tape recorder. Made in Japan by "Dictaphone Corporation"
appears in the late 60's or early 70-ies. Dimensions 155
x 93 x 38 without protruding parts. Weight 750 g. Power
supply 7,5 v, five AA batteries. Made apparatus soundly.
Details of the kinematics Basically metal, but plastic
rollers. The engine is located horizontally, transmits
motion directly to the rubberized flywheel with tapered
roller. Flywheel mass is connected with further
kinematics belt. Second belt used for tape
counter. Circuit 9 transistors
(2SB22, 2SC537, 2SC693)
provides a good quality recording - playback. Even three
transistors assembled stabilizer speed. Externally, the
apparatus also looks very decent. The thing is
beautiful, and also equipped with a stylish microphone
control. However, everything inside was not so good.
Rubber coated wheel was completely destroyed. Rubber
turned into something resembling a pitch, and dispersed
in the quarter of the internal volume of a voice
recorder. In the photo are clearly visible black
smudges, it is the former rubber. Also destroyed were
the main belt. It turned into a viscous mass, such as
clay. In this second belt and rubber roller has remained
in good condition. All this had to wash and scrub away a
cassette recorders produced under the name Sanyo M-760.

Instead of rubber, I laminated flywheel new elastic
coating of silicone sealant. Of course, ideally do so
failed, and the uneven playing takes place, but for the
demonstration of this quality is sufficient. Also some
of the problems created a foam rubber pad on the
electronics board. She stuck to the board, and turned
into dust, which is filled all around during the repair.

forming a new coating of silicone sealant.
Switching modes is carried out using the slide switches.
At the edge of the shell are jacks for headphones and
microphone control. Next to the tape counter is a button
release the tape. Spring there are quite strong, and if
you do not hold his hand, then the cassette is really
thrown. There is also a switch to a temporary pause and
light - LED battery discharge.
The device was bought complete with a microphone
and leatherette cover. In the battery compartment were
flowed batteries. Marking of the issue to them
