Portable Recorder - a toy. Produced in Japan in the
early 60's. Dimensions 160 x 64
x 40 mm. Weight
Power motor 1,5 v, two AA batteries connected in
parallel, the power wiring 9 v, battery type PP3.
Housing plastic. Kinematics of simple, on one engine,
without stabilization of speed. The engine is located
horizontally between reel tables, and the shaft,
acting on both sides of the engine, rotates either one
or the other rubberized reel table. Coil diameter 45
mm (1.75 inches) can hold the reel 10 minutes of work.
Circuit collected at 2-type transistors 2SB75. There is
one connector jack (3,5 mm) to connect the microphone
and earpiece. The volume control there, and erase head
is used instead of a permanent magnet. Nevertheless,
despite the simplicity of design, the machine makes a
good impression, and appearance, and quality of work. It
really can be used as a voice recorder.
It is also known for
producing a replica Tinico named Electra 707 Candid.
Perhaps there were other names.
Electron 52D. Soviet copy Tinico. Performed in Poltava in 1968,
or 1967. The exact date of commencement of production
has not yet been set. Operating Instructions began
printing in 1967, and the earliest known instance of the
recorder with the serial number 037 dated January 1968. Of course this is not an exact copy Tinico,
there are minor differences, and even some improvement.
For example, in the winding of the motor is fed 3 v, and
recording - playing a 1,5 V, but Tinico always 1,5 v.
Circuit collected at three transistors (GT109A - 2 pcs,
GT108A - 1 pc), without transformers. Slightly changed
dimensions - 160 x 67 x 44 mm, and the case became more
angular. Weight has not changed - 370 g. The quality of
manufacture of our apparatus is not worse than the
Japanese, and works, I think, even better.
Produced as more complex analogues of the recorder under
the names “Monacor”,
"Elektra 770", "Star-lite Pocket Mate".
On the surface, and structurally they are similar, but
in the past has a built-in speaker, speed of the engine,
and volume control.
Tinico was bought in working condition. It turned out
the old batteries, which also pose a collector's
interest. Electron 52D was purchased in Russia, and in working condition.
It took just spinning the engine by hand to re-establish
contact with the oxides of carbon brushes contact the
ease of comparison, both sets of structures, in the left
column Tinico, and to the right Ålectron

Tinico designed to work with piezoceramic
headset. Electron 52D - dynamic headphones.
