Actually, some russians (like me) watch foreign stuff repair videos with the same interest. Back in the 80-s japanese electronics in Soviet Union used to look like sonething from another planet :)
I'm guessing that this Soviet stuff would have a lot more hours on it than radios like this one that were in the US. Do you think that is generally true?
+tarstarkusz yes for sure. As I remember people used to listen to these radios up to mid 2000's. Some older russians don't realise that electronics can become obsolete and must be trashed out after ten years. They were brought up that all the things are made for ages, and the most of 60-70's stuff really was. Back then everything cost a lot of money and the DIY was way too popular (old good times...) Soviet engineers tried to understand how to make a domestic electronics the same way as abroad, but they didn't get it. Something went wrong in the 80's, the quality dropped, we falled behind the foreign technologies and in 1991 the Soviet Union crashed :( Funny thing: there were so much obsolete parts on the TV factories, so some of them were assembling a full tube B/W sets up to 1993! And tube/solid state combo colour sets up to the same period. That's the negative side of Soviet politics, it wasn't engineers' but goverment's idea
+Олег Семенов Thanks. I was also thinking that the radio was likely to be more popular in the Soviet Union than outside and that these (small transistor radios) would be more likely to have been bought by adults in the SU than in the West, largely because of cost and availability. But I did notice some Boom Boxes on EBAY from the Soviet era. It's a shame because there was a pretty much total blackout in the US when the USSR still existed. I was 20 when the Berlin Wall fell and we didn't know anything about the Soviet peoples. To some extent that still exists, not to mention the language barrier.
+tarstarkusz Back then the most people in Soviet Union didn't need more complicated devices than radio and TV. There was everything that everybody needed - news, weather broadcast, educational programs, music, drama and various art shows. But all that was controlled by government, and mostly nobody knew what happens abroad. I heard a lot about listening to Voice of America, BBC and FRG news, it was not so easy - the foreign radio was jammed by secret services. Anyway, many people build directed antennas, modified regular radios and got a good result. And not many of them realized what was actually happening all over the world. The main difference between soviets and americans - USSR wasn't built on self-regulating mechanisms, everything was controlled by goverment. So today everything has changed but people still believe the government must to organize their lives when it doesn't any more. People are brought ip to be trustful and mostly irresponsible to themselves. It's a total crap..
5:20 - "Сделано в СССР" - "Made in USSR" - text on the back. It's funny how those radios are more useful in America than here in Russia, because there are almost no AM stations left.
It's time to modify soviet SW radios and listen to SSB hams. The only really cool fun that could be easily done with that. Building AM transmitters by ourselves is kinda complicated and illegal
+wrnchhead I'm from Moscow. During last ten years LW and AM bands were slowly dying, now there's absolutely nothing in the LW and a couple of weird weak stations in the AM. Far from the city it's more alive, but all the stations are too far away from the capital. SW bands feel better - it's possible to receive Europe and Asia, but not in the cityside - there's a hack of a lot of noise
@@wrnchhead76 Sadly, that's mostly true. I wouldn't say AM is dead, but it's definitely a shell of what it once was. Here in the Minneapolis/St.Paul Minnesota area, we have a few AM stations that broadcast music. We have a 60s-70s oldies station that broadcasts in C-QUAM AM-Stereo, 740 WDGY. Another staion "Album Rock 540" WXYG also broadcasts in AM-Stereo, I'm right on their fringe though so usually only my better radios can receive them with decent enough quality. Sad story: a little less than a year ago, we lost an big band/adult standards station, AM 1220 KLBB (that I have an aircheck of on my channel), the land the transmitter was sitting on was worth more than the station itself. So with the land sold (for senior housing I believe), the station was shut down and dismantled...
The model in USSR wasn't "buy a new one every year", it was more like "buy it, keep it, so the factory can build radios for the army instead of radios for you".
@@xavierrajda933 Radios where never guaranteed necessities. Like anywhere else they are luxury items especially 60 years ago. I would rather a home, a good job and food to eat. The necessities where guaranteed after the war.

