Such an odd thing. Very similar circuitry to a classic needle ioniser, but uses a long linear emitter wire instead. The circuitry has a nice soviet feel to it, with very chunky Russian components that seem a bit retro compared to UK ionisers from the same era.
Ionisers are blighted by a history of bad marketing that makes bold claims of being "air vitamins", and implies that the units will resolve many health conditions. In reality, the main function of ionisers is to put a charge of electrons into the air like static electricity, causing airborne contaminants to precipitate to grounded surfaces like walls and floors.
The classic desktop ioniser makes a huge mess due to the contaminants in the air settling in its vicinity. Many people stop using them because of the apparent mess they make, without realising that it's there because the unit is doing its job.
They are best suited to smaller areas with low air throughput, are silent and use such a low amount of power that they effectively cost nothing to run.
I'd guess one of the main advantages of the Ryazan 101 ioniser is that it's long emitter is far enough away from walls to precipitate that dust out in a more subtle manner.
Incidentally, the ioniser PCB of my own that I showed is now a free PCB at JLCPCB (Not a sponsor.) Note that it is only suitable for 220-240V countries though.

It seems appropriate to mention it here since it was inspired by the Chizevsky ioniser and can be used as the power supply for the "Russian Nuclear Corporation" ozone generator. (Produces very low levels of indoor ozone that emulate natural outdoor levels.)

    "wondering what that is"
    a radio receiver set

    I'm sure this will give you cancer.

    But why the piece of string across the ceiling? What function does it have?

  4. Avataaar/Circle Created with python_avatars 100 Music Playlists says:

    how can you tell if the air around you is ionized or not?

    Typical that it is Red hehehehe.
    What you think is a "strange" neon part is a KGB camera with audio capabilities and part of the high power output is a modulated radio signal 😉

    i got a 51 led flashlight wich keeps flickering by itself and turning on and off even with fresh batteries maybe it could be interesting for you to look at

    i love looking at old electronics

    These capacitors are junk. They look cool, but they leak badly even when new/new old stock. Some eBay sellers sell them as super audiophile mil spec caps. Buyer beware!

    Heyyy, no such thing as a thousand million, that's a billion 😛

    That thing in the manual illustration is a tube radio. Have a very similar looking in my log cabin, mine is called Ural, but there were many brands like Rigonda, VEF, Chayka etc. Pretty amazing that after all those years in the damp environment it still works fine – the only thing I had to replace is a turntable needle.

    A very good Thursday morning to you all

    For correct pronunciation use text to speech on the translator 😅 it sounds more like rezan not riazan 🙈

    Thats a really nice looking old board and schematic!
