Portable wire recorder. Produced in the USSR in the
60-70s for the KGB. Dimensions of the device 158 x 75 x
26 mm. Weight without batteries 500 grams. Wire on the coil is enough for
1.5 hours of continuous recording. Dimensions of the
coil 35 x 12 mm., Hole diameter
14 mm.Rewind time 1 hour. Power is provided from 7 v battery "BOR" elements of the
OR-2K (RC-63) Battery "DEAC", or the five elements of
"Saturn", placed in an external container. Also, the
voltage can be supplied from an external power source
via a special adapter that is inserted into the battery
compartment. Recording is carried out using a
microphone, "Neva", or "T-65", compact headset TM-2, or
a special adapter. No built-in speaker, listening to
records by using the headset TM-2, or an external
amplifier. To connect a microphone, headphone jack and
adapter provided with the marking "M". The other two
connectors are designed for use by remote control
switch. To do this, gets out of the middle connector
plug and connector plugs are inserted into the remote
switch in accordance with the color-coded. The plugs
have a diameter of 3 mm, and a few turns of thread at
the base needed to prevent accidental jumping down from
the plug connectors. For good fixation of the plug to be
inserted into the slot until it stops, and turn several
times clockwise thread.
Device management is carried out by a switch that off
in the middle position "Stop", marked on the housing
cover in blue circle. When you switch the switch to the
position marked with a red circle, and closed the top
cover, the recording, while the open - to play. Rewind
the wire is carried out with an open lid and switch the
switch clockwise until it stops.
Wiring the recorder collected on five transistors. Three
of them (MP13B - 1 pc., MP41A - 2 pcs.) Are used in a
universal amplifier, one (MP41A) - a universal bias in
the generator head, and one (P213A) - in the motor
control circuit with a centrifugal regulator. To reduce
the interference power amplifier is placed in a shielded
enclosure. Connectors, electric motor control circuit
and the bias generator is assembled on a single board,
located in the edge. To adjust the volume and level of
writing is an attenuator with three fixed positions.
Erasing head no, and deletion of records throughout the
reel just by using a special demagnetizing inductor.
The mechanism of the device is well designed, and
manufactured quality. The only rubber belt transmits
motion from the engine to the flywheel horizontally
placed, which, in turn, rotates one of the two rubber
faceplates, depending on the mode of operation is
included. Universal head is moving up - down with the
worm gear mechanism. There is a hitchhiking, triggered
when the supply reel wire ends. At the same time in the
spring-loaded lever is released reel-held coils of wire,
and presses on the lever hitchhiking underneath the
supply reel. He opens the contacts the food chain motor.
More information about the design of the recorder is in
the instructions posted at the bottom of the page.
Factory equipment provided for the necessary set of
accessories, some of which I have available. Together
with the unit I received four additional reel, two of
them with wire, AC adapter, the adapter record from an
external signal, the adapter for non-contact recording
of a telephone line, throttle erasing records, the
battery "BOR", a set of cups for the elements of the
OR-2K (RC -63), earphone TM-2 tube with a lubricant, and
a device for charging wire.
The unit is in good working order, which is surprising,
since it was constructed in 1973, and in the design of
rubber parts are available. Do not even had to change
the rubber belt, but I replaced the lubrication
mechanism. Wiring is also proved to be completely
intact, the quality of the voice recording is good.
