Sarcasm aside, it would be very interesting to see how much of a mix between German and American pre war television technology this set contains. Or whether some post-war developments were incorporated as well.

And whether Philo Farnsworth was a KGB operative.

Any schematics available?:smoke:

Wow...that one went right over my head! :withstpd:.

Wow, what a treasure. Such a rare and distinctive set, and (CRT aside), in wonderful condition.

I see there is a schematic at http://www.radiomuseum.org/r/sachsen...ingrad_t2.html . That would be interesting to read, but I'm not a RM member and can't download the whole thing.

Back in the cold war days I heard that Russian TVs were in black and red, not black and white... :D

"Better dead than red" "Kill a commie for your mommy".

I am truly amazed that you pulled this purchase off. I used to work with a Russian who shipped shoes in crates back to Russia and had hurdles that were incredible, including small payoffs. You had the right people helping you and my hat is off to them and you. Good job.

Fantastic score!! A set of my people :D

Dibs when ya sell it ;)

CRT problem solved! But seriously, I appreciate your perseverance in locating and obtaining one of these rare receivers. Is there an equivalent U.S. tube from that era that might replace the Russian CRT? I know several manufacturers produced an 8" tube (8BP4) A round tube. I also know there would be many electronic issues to overcome that would change the original characteristics of the set. Just thought I'd ask.

The original CRT is magnetically deflected while the 8BP4 is electrostatic. Unfortunately, I don't think there are any U.S. made 8" round magnetically deflected CRTs

Here's the pinout. Not much to it. Just a basic triode gun.

Sigh :sigh: If only it were that easy.

I am a real stickler for originality so I'm going to head back behind the curtain and see what I can shake out. The CRT isn't exactly easy to find over there, and most Russians wont consider even talking to me as an American so it will be another up hill battle. I'm searching for replacements in Germany as well.

Here's a cool shot of the label on the CRT.

It's certainly an interesting set, as well as the story obtaining it. Hopefully you can convince one of your previous contacts to help ship a known good replacement CRT's out of the country.

Didn't those Arvin metal cabinet hospital sets use an 8" mag deflection CRT?
If I were in his shoes I'd first look for an Arvin, and or radar CRTs...There may have been an American military or radar application 8" CRT that could be used in the original's place. On the radar and mill tubes you want to bone up on phosphor types...IIRC there are some non-p4 types that will look decent, and others that will be terrible.

Right you are. I should have said no all glass 8" round CRTs. The 8AP4 is indeed magnetically deflected but has a metal cone. Also pretty darn scarce.

John - Is it your intention to eventually restore this set to operational?

Not immediately. This set is very original and quite unique in this country. It's on my "it doesn't have to work" list. Someday when my kids move out and I don't have anything to do I may start restoring sets on that list. For now I'm content with some sets that work and some sets that don't.
