USSR lasted officially until 1991. But the marking "Сделано в СССР" was used on new products up untill the 2000s because it took a while for the factories to reform their production process. So one could find radios, TVs, fridges that were made in the Russian Federation, but the products had written on them "Сделано в СССР". Nice video and cheers from the former Soviet Union.

I do not agree. things of 1992 were already with a hidden inscription "made in the USSR", as well as about the price. Yes, the molds were not changed until the end of the production.

The USSR existed up until 1991, and some of the soviet radios/tape recorders, etc. were continued to be manufactured for some time in post-soviet Russia. They can look the same as the Soviet ones, but the markings are different, and they don't have the price tag embossed because of market reforms. This one is late Soviet, though.

The latest Russian germanium transistors I have were made in 1992! Incredible that they were still making those that late. Good quality though, very consistent production.

There was a "CCCP" until December 1991.

Wow another great repair without schematic. Thanks Shango for showing us the huge knowledge on electronics You got.

I came here to learn something. I have stayed for the snark.

Always love to see a win like that Good Job !

FANTASTIC! You breathed life back into it.

Excellent bit of micro surgery. Love your work and the videos.

The weather has been very warm the last several days. I was outside at a forest preserve and everyone and their brother were out enjoying the warm temps. Fun video. Loved the search to fix.

The diagnosis & repair of that IF coil was your “dark side of the moon”. Awesome job man.

Awesome repair! Awesome radio and great sound!

Amazing repair there, as always. I was 13 when this radio was made in 1989! xoxo

Like watching you fix transistor radios

nice find and fix, really love watching your vids, learning alot

It looks like the construction used in a Bush radio I have from 1962. Nicely put together and easy to work on.

Awesome. Love your troubleshooting skills.

Nice troubleshooting Shango. Take care.

Well done again comrade!!!

excellent. these small victories keep me alive while a madman drives the bus. thank you sincerely.

Very satisfying repair.

They were known as a Vega Sapphire in the UK. Very sensitive with excellent selectivity too.

This was one of your best. A little microsurgery and it fires right up.

one more time VERY GOOD WORK With excellent results !! The piezokeramic filters are often bad, but in this case probably not. The lack of signal probed by the signal-tracer behind the filter may have two reasons, only my presumtions: - The attenuation of these filters can be quite high (10...20dB afair) but in combination with high if-amplification it doesn't matter, but the if-selectivity will be very high with this ! Perhaps the sensitivity of the signal-tracer was not high enough to get the signal on the output of the ceramic-filter? - These ceramic-filters need the right load-impedance to get the signal, perhaps the impedance has to be matched and without the proper load of the following stage there will be no signal-voltage... the death amp-stage with no voltage has not the proper BIAS and perhaps not the proper load-characteristic... I guess. As far as I remember the ceramic-filters have the best narrow-selectivity (it can be heared while the tuning ) and the filter-coils that are single-resonant-circuits (as opposed to bandfilters with 2 coupled resonant-circuits), have the better far-away-selectivity and a smaller damping, thats why both kinda filters are to be found. Perhaps with only coils and bandfilters only two if-stages had be done like in many cheapies, but HERE WE HAVE (...with shango's speaking^^) 3 stages and much more selectivity... With 3 stages you can get a if-amplification of about 2000 or more without AGC-damping

I have two Soviet era radios I've picked up on Ebay. One is a Sport2 that works great and the other is a Khazar-304 that I got and was dead. I fixed some really bad soldering and it started working only to die about 20minutes later. When I moved a transistor I must have broken off the lead to the base of it. I got it working again now its distorted.. go figure.. Its really a crappy radio so I may never bother getting it working any better. They are fun and different to work on. Great videos as usual! thanks for posting

Отличный ремонт. Получил удовольствие от просмотра.

Fantastic way to end the Monday here in Australia

You figure with the size of the USSR they would have to make a radio with great sensitivity. Another awesome repair view! I would send you some broken Russian electronics if I knew where to send them.

Yes, the radio has a silent background when on channel. Interesting. Nice fix!

Very good Job. Reminds me of the glue that becomes conductive on the Sony Betamax head drum hall sensors. Cheers.

Great job, great video comrade!

South Australian here. it is possible to eradicate we have had 0 cases in 12 days. hold in there

Great job on the coil repair, that must've been tedious.

Micro J-hook job..love it. Piezo filter could work with electrostatic charges from the followig transistor.

