I guess you can just do image search for [принципиальная электрическая схема].

A lot of western instrumentation and test equipment used to come with full circuit diagrams and assembly info. The understanding was that your HP spectrum analyser or Tektronix scope cost so much money that if it broke then you would have it repaired, and to do the repair you need the circuit diagram.

  Not any more, of course. It also deserves to be mentioned that lots of higher-end equipment used a lot of custom parts, and not always out of necessity (like custom µPs in HP multimeters, or stuffing solenoid drivers into unrelated hybrids ... and of course anything handling higher frequencies almost always used some custom chips or selected transistors hidden behind opaque part numbers). Sometimes there are still schematics, Agisight still does it e.g. for low-end power supplies.

  Yes, similar information used to be made available for Western electronics. In addition to engineering equipment, consumer electronics such as TVs and radios, and even computers had full schematics at one point. As an example, can see hardware schematics in the Apple II Reference Manual found here: http://www.applelogic.org/UserManuals.html http://www.applelogic.org/UserManuals.html I'm mostly interested in the Soviet material as I'm assuming that because it was a legal requirement the types of documented designs will be more broad, but if you know of an archive of old Western schematics also, I would be interested in taking a look.

At least for home computers, much of the schematics and manuals have been preserved through the dark ages of the 90's by home computer enthusiasts and put on the internet thankfully. For instance (not Soviet, but East German): here are a few links to manuals and schematics for the East German KC85 computers: http://floooh.github.io/virtualkc/p060_links.html http://floooh.github.io/virtualkc/p060_links.html But this sort of detailed schematics 'coming in the box' was also common for Western home computers, and it's all preserved. The same for reference manuals of CPUs, and especially support chips. Without these, writing emulators would be much, much harder.

There are websites created by enthusiasts of different categories of equipment: audio amplifiers, radio receivers, home computers, synthesizers. Easy to google "device_name схема".
