Electronica-video VMP-1

   

 

Used Google translator

     Electronica-video VMP-1.     Reel video recorder. Made in the USSR in Voronezh in 1975. Such recorders began producing in 1974, but later in the design have made some changes, and the tape got a new name - "Electronica-501-video". As often happened in the USSR, on its own development of household appliances do not spend money, but simply copied the successful foreign original. In this case, the prototype of these models are Japanese video recorders Sony AV-3400 and Sony AV-3420. The latter differ from each other recording standard, AV-3400 - 30 fps, AV-3420 - 25 fps.

Video recorder provides:
    - Sound recording and a black and white video from a TV or camcorder
    - The imposition of a soundtrack to a previously recorded with a microphone
    - Video playback on the camcorder screen and sound through headphones or through the TV
    - Still playback on a TV or video
    - Erasing of sound and video
    - Rewinds the tape in either direction

     Power is supplied from the AC adapter BPVM, or the battery voltage 12. The recording system is helical, two rotating video heads FM signal. Recording, playback - no less than 35 minutes on a reel. Passport belt speed - 15.88 cm / sec. Recording on a chrome-oxide tape 12,7 mm (1/2 inch) and a thickness of 27.5 mkm. Resolution - at least 250 lines. Audio range 100 - 10000 Hz. Dimensions of the video recorder - 295 x 272 x 153 mm excluding protrusions, legs, hands. Weight about 9 kg.
     Kinematics design and wiring video recorder "Electronica-video VMP-1" is nearly the same Sony AV-3400 and Sony AV-3420. Later model "Electronica-501-video" has some differences, particularly in the wiring added relay switching, and added a special connector for the TV. Read more about the similarities and differences between these recorders can be found on the page "Electronica-501-video".
     This recorder has got me in good structural condition, but faulty and no belt. After installing the new belt kinematics work correctly, URH (unit rotary heads) rotated, but the speed was not stable, and will not be synchronized. After repair tape works quite satisfactorily, given his age and the fact that it was made in the USSR. The device was presented to me by Dmitry Petrov.  

After repair the tape recorder works normally. Video footage, recorded from the TV. Photos can be enlarged

 

Record on video tape recorder " Electronics - video -1 " from recorder VHS

These video recorders manned the video camera such as "Electronica-841" and the power supply BPVM with charger function. Detailed photo camera can be viewed at "Electronica-841", and the power supply on the page "Electronica-501-video"

 

As seen in the photo below, external recorder survived pretty well

   

In the photo on the right is visible panel switching. To connect the camcorder and the TV uses a single connector RS-10

     Nameplate manufacturing date is missing. It should be placed in the battery compartment, but there is not even a trace of glue. Apparently it was not here at all. Year of manufacture is known from the best of my instructions. It is from this tape, the rooms are the same

             

The pictures at the bottom of the design of the rotary transformer, which is used instead of the current collector used in the Sony AV-3400

   

    URH this design different from URH modern VCRs that the video heads mounted on the beam, rotating inside a rigid drum - Housing URH. The housing consists of two halves, fixed so that between them there is a gap of about 1.8 mm. URH installed horizontally, and the gap, wherein the moving head is also horizontally, and the tape slides along obliquely drum Guide band, fixed on its surface. The desired trajectory of the tape gives the track struts and coil with the tape at different levels. In modern VCRs head mounted in the rotating drum URH, reel tape are in the same plane, and the drum is angled URH.
    More information about the structure of
URH, please visit Sony AV-3400. It should be noted that if you copy was based on the very first modification of Sony AV-3400, and the case URH there was just such a design, with Guide band.
On page Sony AV-3400 is shown later versions, and the Guide band on the housing there, but instead there is a corresponding protrusion formed in the manufacture of the body. In later versions
URH were also added three additional springs Pincher tape on top, and hold it in position on the surface of the URH.

I had the opportunity to delve into Sony AV-3400 early versions, and I made a few photos, including photos the URH from Guide band. See the photo below.

In the picture below on the left is one of the electronic boards to get a better shot was visible scheme of kinematics. Lower left - auxiliary motor. Above it a large double pulley axis is capstan. URH right, and above it a pulley, which is transmitted to the rotation mechanism for winding and rewinding
