Mriya - Soviet portable
transistor radio and turntable.
This specimen was made in 1968, and it was
probably started on the 67th. The functional
design is very attractive, except for the record player
there is a receiver with two KW bands, plus LW and MW.
Dimensions are quite compact 270 x 165 x 87
mm, weight without batteries is only 1.9 kg.
The appearance is also
quite decent, there is a good cover, there is even a
cover for a metal disc-stand, which is conveniently
fastened with straps when carrying.
All this works quite well, but my
specimen has a serious drawback, an unpleasant timbre of
sound. The
volume is good, no distortion, but the sound is like a
can. Through good headphones the same, that is,
the speaker is not to blame.
Perhaps other such radio receivers sound
normal, and there is a defect in my device that I have
not yet found, but if it is not, then it's sad, since
the design as a whole is good.
The wiring diagram
is assembled on 9 germanium transistors, see the bottom
of the page. There are no remarks on the mechanics of
the player, it's done normally, there are three speeds,
33, 45, and 78 rpm. The metal disk included in the kit
is installed under the plate, and in addition to the
function of the stand, it acts as a flywheel. At all
three speeds, the movement is uniform and stable. Of
course, for the power supply of the engine required and
the corresponding batteries, there are used 6 elements
of type D. They significantly heavier the design, and
according to the passport its weight with the batteries
is already 3.6 kg. All the parameters of the radio are
in the instruction, which is located at the bottom of
the page. The device went to me in working condition,
only preventive maintenance and some cosmetic works were
required.

A disc-stand with a diameter of 174 mm,
and a thickness of 2 mm weighs 370 g. For this design,
this is a really useful thing.
Without it, even a
small diameter disc is held unsteadily on a small table
The photo below shows how convenient the
disk in the case is fastened to the cover of the radio
 
 
Externally, the electronics board looks
pretty decent, no traces of interference
 
Rubber rollers of course from the time
zadubela, but still able to perform their functions
The motor with a centrifugal regulator.
It was necessary to carry out
its prevention
