OPERATING INSTRUC TIONS
Preparing the Crestwood for Recording -
1. Insert line cord in a convenient wall recep-
tacle of the proper rating.
2. Turn the volume control knob to the right -
pilot light will light up;
3. Place a full reel of tape on the right hand
spindle (11). Make sure the magnetic coating (dull
side) is on the right spindle (11). Make sure the
magnetic coating (dull side) is on the outside of the
reel.
4. Place an empty reel on the left-hand
spindle (22), and feed the end of the tape in the slot
located between the two reels and then through one of
the radial slots in the empty reel. HoId the end of
the tape and rotate the reel, in a clockwise direction,
four or five revolutions. The tape shoutd now be
firmly fastened to the takeup reel. The dull side of
the tape should face outward on the supply reel and
on the takeup reel.
5. Turn the ('Record-Play,'knob to the
"Record" position.
6. If a microphone recording is to be made,
connect the microphone to the ,.Mike, jack.
?. If a recording from a radio is desired, it is
recommended that the connector cord be connected
to the speaker voice coil, by means of the alligator
clips, and the other end of the cord plugged into the
microphone jack. It is also possible to make a con-
nection to the plate side of the detector tube.
This kind of connection may be desirable in some
cases, because any circuit deficiencies in the ampli-
fier of the radio will not be included in the recording.
B. Adjustthe volume control so the neon
light level indic ator flashes intermittenily. Care
should be taken to adjust the input signal to such a
level that, with a setting of 4 on the volume control,
the neon level indicating light will flash intermittent-
ly. If the volume control setting for intermittent
flashing of the neon light is 3, or below, the input
signal level to the microphone jack is too low. A too
high level inpnrt signal will cause an overload in the
lzAxl amplifier tube, and, when played back, the re-
cording will be distorted. (Setting of the tone control
is immaterial. It is not in the circuit on ,,Record.r,)
9. Turn the control knob (1) to the ,,Forward,,
position. This engages the drive mechanism and
begins the recording.
10. To stop the recording, turn the control
knob (1) to the "Stop" position.
The Crestwood is designed for two-channel record-
ings; therefore, when the full reel has been recorded,
the two reels should then be interchanged, without
rewinding, and the procedure, as outlined in steps B
to 10, repeated.
To Rewind -
To rewind a recording, merely turn the control knob
(1) to the "Rewind" position.

To Play a Recording -
1. Insert the line cord plug into a convenient
wall receptacle of the proper rating.
2. Turn the ,,Vplume', control knob to the
right - pilot light will tight up.
3. Place the full reel of the tape on the right-
hand spindle (11). Make sure the dull-coated side is
on the outside of the reel.
4. Place an empty reel on the left-hand spindle
(22) and feed the end of the tape in the slot located
between the two reels and then through one of the
radial slots in the empty reel. Hold the end of ttre
tape and rotate the reel, in a clockwise direction,
four or five revolutions. The tape should now be
firmly fastened to the takeup reel. The dull side of
the tape should face outward on the supply reel and
the takeup reel.
5. Turn the '(Record-Play" switch to the
"Play" position.
6. Turn the control knob (1) to t'Forurard"
position. This engages the drive mechanism and
begins the play-back.
7. Adjust the Volume and Tone controls to
suit.
AD JUS TM E NTS
An open Record Head (10A) or Erase Head (10) must
be replaced completely; however, a worn-out, or
damaged Record Head or Erase Head lamination can
be replaced as follows:
Remove entire head and bracket assembly (15) with-
out disturbing the individual heads. On record head
(10A), remove record head laminations by prying out
with a screw driver. Press in new laminations with
your fingers until laminations are seated in the yoke.
The erase head lamination can be replaced in the
same way.
Identification of th6 laminations follows:
Record Head Lamination - Small Gap (.0005" )
ffibrassstrip.
Erase Head Lamination -Wide Gap (.010")
ffibrassstrip.
Overall width on Erase Head (10) is greater
than Record Head. Since the Crestwood is a
two-channel machine, it is important to replace
Iaminations with the steel sections uppermost
in the Tape Guide.
Motor. Power and Erase Switch -
The motor power switch (42) is set with the motor
in the "Stop" position so that the contacts are open
by the brazing action of the switch blade against the
bakelite pin in the motor swing plate.
The Erase "Safety" switch (43) is mounted in the
neutral "Stop" position so that the contacts are open
and a gap of approximately 1/16" appears between
motor mounting assembly (51) and the insulating
bushing on the switch. The switch is so adjusted that