You have convinced me to go get the old Jade Transistor radio that I purchased at Smith's Rexal Drug store in Lemmon, SD back in 1967 using money I earned working on my uncle's farm cutting and bucking hay (5 bucks a day!). Thank God mom had the presence of mind to put it away when I married my good wife back in 1969, and returned it to me a few years ago whilst we sat at her kitchen table playing cards. She will be 93 next month and is loving life in the Nursing Home where he was admitted about 3 months ago (she still has a valid drivers license but has enough common sense not to drive any more, in fact I sold her car for her about 5 years ago.) Yep I am going to go in the back room and get that little radio and open her up!
That radio has some pretty good DX qualities at night. It's a long way between the RF-saturated Los Angeles Basin and Window Rock on the Navajo Nation in Arizona! It *STILL* sounds good with all those bridged electrolytics!
As a relatively newcomer to fixing vintage transistor radios, I found this video very fascinating as I have yet to come across a bad transformer. All your vids are great!!
Another great video Shango! I purchased a SOKOL 403 (Same as one of yours) Last year, complete in box with charger, instructions etc... Needed a few caps replacing and a general service. Out of all my British and European "Personal" sets its my favorite. The sensitivity is great, and the sound quality amazing. Like you, ive started collecting Soviet portable radios. Perfect here in the UK as we still have loads of stations on AM, and it picks up European stations with ease. As always, a fab repair video. As an 19 year old vintage TV and Radio restorer, your videos taught me a lot when starting out in diagnostic fault finding, not just chucking new capacitors at things! :)
I’m a big fan of the “hack repair”! I love to see it every time! Takes knowledge to perform it right! Thanks! Good fix. Saved that radio from the trash.
Another interesting and very educational video. "If it ain't broke, don't fix it". I've tried to live by that philosophy and it has served me well. Thanks again for sharing and keep up the great videos. Take care!
I love the fact that you include mistakes in the videos so I can learn from them! You always preach less is better with old electronics, and this is why. Sorry the transformer is gone though. Keep em coming Shango, If you set up a Patreon I'd kick in. I always learn something new from your videos. Peace!

Great job now I have learned to repair a transformer thank you for posting this video but you never give up and can fix it just look for another transformer all the best
Damn it... you know , when I was watching the video and you mentioned that you're going to remove the transformer in order to put back the laminations, my first thought was "nooo, for god's sake, don't touch it! It's pins will break off... just put back them with a tweezer in place and fix with a drop of epoxy or something". So I was happy, when you decided to put back them in front of the camera and found it very impressing how much the sound was improved after even the first inserted lamitation, which closed the magnetic circle. And then it just happened as I thought... I remember as a child (like 10-12) when I first got a soldering iron in my hands, I started learning soldering by disassembling old stuff like this, usually found on the street, or anyway already trashed. What I wanna say is that these early circuit boards are so low in quality, that even the smallest amount of heat causes that it will instantly drop off the copper traces when you start to de-solder anything on them. But you might know this as well I suppose :) Anyway now you've documented very well the Nr.1 rule of engineering: if it works, let it alone, don't screw around! :)
Excellent! I was never aware of the quality of the Russian radios in the 1960s. I assumed the old German radios were well made and the older Japanese radios such as the Panasonic and Sonys. It is good to learn this.
What a nice little radio. Glad you could fix the transformer problem...and I love that Oldies station, too bad we don't have stations like this in Germany. Neither on AM or FM...
I didn’t know there was such a thing as a gear reduction Polyvaricon, man where where those when I was building my small QRP projects. Great video. Joel, N6ALT
Well, you can't win them all. I screwed up on a really nice tascam audio cassette deck and am now making a part from scratch. But at least, as with the radio it will play. I should consider myself lucky the deck will play well for the owner again because I broke the same rule - too much force on something delicate I didn't see all of yet...and I knew better, and it will learn me. Neat how you put the transformer together while it was running!
Awesome soviet germanium transistors, built like tanks. The person you got it from said it did not work which meant they tried to make it work with the little sheet metal 'e's' floating around shorting everything out. I agree on not removing the transformer and would have shellac the leaves in place. And replacing the electrolytic capacitors, I would have done that. Also would have taken the volume/switch out to repair it. They can be popped open and usually what is wrong is both the contact end is dirty and also lost some of its shape. Repaired a lot of those before. Some leather treatment (like "mink oil") so it can last another 50 plus years. Fun stuff!
We've all went against our gut at some point with detrimental results. Atleast I learned something about those micro transformers and what to look out for. Your talent got it working again and that's a win in my book!
