> These are mostly 14-pin "flat pack" integrated circuits in metal packages, unlike contemporary American integrated circuits which were usually packaged in black epoxy. There are also some 16-pin integrated circuits, encased in pink plastic.
It's worth pointing out that flatpacks (both ceramic and EP) were and probably still are a mainstay of military and aero electronics. These were never used in consumer electronics. Apart from microprocessors and EEPROMs, consumer electronics never really used ceramic or hermetic metal packages for cost reasons. Perhaps the most common components would be TO-3 power transistors and small metal can transistors before TO-92 and similar packages obsoleted all of those.
> Many of the components in the power supply look different from American components. While American resistors are usually labeled with colored bands, the Russian resistors are green cylinders with their values printed on them.
High grade or high precision resistors usually had their value printed on them, though. Meanwhile, only larger SMD resistors have markings today (I think they stop applying them below 0604 imperial).

Semiconductor packages were all over the place in the past; I've seen cube-ish moulded diodes, resistors and capacitors in European stuff.
Overall this thing looks a lot like something from the mid 60s, not so much mid 80s. In that case, American stuff from the same period looks pretty similar, quite possibly due to copious copying by the Russians.

On a related note, I really like IEC/ISO schematics for this reason, because we have a graphical language to describe logic and this means logic devices appear as a composition of symbols which explain the function of the gate to anyone who knows this language. On American schematics only the most basic gates (AND, OR, NOT, ...) have symbols, everything more complicated than that is generally drawn as a box with the part number ('193) in it and the pins just labelled with their abbreviations.
Wrt. to flatpaks it is somewhat interesting to note, that very often when there is some kind of ASIC (think alarm clock or calculator or even “PDP-11 on a chip”) in 80's soviet consumer electronics it is packaged in metal/ceramic hermetic flatpack with legs bent and THT soldered.
Ceramic side-brazed DIPs look very futuristic to me for some reason, especially when the carrying substrate is light colored. Plastic packaging is pretty dull in comparison.
