@@shango066 thanks man. My shitty living as a caregiver keeping wonderful elderly people out of the death homes is very much brightened by your creativity.
Russian stuff is so fascinating! I have one reel to reel recorder, I had to change only one IC on the headphone output, just because my chinese headphone killed it
That radio sure is built awesomely...so sturdy, and everything inside is of good quality components laid out all nice and neat and orderly ... it's beautiful.
lots of owners ran these radios from 6x R20 cells, or 2x 4,5 volts batteries. They ran till the batteries started leaking from depletion. When these makeshift batteries were changed, it involved soldering them together with wires. We had to improvise these things, because batteries were expensive and hard to find in the now ex communist countries. This radio got damaged most probably because the user or repairman hooked its power up backwards for a few seconds. MP40-s were the universal AF transistors in many USSR civil and military designs.
In Germany (west) we had special longlife light bulbs (for traffic lights and hard to reach locations). They were rated for 25.000 or 50.000 hours. They had less than half the brightness of normal bulbs though. A 100Watt was dimmer than a normal 60Watt. There is no such thing as a free lunch...
@@albinklein7680 If you want your bulbs to last ages use a dimmer and don't run it past 80%. Use a deliberate slow reduction and increase when varying power. Any bulb if you run it under its rated power by X percent will experience an exponential increase in life expectancy, same with most electronic components. The most useful to know about being the electrolytic capacitor which at its rated temperature and voltage may offer a LE of say 1000 hours. If kept cool and run < (twenty percent below) rated voltage will last almost indefinitely. A bulb built to a rugged specification (like your traffic light bulb) will, when underrun last pretty much as long as the building its put in. There are always exceptions and other variables that can affect life expectancy though, ie electrolytics can dry out if seals are compromised. Bulbs can lose vacuum etc. They will all wear out in the end..but you can make some things last for ages. Especially if built in Germany...😺
@BMT Maybe you are not taking into consideration that the USSR launched the first and second satellites into orbit. Also the first man to orbit the earth, the first space walk and the first orbital station. It doesn't seem the equipment used by them were developed in the West since the West was lagging behind them. Even today, the US uses Soviet era motors for some rockets.
Commenting for added "Viewer engagement" and also loving these vintage USSR radios.. both for the interesting look at the iron curtain electronics and the comments vilifying the fact they actually made some good stuff over there back then
My dad had one of these in his shed up to the mid 1990s. He used to turn it on in the morning and turn it off at night. The damn thing blabbered on all day long for about 30 years and I'm not even sure if it quit working or my dad just switched to FM. I don' think he threw it away, I should check it next time I visit my parents.
Throughout the 1990s we had a great long wave station called Atlantic 252. It broadcast from a pair of 300kw transmitters on the west coast of Ireland (hence the name) and targeted the British Isles but apparently could be easily received on the eastern seaboard, and I bet this thing could have pulled it in even further inland. However it closed in the early 2000s and I don't think there's anything on LW now - all my radios are AM / FM only so I've no way if knowing for sure.
There are still about 10 longwave transmitters. Luxemburg and Ireland still have music programs on longwave. See mediumwave.de/#lw for the ones you can receive in Europe. There are still multiple megawatt stations on air, and occasionally you may be able to hear them. Apparently, Mongolia also has longwave transmitters but i never heard those so far.
@@mfbfreak thanks for that, very useful list! I've remembered that I have an old Sony clock radio with LW stashed away - haven't used it in years as the VFD went very dim, but as I recall it had a surprisingly sensitive tuner in it so maybe I'll dig it out later and see what I can pick up :)
Hello, my name is Vlad. I love old radios and collect them too. I have two "Вега 341" (Vega 341) radios and can present one of them to you, if you want. It's from 90s and has pretty good condition. Also don't be shy if you need any help with electronic parts, shemas, translation e.t c. Nice to meet you.
I always liked their 'Buran' space shuttle ... it only flew once and without a crew - but it landed all by itself on autopilot. Quite a good trick really.