I think I too would LOVE a Russian radio. I have one of their Geiger counters. They had it going on, still do. Wow it sure does pay to trouble shoot, what a great save by the master agent 006. Happy Monday all ya all

Nice video, fixed using some microscopic fine wire surgery! You mentioned how you like those Russian transistors (the ones that look like hats), there's something else sought after that's Russian, nixie tubes! I have a few nixie tube clocks, a couple use Russian nixie tubes. These were made all the way up to the early 90's when in the U.S., they were phased out by the 70's already. The IN-18 Russian nixie tube is sought after because of the digit size and can run $60 each. They are really a good quality display tube. First airplane I heard in one of your videos in a long while although I think jet travel is going to stay at a very minimal level, other than cargo flights. I've seen pictures where dozens of aircraft are just parked with nowhere to go.

Very good! You repaired the bad IFT, and it seems the radio plays well (at least on broadcast band) This must have cost a lot when new, seems they spared nothing on the schematic (if for another model, but circuit seems a lot like yours) There also was a signed certificate from the inspection (OTK).. I also repaired a tiny IFT with an open winding from a Philips radio once, not fun..

I have such a receiver still lying somewhere. In the 80s bought. Still working. Only once did the capacitor have to be replaced.

Super!

1989 is a fatatidic date, because that's the year when the Iron Curtain fell (actually in november that year, in Berlin). The Soviet Union really started to fall apart at that point and Gorbachev launched his Glasnost policy (openness policy). So in a sense, what you have there is a small piece of history. I wouldn't be astonished if that radio was built in Eastern Germany which was still part of the Soviet Union (until november 1989) Great find!

I don't think so. East German products had a "Made in GDR" and before 1972 even "Made in Germany" which was the reason why West German products of that era often have a "Made in W. Germany" stamp.

I found a box full of these in 1992 in the UK at a small market. The plastic construction felt minimal and they were selling them for £5 each. I laughed and moved on.. I have totally regretted it ever since, especially as I have a bunch of Soviet radios now and their performance and sound quality is superb ! Just never try to work on them !

Love it!

My favorite part was when you dwelled on the super loud squealing. If we could regularly get some more of those in your videos that would be just great. Also, if possible, could you make sure the volume is maxed out at all times? THX.

That white block is definitely a ceramic filter. It has insertion loss that means that some decibels are lost for the benefit of higher selectivity.

It was still CCCP in 1989. Soviet Coup attempt occurred in 1991. I was a junior in HS at the time. Enjoy your videos here in southeast Pennsylvania.

Hi Shango, well done with this IF can! I don’t know why shortwave is quiet in your area, where I live (city of Be’er Sheva, Israel), shortwave is very alive all day long and at evenings, 60 meters up to 31 meters is very packed. Maybe the radio needs alignment to wake it up (but I guess no alignment instructions...).

Not only did shortwave seem deaf. But the longwave band was picking up a lot of AM mediumwave stations. Which it shouldn't do. The image rejection seems to be very poor on that band. Longwave in the US has only got beacons I think, and isn't used for broadcast stations.

Finally I sense of normalcy when a plane goes by and sound like it's going to crash in your filming location.

17:37 The reason why you didn't get the signal from the output of that filter is that the filter has very narrow bandwidth from 460 to 470 kHz (center frequency is 465), greatly attenuating everything outside this window. The input signal was just above or below filter's frequency.

What kind of red probes are you using and are they self piercing probes or do they just clip on the wire??

It looks that that piezo filter thing got some DC bias through the base of that transistor. Could that explain why the missing collector connection on same transistor made the filter go dead?

awesome video ( as always) but this radio bothers my OCD lol the second non speaker circle, almost looks like it wants to be 2 speaker stereo, but isn't , maybe some are??

Funny to see that there was still a market for AM only radios in 1989. If it had FM it would have been the OIRT band (somewhere in the 65-73Mhz) not compatible with the rest of the world. I still have a VEF 206 here which served as a decend world shortwave receiver until the end of the Wall.

They used large can Ge tranies right to the fall of the USSR. As a pedal builder I say thank god for the cold war and the Soviets for building Ge transistors into the 1990's. Their mini and sub mini tubes are outstanding as well. I believe the USSR fell in 1991. The part stamps aren't going to change when the regime does.

I had a similar problem on a soviet TV. The pilot transformer of the horizontal output transistor was open due to a wire corrosion near the pin. I think that the plastic had some strange reaction with the copper.
