop" but-
ton when the Recordio is not in use.
Erasing Recorded Material -
Erasing of recorded material takes place auto-
matieally when new material is recordedl there-
fore, no special step is necessary to erase
recordings before new recordings are made. How-
ever, if a portion of a recording or an entire reel
of tape is to be completely erased, do so as follows:
1. Properly thread the tape on the rn a c h i n e .
2. Turn the Volume control knob clockwise
until a click is heard. This turns the recorder
on.
3. P r e s s down on the Record button until it
Iatches into position. The erasing of recorded
material is now in process and may be stopped
at any time by depressing the "Stop" button.
NOTE: OnIy one track of recorded material is
erased at a time. To erase the second
track, reverse the reels and repeat the
above operation.
To Use Recorder as a Public Address System -
The recorder may be used for public address with
or without recording the material at the same time.
Plug in an external speaker asdescribedin"To
Use an External Speaker". Turn the recorder on
and depress the Record button, but do not use tape.
Be caref ul to maintain sufficient distance between
the microphone and the external speaker to prevent
feedback howl. ffitis desired to record thepro-
gram, thread the tape as previsouly described
before depressing the Record button.

good recorded tape on the machine.
3. Set the controls as described under "To
PIay a Recording".
Grip the vertical portion of the record head mount-
ing bracket with a p a i r of long-nosed pliers. Rock
the mounting bracket and record head f rom side to
side slightly until the maximum high frequencies are
obtained. Bend the bracket with the pliers to obtain
a permanent set at this position.
4. Replace the rear cover excutcheon (5).
Pressure Pad Adjustment (See Exploded View) -
I. Remove the front and rear escutcheons
(5 and lI).
2. Depress
the recorder on. the "Play" button. Do not turn
(a) The record-head pressure pad is adjusted
by the locked adjustment screw (44).
(b) The guide post pressure pad (43) is ad-
justed by bending the pressure pad spring.
It must be adjusted for minimum pres-
sure against the tape.
4" After the adjustments are made depress
the "Stop" button and replace the trim covers.
Erase Head Adjustment -
I. With tape properly threaded, turn recorder
on and depress the Record button. Allow tape to run
for a few seconds then turn recorder off, but leave
Record button depressed.
2. With the trim covers removed check the
erase head (120), see Figure 2, to see if it is
parallel withthe tape, if notloosen screw (22)
just enough so the head can be pivoted and align it
with the tape then tighten the screw.
CAUTION: Make sure the head retracting spring
(24), see Figure 6, remains in f ront of
the erase head while adjusting it.
3. Check to see if the top edge of the tape
coincides with the top end of the diagonal slot in the
erase head (junction of long diagonal slot and short
vertical slot). To adjust level of tape, Ioosen lock
nut (20), see Figure 6, and rotate tape guide post
(2I) to move tape up or down. Tighten lock nut (20).

not, loosen the forward adjustment screw (23) and
turn the screw in or out as required to obtain this
/64" adjustment. Tighten the lock nut.
5. Replace the trim covers.
Brake Shoe Adjustment - (See Figure b)
I. In order to adjust the brake shoes, the
complete mechanism must be removed from the
carrying case and the speaker disconnected.
2. With all push buttons in the up position
the brake shoes (70) should clear the drums by
approximately l/ 8,,.
3. Depress the "Stop" pushbutton while observ-
ing the brake shoes. Both brake shoes must contact
the drums at the same time and with equal pressure.
4. The ailjustment is accomplished by b e n d -
ing the spring arm (69).
Adjustment for Slow Take-Up Reel-
There are some instances where the spring drive belt
(9), see Figure 5, stretches aJter a periodbf time. In
this case, the belt should be removed and shortened.
Somebelts haveloops whichare joined toform thecon-
tinuousbelt. See Notebelowregarding shortiningbelt.
NOTE: The spring belt is made so that one end will
twist into the tip of the other endl therefore,
clip the turns off the large end of the belt.
1. Clip off 3 to 5 turns of the spring belt.
2, Twist the ends together and replace the belt.
Bias Adjustment-
Turn the recorder on and depress the "Record" but-
tonl use no tape. To determine if the b i a s is within
satisfactory limits without dismantling the unit, merely
connecta VTVM from the toplug of therecording head
to the chassis. If 75 to 100 volts are present no ad-
justment is necessary.
If the readings are outside of thi s range, proceed as
follows:
l. Try a new I2AY7, IZA)K?,6Ae5 and by3.
2. If still not within range, remove the chassis
shield and connect a low capacity VTVM from
Pin 2 of V2 to the chassis and ad just trimmer
M5 (see Figure 8) to obtain a reading of 2.2b
volts. This provides the optimum in perfor_
mance.
TROUBLES
Push Buttons Fail to Latch into position -
1. Spring (41) loose or broken, resulting in the
erase head (120) not being pulled forward to engage
the tape. See Figure 2.
2. Erase head not aligned properly. See
ItErase Head Adjustmenilt.

3" Check the recording tape to see if the dull-
coated side faces inward on the reel. If the duII side
faces outward, a recording cannot be made. If this
condition exists, wind the tape onto an empty reel,
as described in "Threading the Tape".
CLEANING
The recordhead, capstan and pressure roller are
sub j e ct to an accumulation of tape coating residue,
which is worn off the tape as it passes these parts.
Use a soft cloth and alcohol to clean the head sur-
faces, capstan and pressure roller.
CAUTION: Do not use a brush when cleaning the
recording head as this could possibly mar
the laminations.
LUBRICATION
AII rotating parts are provided with generous - size
oilite bearings, which are f actory lubricated and
require no further attention.
An occasional cleaning out of foreign matte r under
the plastic pushbutton cover is desirable, and a
smaII drop of oil on the sliding Iever members is
advisable.
Neon Record Level Indicators-
The ne on record indicator firing level adjust-
mentisonly required if a neon bulb is replaced. The
twoneonrecordlevel indicators are adjusted for cor-
rectfiringlevel bymeans of two trimmer capacitors ,
one for each indicator.
To adjust indicators proceed as follows:
1. Turn Recordio on and depress Record push
button.
Page lC
2. Connect a short jumper lead across the bias
oscillator coil, Ll (short out the coil to disable
the oscillator).
3. Connect an audio oscillator, set at 1000
cycles, into the microphone input jack. Output
of audio oscillator should be approximatety .01
volts. (A 1 vott output level may be used with a
100 to 1 reductionpad of resistors inserted be-
tween the audio oscillator and the microphone
jack).
4. Connectprobe of lowcapacilytypeACVTVM
to junction of 2-330KQ resistors, R27 and R28 ,
(mounted on terminal strip near volume control) .
5. Adjustvolumecontrol to obtain a reading of
36 volts on VTVM and leave control set and
VTVM connected.
6. Disconnect shorting jumper from across bia.s
oscillator coil.
7 . Adjust Normal indicator trimmer(M6A) fully
clockwise and then turn slowly counterclockwise
so that upon loosening the trimmer the Normal
neon bulb barely lights. This adjustment must
be made loosening the trimmer.
8. Short out bias oscillator coil.
9. Increase volume control to obtain a reading
of 88 volts on the VTVM.
10. Remove short from bias oscillator coil.
11. Adjust Overload indicator trimmer (M6B) as
described in step "7", for just barely lighting
the Overload indicator bulb.
IMPORTANT: Do not readjust the recording bias os-
cillator adjustment a"fter setting the in-
dicator light adjustments.
