Thank you for the teadown. It looks like when this board was designed, the bipolar transistor was still a new thing and tubes were here to stay. I have studied a few cold war-era electronic books and they have quite a few mistakes. They had a few good DDR engineers and don't want to take anything away from them but the few URSS people thar could design, code or jump emigrated early on.

1KLA7 (1КЛА7), full partnumber 564LA7 (564ЛА7), is a quad 2-input NAND gate. 590KN2 (590КН2) is a quad analog switch (voltage range from -10 to 10 VDC).
Another interesting item and excellent video. "The Kh-101 (Russian: Х-101; NATO reporting name: AS-23 "Kodiak") is a Russian subsonic air-launched cruise missile. Designed in the 1990s, it underwent testing in the 2000s and entered service in the 2010s, seeing use in the Syrian Civil War and the Russian invasion of Ukraine." So it's recent missile. 7 meters long. 3,500km range. Guidance system is inertial guidance with Doppler radar/terrain map updates.. Can have conventional or nuclear payload. 2,400kg weight.
The fact that the circuit board is made using cheaper technology does not make the missile any less lethal. Also, this part of the circuit does not have high-speed or high-frequency interfaces, which made it possible to make it on such a simple printed circuit board.
A samurai without a sword is like a samurai with a sword, but without a sword. A PCB without a mask is similar to a PCB with a mask, but without the mask. :)
So, this board is one small piece from an antiaircraft missile Buk. There are dozens if not hundreds of other boards in the missile, including a computer, some microwave circuits, etc. The particular model of the missile which this board came from was designed in 1990s, which was the lowest point for the Russian industry. The companies were not getting any orders, and the workers were literally not getting paid for months in a row. Crime and poverty were all around. This may in part be an explanation for why this board looks substandard compared to even the older USSR military hardware. But whatever its deficiencies, the rocket must have passed the tests and it had been in production at least up to 2013, the year when this board was made, and possibly much longer.

All military PCBs in Russia must have a code formatted in accordance to the federal regulations. The code on this board is not in the correct format. Despite that, this is certainly a Russian-made military PCB. All of the components are very expensive, military grade items. The smallest chips cost $10-30 and are hand-made and individually tested.

Yes, it was the oscillator. I don't know why, the power is quite small and the frequency not too high. It is the same for the guarding tracks, totally useless with the resistance values used in that circuit, when the guarding tracks are correctly placed.

@@lelabodemichel5162 Thank you so much. I will tell you the thing with these guarding tracks connected to the opamp output in the inverting configuration and not to the ground. In the schools of eastern europe they teach that the virtual earth point (after the input resistor) has some resistance as well, and if some noise will be picked up by this point it will be hugely amplified by the feedback resistor. The signal that comes from opamp output that is inverted is meant to keep the noise level at minimum because if any gain of such noise will occur at the opamp output, it will be effectively attenuated, as it is the same noise as at the virtual earth point but inverted, and that would be the effect of capacitive coupling between the guard track and earth point. If connected to ground, still the common mode noise could be amplified but not attenuated then, and if any noise will be picked up by the ground it could be easily translated to the opamp output causing errors. It is another thing if by these impedances that theory is valid but this is how mostly the russian engineers are trained.
A guarding has nothing to do with noise. It permits to avoid leakage currents due to pollution on the board. Leakage currents return to the guarding track and not to the sensitive track. If you have a voltage present between the guarding track and the track itself it will increase dramatically this leakage current. Difference of potential should be minimum. Furthermore on that board you have all combinations, you don't have the same guarding track connection for same configuration. Anyway guarding tracks are not required with such resistors values.
On one hand, it really looks like the home project of a not very skilled amateur. But on the other hand, if it does its job, the look does not really matter. What's more important is that the production of these pieces of hardware does not require the sophisticated production lines and well-trained personnel. Everyone forgot, but in the case of the real war, not a proxy conflict somewhere overseas, the high-quality professionals quickly become a very scarce resource. And you will have to do the job with the people you have right here and right now. And without skilled personnel, the advanced machinery quickly degrades. Will it be possible to reproduce the production cycle with just that? What will be the time lag before the "downgraded" production lines start producing enough lower-tier munition? So the "Russian", "Iranian", "North Korea" technologies are worth not joking about, but analysis. Because it is quite possible that, in the end, all the war participants would use something like that.
