Special tape recorder "L60M3348" released in 1961. There is no information on it, there is only a letter from Sergey Viktorovich Litvinov from Moscow and he also provided photos of the tape recorder for the site. Yesterday I received a very interesting from a technical point of view, a four-bobbed six-head tape recorder "L60M3348". No information on it. I did not find the possibility of using a tape recorder away from the outlet. BP produces several separate stabilized feeds: 22 V, 1.9 V (2 pcs.), 2.8 V (2 pcs.). Perhaps there was a possibility of replacing the PSU with a battery with a voltage separator. Such a system was used later on a VM-70 tape recorder. This idea was pushed by a connector for connecting the power supply unit, indirectly - the handle of removing the power supply unit from the seat and one bolt for fixing the power supply unit, as well as installing the battery with its fixation with one bolt (middle). I do not exclude the use of a tape recorder as stationary for recording indoors, but why then does this whole circus disguise it as a suitcase, which travelers and holidaymakers often traveled with in the 60s? The fact that the tape recorder was not accidental in the suitcase not only the dimensions of the suitcase meticulously fitted under the tape recorder and four substrates inside on the bottom of the suitcase under the tape recorder, but also special stops on the lid of the suitcase for fixing the electric motor and power supply, say about themselves no fixtures, screws or bolts are not fixed. This is understandable, otherwise all this hardware would have been visible outside the suitcase. Its use was implied not only in a horizontal position, but also in a vertical one. This is evidenced by the mechanisms of fixing the reels present on it from falling off the seats, as on stationary verticals from the 1980s. I dare to suggest that this is the first attempt of Soviet engineers in the production of voice recorders to record a conversation outdoors (on the go). It can be called a dictaphone with a big stretch because of its dimensions.But probably for this reason they resorted to the method of veiling the tape recorder under the suitcase. Well, can not you hide it in the inner pocket of your jacket? I do not exclude the possibility that, as of 1961, it was the smallest tape recorder at that time. It is not clear the presence of the power buttons alternately microphone number 1, number 2 and number 3. I also got a microphone with a cord and a pad for connecting to a tape recorder. Unfortunately, the cord is cut, but it is fixable. On the microphone there is a pin-type device for its hidden fixation on the clothing items. From all of the above, there is the conviction that the tape recorder was originally sharpened by a hidden voice recording. The presence of four reels I can assume the following task - the duplication of recorded speech is of particular importance. Simply the developers tried to duplicate the recording from the accidental failure of the main one. This means that the tape recorder could be used for hidden voice recording, the technical error of which was excluded initially, otherwise the second attempt could not be. P.S. This is so, the thoughts in the ear, if you make a mistake in the assumptions do not seek. With a mass of unknowns, any hypothesis has the right to exist.