What a nice little radio, love the geared tuning. Those flat transistors are really unusual, like alien craft from space lol. Never mind about the transformer, it works :-D
I guess that you could have wound a new secondary over the top of all the other windings, it would probably work, a bit lower efficiency though. Radio seem pretty good, no nasty distortion that sometimes happens.
Shango, the 'gimmick' is not a gimmick. It is in between the two audio post-detector transistors T4, T5. It's probably that 3300pf and is missing at this point. Any other part in the area (the resistors) would be vital, so it's probably that cap. I would have simply put a drop of superglue or model cement onto the re-assembled transformer. Unsoldering those things risks undoing those tiny and brittle internal connections. I'd also mention that when I was in my early teens, I was playing around with, and fixing lots of these abandoned radios for myself, and had already ammassed a large collection of spare parts: volume-pots, tuning caps, loops, etc. It would have been easy for me to replace that bad volume control with something that would fit. Just sayin'.
I have an old GE all Transistor radio! It used to work and now it’s so quieter I can’t hear it anymore the hiss from the amp is still there but I hear muffled sound. Any suggestions?
La Crosse WI EAS The electrolytic may have dried up with time. Sounds like a coupling electrolytic cap is open that passes the signal from the detector stage into the audio stage. A signal tracer may help locate where you are losing the signal
I recently got an Алмаз (Almaz) transistor radio in the mail. I'm surprised how easy it was to find a schematic for it considering its rarity. I like these spaceship transistors, I can't say I've seen a case where one was bad; then again I haven't seen many.
Good video, the outcome was good, I thought you may have come up with a solution for the issue with occurred and you do, good work here again like all your videos. Thanks.
This example seems to be manufactured somewhere around July 1969 as most components have that marking. The volume control reistor is from 1971 but it has also retail price mark on it so likely was changed later.
The reason they were built to last was because it took years to get one! Maybe not so much radios, but definitely big ticket items like cars and appliances.
That was wonderful watching the E cores getting replaced. When the magnetic circuit was restored with first a single core and then the second gave 70% of the output, so it seemed, maybe the automatic gain control on the mic gave a false impression. Where else?
Pentium 100 Mhz is right: I have another 'coat-pocket' Soviet radio, 'ALMAZ'. The thing is inscribed on the top of the case "On the birthday of Misha, from the family, 20th April 1970". Obviously it was cherished & well used. Used well enough for the case to have wear patterns as well as the volume control wheel. It only needed a wire from the MW coil on the ferrite rod re-soldering. It doesn't sound like complete garbage.
Hey i got a question do you mabye know how to build in fm in to a radio
5 ปีที่แล้ว
What a great video AND moral lesson ! My old man once told me if you eff with something long enough it WILL be effed up. But replacing that transformer was the first for me. Finding a schematic? absolutely phenomenal. Question: how come the radio has mostly English words coming out? Shouldn't they be Russki? Dos vidanya Shango
KNX news radio 1070... always blast through everytime.... amazing how that 50000 watt Signal is everywhere at night....even here in my areas of the Pacific
Have bought a couple of "Selga" branded USSR made radios. One of them works OK, but has the same issue as this one, a worn out volume control. I've had a bit of luck shimming the shaft for the volume to tighten up the carbon track contact, but still not perfect. Other radio was a $.99 eBay basket case from the Ukraine, that didn't work, and had what looked like some soviet era (make due) repairs to it. Once fixed up, it really is a solid performer. Great audio, great sensitivity, and low noise.
The volume pot wheel is dated May 1971. What about dates on the transistors and the electrolytic capacitors. I have an ALMAZ that's about three years older if the mix of component dates is reliable. The case is inscribed " To Misha from the family 20th April 1970". Obviously not a throwaway item. The thing has been so well used that the knurling on the volume wheel has worn off & the slot in the case it protrudes through has bevelled edges from finger wear. All that I did was to re-connect a wire from the ferrite bar antenna to the circuit board. The oscillator was still running, but it was silent. I haven't touched the capacitors. No need to screw around with something that isn't yet completely broken. The only Soviet radio that really gave me trouble was a Selga 404. I think it was the first set to have silicon transistors in the converter & IF strip. The Selga had one of the MP41 o/p pair defective, bad electrolytics and a corroded wire on a IF transformer due to excess flux from assembly. The Soviet small radios generally had decent sound quality for their size The Selga had a defective speaker as well. The earphone socket was a unique size, maybe 3mm.
