From 1989 and 1991, household cassette tape recorders "Electronics VM-18" and "Electronics VM-32" produced Saratov Production Association "Tantalum" and Voronezh Scientific-Production Association "Electronics". VCRs Electronics VM-18 and VM-32 differ externally in the inscriptions, in VM-18 all the inscriptions are in Russian, and in VM-32 in English. The flip cover of the VM-18 was the entire length of the device, while the VM-32 only hid the Russian-language part of the keyboard. Inside: the video and color channel corresponds to the VM '' Electronics VM-12 '' channel and is made on the microcircuits of the 1005 series. The difference is only in the entered regulator of definition, for VM "VM-12" it was determined by factory settings. Radio VM corresponds to the television. The SAR block is made on the 1043 series. Brushless motor used. The principal difference from VM-12 (except for front loading) is in application instead of one LSI of VM-12, a control unit executed on a KR1820BE1 microcontroller, with a corresponding strapping from a heap of microcircuits (561, 1561, 573RF and 537RU), which expanded the service, gave the remote control, but they ruined everything that had been planned. The circuit consumed a lot of power, heating led to a severe thermal condition of the elements, which, with the quality of components then available, did not contribute to reliability. VM "VM-32" is interesting as one of the last domestic serial VM, made on the domestic element base. Here is a post from the magazine Radio No. 1 for the year 1990. At a number of enterprises in the country, they are increasing the output of domestic household video recorders. The outdated VM '' Electronics-VM-12 '' is replaced by the video recorder '' Electronics VM-18 '', the serial production of which is started by the software '' Tantalum '' (Saratov) and NPO '' Electronics '' (Voronezh). Modern appearance, frontal cassette loading, a large amount of information displayed on the luminescent indicator (calendar, current time, TV channel numbers, status symbols, dew signaling), IR remote control - all this combined with a reliable microprocessor control system provides VM increased consumer qualities. The signal processing parameters in the VM comply with the international standard VHS.The owner of "VM-18" will be able to watch videos and use the VM to automatically record a TV program in the MV and UHF with the help of 4 timer programs for 2 weeks in advance. Dimensions of "VM-18" 340x365x115 mm. Weight 8.5 kg. Circuit design and construction VM domestic. The company has been mastered in serial production at Tantal. Since I-sq. 1992, the VM "Electronics VM-18-2" was produced, which had insignificant differences in the LSM.
