(LFS/WTB) Universal Oscilloscope s1-85/c1-85 Technical Handbook Part 2/ЧАСТЬI 2?

[Chris56000]

Hi!

Has anybody got a copy of, or knows where I can obtain, The Technical Handbook Part 2 / ЧАСТЬI 2 for the Soviet-made C1-85 Oscilloscope please?

I've found a copy of Part 1 / ЧАСТЬI 1 but this stops at page 237, halfway through the PCB layout drawings !

Presumably Part 2 / ЧАСТЬI 2 contains the rest of the PCB layout diagrams, the Parts List and the Circuit Diagrams !

It seems that everything is what is: (

Maybe worth trying to contact this seller:

Not sure how complete their part 2 (часть 2), but for < $9 this might be very good option. It's possible to write text message to his phone number I believe.

Hi!

I've sent a request to the seller given in the link above!

The C85.zip file in the reply to my query was 237 page Part 1 only – I'd already found a copy of that!

Sorry, seller claimed that they have part 2 as well, so I thought that there is a chance they really have full schematics.

Hi!

I found a basic schematic, but only the same one as Member "Megavolt" provided, but it's basically little more than a "module interconnection diagram" , and there are no component values whatsoever on it! – if part 2 of the C1-103 book is anything to go on – the C1-85 book part 2 not only has the basic overall circuit diagram I did find, but also details the full Component Parts Lists and Circuit Information for all the Internal Modules, plus the "overall circuit diagram", and details of Signal Interconnections (in Cyrillic of course!) are also in Part 2 / часть 2, so you really DO need both books for these very complex Soviet Oscilloscope designs!

What I can't understand is, presumably the incomplete diagrams I referred to came from  Part 2/ЧАСТЬI 2 - it's not in the Part 1/ЧАСТЬI 1 book, so why didn't whoever got it scan and upload the rest of the book?
