Translating russian CRT datasheet

[Dajgoro]

Any Russian speaking folks over here?

I have datasheets of Russian tubes that i bought from ebay, one is for a vfd display, and i managed to figure that one out, but i still didn't manage to get the following one(cheap soviet crt):

I managed to translate the following pins:
1,14 podogrevatelb ?, that would be heating
2 katod, cathode
3 modul?tor ??? modulator
4 oteutetvut ??? missing
5 anod perb?? First anode
6 ne podkl??? not connected
7 ,8 plastina signalvna? y1/2 , probably y axis
9 anod vtoro?, anode something?
10,11 plastina vremenna? x1/2 probably x axis
12 zkran ?, screen
13 ne podkl??? not connected

Further reading of the text just gives mi a headache, since Russian is only vaguely similar to Croatian.
And how this contraption even works, i have 6.3V, 250V and 2000V but how to make it work.
I was hoping to make a terminal like device out of it.

Thanks for any help!

See if the tube type number cross-references to any German, UK or USA types. A lot of Soviet-era tubes were direct copies of standard types produced in the free world. You may get lucky and find an English or German language data sheet.

Wow. Nice puzzle!

This is almost the word "modulator," which is a plausible name for the grid intended to control brightness of the trace.

The diagram on the second page is quite revealing, because it symbolically shows 11 connections and their respective pin connections. ( I wonder why the adjacent chart lists 14 connections?!) Pins 7 & 8 and pins 10 & 11 are the pairs of plates for X and Y deflection (or Y and X; I don't know which is which). Of pins 5, 9 and 12, one will be a focus electrode -- probably 5. The other two I think are accelerator electrodes.

You could make a vector-scan device like a Vectrex !! viewtopic.php?f=2&t=2325&start=16 THAT would be a lot of fun to play with!

Your guess sounds about right. The voltages suggest electrostatic focus and deflection, so this CRT most likely was intended for use in an oscilloscope or similar instrument.

I was thinking about building a device that would only contain the crt tube, and some pentodes(for controlling the tube), so i would get an device that would have x,y and brightness input, and then make a small pcb with a mcu for the terminal, or any other pcb for any other use.

So my question is where do i connect the 2KV, 250V, and do i need negative voltages for the x,y axis deflection plates, and what voltages would suit for deflecting? Also how to control the focus? I would really need a crt cookbook.

You can use Google Translate. If you don't know where to find it, just Google it.

As far as getting the Russian alphabet into your keyboard, you might want to google that too. You might want to study their alphabet a little bit as well.

I know Serbian Cyrillic, but the Russian one has some additional characters that we don't use over here. I could type some parts in Google translate, but dunno what to do with some characters, and also who knows what would Google make of it. I could type blind Цѕрилиц(Cyrillic). Anyway, any suggestions how to make it work?

One approach would be to get a hold of an oscilloscope schematic (or, better yet, two or three) and see how these CRTs are typically treated. To get the ball rolling I have a pdf file I can send you; it's a Hameg oscilloscope Owners Manual / Service Manual which includes a schematic and written descriptions of the various circuits (which in this case are solid-state except for the CRT itself). PM me.

Stepping back a bit, though, perhaps this particular CRT you've acquired isn't a good candidate in terms of the time and effort you'd need to invest. As an alternative you might consider

• getting another CRT that has better documentation available (ie, not in Russisan)
• acquiring a second-hand oscilloscope (which might be very inexpensive, yet would have the CRT, enclosure and circuitry you need)
• forget CRTs and see if you can find a flat screen (LCD) computer display that's been discarded. Sometimes they can be easily repaired. (The display I'm using right now is a refugee from the recycle bin; 1280 x 1024, lovely big screen, and all it needed was a new electrolytic in the SMPS.

I am not sure how a Russian would transcribe it, but it would be more or less:
1,14 "Podogrevatel" (the small "b" at the end is not a "b" letter ) - Heater
3 "Modulator"
4 "Otsutstvujet" ??? Need to find my PL-RUS dictionary
5 "Anod pervyj" - First anode
6 "Ne podkluchen" - Not connected
7,8 "Plastina signalnaja" - ok, this would be Y axis
9 "Anod vtoroj" Second anode
10,11 "Plastina vremennaja" - this would be X axis ("vremja" is "time")
12 "Ekran" Shield (?) (at least this is what "ekran" means in Polish)
13 "Ne podkluchen" Not connected

My first electronic playground toy was a Russian "Junnyj Elektronik"

[edit] - where I put "j" this would be English "y" - it is the "longer i"

Thanks for helping! Time in Croatian is vrijeme, screen is ekran as well, but i didn't translate that Cyrillic well enough . I bought the screen to have some fun with it, lcd-s ain't so fun .
Ill try to find a schematic of a crt clock.

Looking at the tv to scope projects, i found out that using an LM1881 ic an tv to scope circuit can be built with very few components. What about vga, how hard would it be to display it?
It would be nice to have kinda of an universal monitor.

otsutsvujet is 'missing' or 'not present' according to a native speaking friend.

Thanks!

Thanks!!!

I think ill use EF80, and maybe some ECC81/82/83.
