     Electronica M-401S.     Portable stereo cassette recorder. It is made in 1989 in the USSR on Zelenograd a factory of exact mechanical engineering. Under characteristics it really the tape recorder, instead of a dictophone or a player. Apparatus in all respects an outstanding, well thought-out design and build quality was too high. Kinematics is quite complicated, and is made of metal. The weight of the tape is acceptable, only 300 grams without batteries. Dimensions 145 x 32 x 88 mm, supply 3 v, two AA batteries. Frequency range 63 - 12 500 Hz. There is a hitch-hiking, built-in microphone, a switch-type magnetic tape Fe - Cr, temporary pause switch, power indicator, two headphone jacks, jack input connector and an external power supply. Included is a container for an additional battery power. In the container is inserted into the two batteries type C.
     The device has got me out of whack, but sealed the factory seal. Once opened, it became clear that the rubber belt and one of the rubber rollers have turned into a liquid mass, which had to scrub away a long time, and wash it smeared details. After installing a new rubber belt and rubber roller replacement unit operates like new. The recorder does give a good sound, they are pleasant to use, and in general it is a very good impression. This is a rare case among the Soviet Radio, where product quality can be assessed better than the Japanese.
