     Electronica M-402S.    Portable stereo cassette recorder. Made in 1989 in the USSR in Zelenograd factory precision engineering. The device is interesting, made quality and the design is also good. Case of good plastic assembled and disassembled easily, without pressure, all the screws and anchors are definitely in place. Special attention should kinematics recorder. Its design is complex, made of metal, and the quality of manufacture is similar to a military unit. The same kinematics used in tape recorders Electronica M-401S is also commendable.
     Wiring assembled transistors and hybrid circuits. Works pretty well recorder, sound pleasant. There hitchhiking, switches pause and select the type of tape Fe-Cr, volume and tone controls, and power LED. Tape dimensions 220 x 115 x 40 mm. Weight without batteries 560 g. Power supply 4,5 v, three batteries type C, or AC adapter. A built-in electret microphone, plug an external power input jack, and a connector for stereo headphones and an external amplifier.
     I got a tape recorder in good structural condition, but not intact. As is often the old tape, rubber belt into a tarry mass. The same thing happened with the tires of one of the clips. In order to clean the soiled parts had to partially disassemble the kinematics. After cleaning and lubrication, and the replacement of the rubber belt and rubber roller, the machine will function normally, and other defects not found.

Photos can be enlarged

On the increased photos it is well visible, in what rubber belt and one of rollers has turned

In the photo above right kinematics partially disassembled. On the left at the bottom of the details that had to be removed for cleaning. In the photo at the bottom right kinematics after cleaning and installing new belt. I should add that I installed belt is not as it should be in reality, but I would prefer to do
