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.

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 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.
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.
I love to listen to the French speaking English. Sounds far better than me as a German speaking English. Not sure why I am watching this video. Interesting anyways, thanks for sharing!
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
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.

For civilian purposes opams would have letter K, К140УД1Б.
Exactly this.
These kind of Soviet equipment and technologie will work till the end of the time
Nope. Probably full of tin whiskers inside those cute semiconductor cans (transistors, diodes, ICs).
Absolutely Yep........Russian Built This Equipment Like Their Universally Most Reputed Battle Tanks ........ Maximum Durability With The Reliable Performances,..........
@@dizekat IMHO, there is much more gold inside these semiconductors than tin. The solder is also tin-lead.
Do we know that it works, or what it even does?

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.
I Love the soviet electronic ❤️
- yep, because it contains quantum satis of gold.
@@sentinel1064 I hate those types. Scavengers... Would dissolve their mother, if learn that she contains one gram of gold.

the enclosure almost looks like it might be explosive atmosphere rated.
Kyrilic "ВУ" in latin goes as VU. I'm guessing that stands for Vychislitelnoje Ustroistvo, meaning calculating unit.

У means УСИЛИТЕЛЬ (amplifier)
Ask Mr Hewes here in UA-cam, I believe is a device for finding direction for a T-72 tank upgrade, maybe anti aerial. Very good video!

what ukrainian wash machines do these ICs come from?
Да, это советская микросхема
What does it do ?
"So... What do we have in here? Nothing! Damn."Ahh, you tease!
Good device
У меня есть куча таких подстроечных резисторов (с 80х лежат).
The Layout looks like I did it. Everything way too far apart.
hahaha ;-)
Wish I could by one of these
This box dates back to which periode
It is early 1980's according to the detacodes on the componants.
its a soviet aircraft controller
