That's exactly what I thought.

That is the distinction! A paper capacitor can be everlasting if it is sealed absolutely hermetically. The white porcelain tubes with the metal caps on their ends, and the grey tubular metal cans, are the paper-type capacitors that don't need to be replaced!

I don't see any carbon comp resistors, anywhere, either.
All WWs? |

The green rods are carbon film resistors.

vts1134, thre's no any news from you. Are you still interested in getting a 23LK1B for your Leningrad television?
This CRT is a dud but I got in contact with a fellow from a CRT rebuild shop and told him your wishes about originality. He's willing to save the original appearance of the CRT as much as possible while rebuilding: to keep the original gun by replacing only the cathode, to provide and guarantee a good lifetime without aluminizing, and so on. But then I lost contact with you; you haven't responded to a number of my emails. We all guess that the rebuild shop won't last long...

Rather obvious from the family photos that filthy, Godless Commies & Murricans were/are more alike than 1st imagined. That family pic could have easily been Americans-I've seen dozens thru the years. The Americans qould have likely been wearing big hats & holding rifles, though. Always suspected Russians & Americans would have generally been fast friends if the language barrier could have been overcome, & our 2 idiot governments had been gotten outta the way...

Totally agree!
The reverse example for me. Apart from the background, I could decide that there're some normal Russian builders from the 1930s having their lunch We are pretty similar by nature, physically and even mentally, and our nations have a lot to share! Let's be friends, do deals, share experiences, and leave the politicians to play their own games! Back to the CRT. I should explain why I'm so eager about rebuilding. I have a number of exhausted picture tubes on hands, beside the one intended to vts1134. Visiting the rebuild shop requires two pretty long drives (about 150 miles each way), to bring the tubes there and back, accordingly. Thus I move and move my rebuilding plans, waiting for John's decision and wondering how soon the shop may go out of business...

Sorry for not replying Gleb. I have been extremely busy and my TV collecting has taken a back seat currently. I've replied to your email.

Nothing changes, still not replying. I'm gonna make a rebuilding trip in early March, whether or not I take your picture tube.

Here is another video of a performing Leningrad-T2:

I believe he uses a modulator feeding it a composite signal.

Thanks, but I'm still wondering what kind of composite signal.

I was looking over the schematic when I noticed that it has only 2 stages of video IF but 3 stages of audio IF. Is that due to using the TV sound section for the FM radio?
With only 2 video IF stages, I don't think this TV Was intended for fringe areas. |

Most likely, the idea was in the use of either single or "overcoupled" IF coils / transformers, along with the high-gain 2 stage video amplifier. As a Leningrad's owner, I can't say that the TV's sensitivity is noticeably worse than others of the time, at least the ones with integral tuners. Later models with separate turret-style tuners do some better, of course.