Learning about circuits you have to treat all shotrs what caused the failure I'm finding out first hand that Changing capacitors doesn't always solve the issue I'm learning from your videos I learned I have to find out what the culprit is you teach me knowledge and wisdom
I'm surprised to see that this uses a regular 9 volt battery that you can just buy at the store. What surprises me even more than that is that it uses the same AM frequency band that we use. Why that surprises me is because, especially back when Stalin was ruling, there was a major focus on preventing citizens from being exposed to anti Soviet influences. Yes this radio was made around the time of détente, but it still it strikes me as strange that it would use the regular AM band instead of a different range of frequencies. AM signals can travel pretty far, and I would bet my bottom dollar that there were border blaster stations broadcasting anti Soviet messages.
I bet an Eagle LT44 would have worked as a replacement Audio Driver Transformer in this set.I notice you get quite a big Ferrite slab for the Aerial in these compared to western versions and I guess that helps the receiver sensitivity.Interesting that you could (just about) receive a station that was intended for Native American listeners.I wonder if there are many of these people left.
Ya can't win 'em all my friend, at least it didn't end in World Destruction :D I've got a similar dilemma with an old suitcase record player at the moment, audio output transformer is open on the primary, unwound and typically it's right at the first 3 turns of the thing... Unsure whether to bother trying to rewind it or just source a replacement. Think I'll replace it but keep the bits for when I know if the valves etc are any good maybe rewind it then. Interesting to see you post a vid with a transformer issue though. Good argument for leaving things well enough alone too.
Great performer! I’m wondering if that particular model was ever imported into the UK. Technical and Optical Equipment Limited, used to specialise in Russian gear, in the UK.
I think the tranceformer is better then what you Had in there. Atleast you dont have to Worry sbout those little e tranceformer cores Falling out. I think you did an awsome job At fixing it. I never haf to replace anything In transister Radios Except the Speaker or Tje 9 volt battery snap.

Shango066, as ever your repair Is a máster piece, thank you for sharing this awesome vid.
Много станций ловит радио на длинных и средних волнах в Америке, а вот в России уже давно нет приёма станции на этих диапазонах ! :(
Ага, очень жаль что у нас таки прикончили СВ и КВ
В Москве и области вроде есть что-то, частное или религиозное, т.к. эти диапазоны значительно дешевле, чем FM.
Well, you can't win them all. I screwed up on a really nice tascam audio cassette deck and am now making a part from scratch. But at least, as with the radio it will play. I should consider myself lucky the deck will play well for the owner again because I broke the same rule - too much force on something delicate I didn't see all of yet...and I knew better, and it will learn me. Neat how you put the transformer together while it was running!
Right on! If you are afraid of damaging something further, do not become a technician.
Awesome soviet germanium transistors, built like tanks. The person you got it from said it did not work which meant they tried to make it work with the little sheet metal 'e's' floating around shorting everything out.
I agree on not removing the transformer and would have shellac the leaves in place. And replacing the electrolytic capacitors, I would have done that. Also would have taken the volume/switch out to repair it. They can be popped open and usually what is wrong is both the contact end is dirty and also lost some of its shape. Repaired a lot of those before. Some leather treatment (like "mink oil") so it can last another 50 plus years. Fun stuff!
I could hear the coupling getting better every time you dropped an e core in.
We've all went against our gut at some point with detrimental results. Atleast I learned something about those micro transformers and what to look out for. Your talent got it working again and that's a win in my book!
What a nice little radio, love the geared tuning.
Those flat transistors are really unusual, like alien craft from space lol.
Never mind about the transformer, it works :-D

sweet sounding audio. great radio...
Wow! Very nice Radio 😊👌👆
Almost got caught in that 101 mess. Great video
I love old commie tech. Usually simpeler but usually built really well & cheap at the same time. Their is a real interesting design to such stuff.
Cheap duplication of Western technology, but from a decade earlier
Furries tryina praise dem commies, yeah this checks out.
@@JohnSmith-eo5sp you was injured on cold war?
It sounds good with that replacement transformer. When you hear Rush Limbaugh’s voice,reassemble it and pack it up!!! You’ve done a good job. !!!
great job , makes me feel old though because I was born in 64 lol
Well done, Comrade!!!!!!
