Dictaphone
Dictet Recorder. Manufactured
"Dictaphone corp. New York "U.S. It is knownthat these
recorderswere producedin the second
half of the50s, the
first mention of itI foundin
the Januaryissue of the
magazine"Tape Recording"for
1957. Known that these
recorders were made in the second half of the 50-ies.
This is a serious and perhaps a professional staff,
particularly interesting because it uses the original
cassette tape width ¼ inch. Other models, to use such a
tape, apparently does not exist. Dimensions 143 x 79
tapes x 11 mm.Weight: 125 grams. Case metal, cast aluminum, which are
located inside the coil with tape, and metal. On one
side you can do 30 minutes of recording at a speed of
6.3 cm / sec.

Construction recorder Basically metal. His weight 1,2 kg.
Dimensions 160 x 113 x 50 mm. It consists of a body in a
box, and deck, which is placed kinematics and
electronics. The soundboard is inserted into the body
from above. Housing cast, made of light aluminum alloy.
It is the battery compartment for the three batteries.
The engine used on 2 mercury batteries to 6 v, and
another 6 v battery powered electric system. Batteries
power the engine were designed for 20 hours, and battery
wiring for 40 hours. They are inserted through the
rectangular window in the side of the hull, and screwed
the lid closed. Inside the case there is a four-pin
connector, which derive power from the batteries. The
deck also has a jack that plugs into the connector body
at assembly.
Kinematics
of the recorder made very high-tech. Traffic on the
flywheel - capstan transmitted from the engine through a
system of gears and belt. Flywheel mass is connected
to the node winding gear, and to rewind is a rubber
roller. Due to the fact that you are using a lot of
gears, the mechanics of a rather noisy. To control
regimes, there are two lever, located on the front of
the chassis. One of the knobs - "On - Off", the second
- "Record - Rep - Rewind". Unlike modern cassette
recorder, capstan and the pinch roller in this design
are located in the middle, and head to one side.
The rectangular
box located in the corner, is a filter feeding the
engine
All the mechanics made very accurately, safely, and
still works properly. Wiring 4 transistor type 2N77
also works properly, except for the fact that 50 years
have dried some electrolytes. In the recorder is no built-in
speaker, and the use of headphones is not provided.
Function headset combines a microphone. Its cable
connects to the voice recorder 5-pin connector. Sound from a microphone - the dynamics becomes
quite loud, but keep it near your ear is not very
convenient, one hand turns all the time busy.
Microphones also issued with a button remote control,
which was provided for the inclusion of a chain lock.
To adjust
the volume and level of writing used by two separate
regulator. Erase head is not electric, but has some kind
of incomprehensible complicated design with two
adjusting screws.
The existing instructions I published that tape recorder
worth $ 289.00, and $ 8.75 cassette. In the Internet I
found information that in 1960 it sold for $ 314.00,
equivalent to 2 250.00 $ money today. Also, this
recorder is called the world's first cassette tape
recorder.
The device was bought in good condition,
complete with a microphone - speaker, the original
instruction, a family cluster in their original
packaging, and high-quality leather bag shoulder mount.
To bring it in working condition needed replacement
belt and some dried electrolytes. Also had to combine
advanced batteries for power and make a temporary
battery cover, which was not available. In the future we
plan to make this cover of aluminum to completely
restore the original design.
