Grundig DeJUR Versatile III .
Produced in 60-ies in Germany, and was considered a very
successful model in a pocket voice recorder. This unit
is really a pocket. Its dimensions are in the collection
of all 163 x 60 x 35 mm. And without the removable unit
(microphone, he is the speaker), it becomes even shorter
than 30 mm. Weight 400 g. Power supply 4,5 v, three AA
batteries. Everything is made of light materials.
Housing bakelite and plastic tape. Also, the apparatus
was manufactured under the name of Grundig EN 3. Perhaps
the differences between them are, but apparently they
are absolutely identical.

At that time it was one of the smallest and lightest
tape recorders. Designers are very well placed to
exploit opportunities for miniaturization of all the
construction sites. The whole volume of the shell is
used, there is almost no unused space. Most importantly,
is the original tape, the coil in which are located in
one plane. She repeats the form of a voice recorder, and
in the prescribed form as it is part of his body. This
is an ideal solution for economies of scale. Tape has
dimensions of 133 x 60 x 15 mm. Coil diameter 46 mm (1.8
inches) can hold a tape width of ¼ inch by 20 minutes of
recording. Cassette can be reversed, and record on the
other side. In case there is a window through which to
monitor the flow of the tape.
labeled EN 3.
When the tape is removed, allows access to the battery
compartment on three AA batteries. Kinematics of simple
but well thought out. Rubber rollers transmit the motion
kinematics directly on the edge of a tape reel.
Strangely, it works well. The compact engine has
electromechanical stabilization rate. He has a
centrifugal regulator, and wiring is the stabilizer of a
single transistor. Surprisingly, but in such a simple
kinematics of the ear can not be understood that the
belt speed is not stabilized. I rewind the tape several
times, and anyway, returning to the control record, I've
heard almost undistorted voice. Wiring is simple,
performed on a single chip, and takes up very little
space. Not what regulators there. This is probably due
to the initial objective of miniaturization. Erase head
replaces the permanent magnet. Manage voice recorder
made by one of slide switch. It is situated in a
convenient location corps, just where is the thumb, if
you take the tape recorder in hand. In four switch
position, - "record", "off", "playback", "rewind". There
is protection against accidental inclusion. To move a
switch, it must shift up or down. At the end of the body
recorder is Bipin unit connector microphone - speaker.
Playback volume is weak, and to listen nado hold the
recorder to his ear. However, given all of the positive
features of the device, you can forgive the designers.
Total Recorder makes a very good impression, and quality
of work, and appearance. His and today it is can be used
for other purposes. In the complete set has a beautiful
cover of hard plastic, which looks particularly
impressive voice recorder.
The device was bought in working condition.