That is why I Tend to J hook in components most of the time. Don’t want to break Stuff in the process of trying to “fix it right”
I guess that you could have wound a new secondary over the top of all the other windings, it would probably work, a bit lower efficiency though.
Radio seem pretty good, no nasty distortion that sometimes happens.
Shango, the 'gimmick' is not a gimmick. It is in between the two audio post-detector transistors T4, T5. It's probably that 3300pf and is missing at this point. Any other part in the area (the resistors) would be vital, so it's probably that cap. I would have simply put a drop of superglue or model cement onto the re-assembled transformer. Unsoldering those things risks undoing those tiny and brittle internal connections. I'd also mention that when I was in my early teens, I was playing around with, and fixing lots of these abandoned radios for myself, and had already ammassed a large collection of spare parts: volume-pots, tuning caps, loops, etc. It would have been easy for me to replace that bad volume control with something that would fit. Just sayin'.
Was hoping you would insertransformer "Es" to hear induction increase!
Wonderful!
I have an old GE all Transistor radio! It used to work and now it’s so quieter I can’t hear it anymore the hiss from the amp is still there but I hear muffled sound. Any suggestions?
La Crosse WI EAS The electrolytic may have dried up with time. Sounds like a coupling electrolytic cap is open that passes the signal from the detector stage into the audio stage. A signal tracer may help locate where you are losing the signal
how interesting station gear -like fine tunning,amazing soviet radio
find better transformer,now the sound is much worse
OmgI love it when you talk backwards it makes me laugh so hard😂😂
I recently got an Алмаз (Almaz) transistor radio in the mail. I'm surprised how easy it was to find a schematic for it considering its rarity. I like these spaceship transistors, I can't say I've seen a case where one was bad; then again I haven't seen many.
Those core laminations on that speaker are sending my OCD into overdrive.
Good video, the outcome was good, I thought you may have come up with a solution for the issue with occurred and you do, good work here again like all your videos. Thanks.
Btw "С" is for middle-waves, and "Д" for long-waves
Here in Russia, unfortunately, we have no middle and long wave radios nowadays
В Петербурге вроде ещё вещает пару станций на СВ одна из них Радиогазета слово.
Is that what the 'A' on the back of the radio is for, a port for a long wave aerial lead?
Love your sarcasm, especially the self-deprecating stuff. 😂
Push-pull class A?? How else does it work with one driver removed? Love that reduction gearing.
This example seems to be manufactured somewhere around July 1969 as most components have that marking. The volume control reistor is from 1971 but it has also retail price mark on it so likely was changed later.
It has an ear fone jack, I wonder how it sounds with ear buds? Clear or muffled? I think ear buds in those days were of the crystal variety?
OMG Shango good video
any how you need to make a compilation video of all the span phone calls!!!
Beautiful! Soviet stuff was built to last, even survive the ever looming nuclear war I guess. Oh, those were the days.
The reason they were built to last was because it took years to get one! Maybe not so much radios, but definitely big ticket items like cars and appliances.
That was wonderful watching the E cores getting replaced. When the magnetic circuit was restored with first a single core and then the second gave 70% of the output, so it seemed, maybe the automatic gain control on the mic gave a false impression. Where else?
у меня тоже такой был раньше! я в его корпусе собрал фм мыльницу из китайской комплектухи
6:25 , , , how you can do that every time without bursting out in laughter like I do when I watch your video!
Pentium 100 Mhz is right:
I have another 'coat-pocket' Soviet radio, 'ALMAZ'. The thing is inscribed on the top of the case "On the birthday of Misha, from the family, 20th April 1970".
Obviously it was cherished & well used. Used well enough for the case to have wear patterns as well as the volume control wheel. It only needed a wire from the MW coil on the ferrite rod re-soldering.
It doesn't sound like complete garbage.
very clear sound.... good
Interesting to see how the Russian's did things!! The old radio seems sensitive enough and sounds good enough for what it is, and when it was made !!
It seems like there was one large main manufacturer of speakers there in that time.
Hey i got a question do you mabye know how to build in fm in to a radio
What a great video AND moral lesson ! My old man once told me if you eff with something long enough it WILL be effed up.
But replacing that transformer was the first for me.
