5:50 This is vibration protection. Soldered Legs are not reliable and the base area is small, the element is high. It is logical to put it on its side and use a large area for fixing with glue. In civilian equipment, they would do as you said, but not in the military. 140УД1Б are medium-precision operational amplifiers without frequency correction. Produced according to bipolar technology and designed to work in general-purpose radio-electronic equipment. The diamond icon on the elements of radio components means military acceptance. There is increased accuracy and reliability of the part. There are exactly the same details in the USSR, but without a rhombus - they are for civilian devices. Аll parts and the board are varnished to prevent from air humidity. Boards of 1973, judging by the markings.

For civilian purposes opams would have letter K, К140УД1Б.

Do we know that it works, or what it even does?

@icis4 9 ай бұрын

Not at all. The problem was the electrolytic capacitors. Typically, the devices worked for about 10 years, after which they became unusable. Chinese capacitors produced in 2000-2005 had the same problem.

The most interesting thing is that these tiny relays are still being sold. In Kazakhstan they cost me about 150 tenge, or about a third of a dollar.

@featheredskeptic1301 4 жыл бұрын

The IC's are op amps - 140УД1Б. Similar to µA702,H-2620,VC1539 according to the datasheet. There was probably some analog data processing involved, comparing, adding, subtracting input voltages, or calculating logarithmic/anti logarithmic functions or whatnot.

@@sentinel1064 I remember a contactor for critical circuits in electronics for nukes control equipment (RT-23 Molodets, rail based) - 12 contacts, 4mm diameter, 0.5g of 999 gold each, totalling 6 gramms, as per spec provided to the development team. Do not know where those ones ended up, more likely in the rubbish, after the programm been finished and nobody cared - stealing/ dealing gold in Soviet Union could bring you 7-8 years in prison.

The relays are mounted this way because their contacts are too close to fit the PCB design rules for this device. Notice how all components and their pins are spaced, and even opamps are mounted into a very widely stretching footprints.

Kyrilic "ВУ" in latin goes as VU. I'm guessing that stands for Vychislitelnoje Ustroistvo, meaning calculating unit.

Спасибо за обзор. Реле РЭС-49, никогда не видел, чтобы их так устанавливали. Судя по буквам в децимальном номере «БК», разработчик этого устройства ЦНИИ-173 и это некая измерительная система управления огнем, может быть от танка? Thanks for the review. Relay RES-49, never seen to be so installed. Judging by the letters in the decimal issue of "BK", the developer of this device is TsNII-173 and this is some kind of measuring fire control system, maybe from a tank?

См мой комент выше. Контакты у РЭС49 слишком близко расположены, и по используевшемуся там ГОСТу разводки платы их было невозможно установить. Не вписывалось в минимум расстояния между отверстиями, дорожками ну и тд.

@@yoksel99 легко так ставили "НИИ Стрела" Тула. Бывало ошибки в разводке платы - выводы не совпадали с тем что развели, вот и припаины проводами... и вторая причина - должны были стоять РЭС79, они меньше по высоте, а РЭС-49 на 5 мм выше, мешают сборке.

The ВУ on the front panel is likely ВЫЧИСЛИТЕЛЬНОЕ УСТРОЙСТВО which literally means "computer". Annotation Д (ДИОД) is for diodes, Р (РЕЛЕ/РЕЗИСТОР) is for relays or maybe resistors, T is obvious and I'm curious what У is for.

6:00, my two cents, They used glue/epoxy for vibration reasons, my guess is that they assume no maintenance so no need to be removable. horizontally to keep a low profile and minimize the risk of the upper circuit board hitting the relay. Look extremely sturdy if you ask me, the military way, although Russians do like it cheap and they normally take the cheapest option to solve problems, like here.

Hello! Good video! 7:00 there is a germanium transistor ГТ403 in the right bottom side (a silicon transistor on the right, and three resisitors on the top). I wonder - WHY is a germanium transistor in military electronics?The manufacture date - 1980 year.... not 1960

@sergej7490 8 ай бұрын

Sometimes was GE transistor used due to very small voltage drop and low base opening voltage (Vbe= 0,2V opposite 0,55V in Si transistor). BUT sometimes are this old parts used in special (schematics) blocks which function was verified many years ago.