Finding a schematic? absolutely phenomenal.
Question: how come the radio has mostly English words coming out? Shouldn't they be Russki?
Dos vidanya Shango
How come pulling the output transistors one at a time seemed to have no effect?
The audio output is in push-pull and one missing (or bad) transistor distorts the sound.
KNX news radio 1070... always blast through everytime.... amazing how that 50000 watt Signal is everywhere at night....even here in my areas of the Pacific
Have bought a couple of "Selga" branded USSR made radios. One of them works OK, but has the same issue as this one, a worn out volume control. I've had a bit of luck shimming the shaft for the volume to tighten up the carbon track contact, but still not perfect.
Other radio was a $.99 eBay basket case from the Ukraine, that didn't work, and had what looked like some soviet era (make due) repairs to it. Once fixed up, it really is a solid performer. Great audio, great sensitivity, and low noise.
The volume pot wheel is dated May 1971. What about dates on the transistors and the electrolytic capacitors.
I have an ALMAZ that's about three years older if the mix of component dates is reliable.
The case is inscribed " To Misha from the family 20th April 1970". Obviously not a throwaway item. The thing has been so well used that the knurling on the volume wheel has worn off & the slot in the case it protrudes through has bevelled edges from finger wear.
All that I did was to re-connect a wire from the ferrite bar antenna to the circuit board. The oscillator was still running, but it was silent. I haven't touched the capacitors. No need to screw around with something that isn't yet completely broken.
The only Soviet radio that really gave me trouble was a Selga 404. I think it was the first set to have silicon transistors in the converter & IF strip.
The Selga had one of the MP41 o/p pair defective, bad electrolytics and a corroded wire on a IF transformer due to excess flux from assembly. The Soviet small radios generally had decent sound quality for their size The Selga had a defective speaker as well.
The earphone socket was a unique size, maybe 3mm.
They sure don’t make radios like that anymore.
Russia niether. This little set Is a jewel, master piece for me. Electrónics, tecnology has evolutioned a big lot
What a collector's peace loving your video's
bono plex forna skoiler
Learning about circuits you have to treat all shotrs what caused the failure I'm finding out first hand that Changing capacitors doesn't always solve the issue I'm learning from your videos I learned I have to find out what the culprit is you teach me knowledge and wisdom
I'm surprised to see that this uses a regular 9 volt battery that you can just buy at the store.
What surprises me even more than that is that it uses the same AM frequency band that we use.
Why that surprises me is because, especially back when Stalin was ruling, there was a major focus on preventing citizens from being exposed to anti Soviet influences. Yes this radio was made around the time of détente, but it still it strikes me as strange that it would use the regular AM band instead of a different range of frequencies. AM signals can travel pretty far, and I would bet my bottom dollar that there were border blaster stations broadcasting anti Soviet messages.
на транзисторах указан 1969 год. А на гтшках указан 8 месяц 1969 года.
Would a little super glue work to secure those laminations?
I bet an Eagle LT44 would have worked as a replacement Audio Driver Transformer in this set.I notice you get quite a big Ferrite slab for the Aerial in these compared to western versions and I guess that helps the receiver sensitivity.Interesting that you could (just about) receive a station that was intended for Native American listeners.I wonder if there are many of these people left.
Ya can't win 'em all my friend, at least it didn't end in World Destruction :D I've got a similar dilemma with an old suitcase record player at the moment, audio output transformer is open on the primary, unwound and typically it's right at the first 3 turns of the thing... Unsure whether to bother trying to rewind it or just source a replacement. Think I'll replace it but keep the bits for when I know if the valves etc are any good maybe rewind it then. Interesting to see you post a vid with a transformer issue though. Good argument for leaving things well enough alone too.
Great performer! I’m wondering if that particular model was ever imported into the UK. Technical and Optical Equipment Limited, used to specialise in Russian gear, in the UK.
I think the tranceformer is better then what you
Had in there. Atleast you dont have to
Worry sbout those little e tranceformer cores
Falling out. I think you did an awsome job
At fixing it. I never haf to replace anything
In transister Radios Except the Speaker or
Tje 9 volt battery snap.
Isnt that an alnico magnet? I'm surprised there is that much stray field from an alnico.
Nice little radio
I have a few Soviet radios, well made but sadly the plastic really let's them down.