@@cardboardboxification Not even close ! A commercial jet isn't an unpowered glider coming in at (presumably like the Space Shuttle) over 200mph. To quote Wikipedia .. 'Despite a lateral wind speed of 61.2 kilometres per hour (38.0 mph), Buran landed only 3 metres (9.8 ft) laterally and 10 metres (33 ft) longitudinally from the target marker'
Have a great Christmas . Love your vids and learn a lot from them . I had only worked on tube radios but after watching you I am starting to fix simple faults on transistor stuff . Take care and keep the vids coming ...Regards from Thomas in UK
I have one of these radios too. The speaker is fine, but it does sound very tinny. It works but it does have some weird whistle-y sound issues. I suspect they're mirror image signals, so the input filter may be tuned wrong. It is indeed used to be worn out. The volume knob has litterally gone smooth, the ridges are all smoothed out from turning it on and off thousands of times. I also used to have one of these complete in box, with the original mains power supply. The power supply is just a big-ish plug with vent holes, with a resistor and a diode in it. The little radio is supposed to isolate you from the mains... Very sketchy.
5:48 No external speaker connector. Battery charger connector. It had a factory 9 volt rechargeable battery. 10 million units were produced from the 7-transistor, 2-band pocket radio, which could be operated from a 9-volt battery, its own rechargeable battery, and mains.
The long wave aircraft beacons (NDB) were used for direction homing near an airport, they also sometimes had weather info in voice. They were not the primary aviation navigation, at least not after WWII. They were replaced by VOR stations which operated in the same VHF band as the AM plane to ground (or plane to plane) radios, but on separate channels. VOR's indicated the direction from the aircraft to the station as a heading on a compass like indicator which showed how far off a desired track the plane was. Aircraft later adopted the use of LORAN, and then GPS for navigation. I haven't flow (private pilot license) for almost 30 years now, I don't know how current civilian aircraft are equipped radio wise. I'm sure the VHF communication channels are still in use, but maybe have moved to FM or SSB, or even digital modulation. The VOR system is probably still available, but GPS is far easier to use. NDB's might be still maintained near major airports. I should get a recent sectional chart for some of this info.
I really enjoy your videos so informative and great be safe and careful out there wishing you a very merry christmas and a very happy and healthy and prosperous new year keep the great videos coming
I must say in defense Sony and Panasonic. In 1965 they were way ahead of Soviet consumer electronics. In the quality of materials used, quality of components, a variety of designs. However Russian transistor radios very interesting. Usually, they over-engineered in one way but have an annoying weakness in another. Interesting pieces of vintage equipment. I have vintage Soviet radios and can compare.
Greetings: If the other output transistor ia the same part #, use you little parts checker to learn the hfe and use that setup to hunt for compatible parts in your stash. Then you can try by touching the contenders until you find one that works. Don`t forget to note the equivalency.
I have a Selena multi-band radio, which works very well. Its FM-AFC band has no overlap with the US FM band. Do you know if it could be easily adjusted to pick up the US FM band? I wouldn't care if the dial is off. It already picks up a couple, I guess on harmonics.
I share your interest in former Soviet tech. We have a Okean 214 and a MP-64 Synychka along with a Soviet VTVM. Growing up in the 1970's we were always led to believe the inferiority of Soviet goods to find out that they were very comparable to older US produced tech in quality and ruggedness. The Okean works great, just needed a band selector cleaning and the MP64 needs caps, though this thing is built like a jigsaw pussle.. We also use some Soviet film caps in our re-cap jobs since they are a decent cheap for the quality providing you can wait for them to arrive .
We had an Okean 205 radio, but with black speaker grill like in Okean 204. retrotexnika.ru/img/tranzistornie%20priemniki/okean205%20raadioo.jpg rr20.ddns.net/Item.aspx?ItemId=5b2f7f51-ae56-4c60-b883-ea9386243820&Lang=En ltybc278.livejournal.com/100389.html ruclips.net/video/eqArUizD0p0/видео.html www.ebay.com/itm/RADIO-OCEAN-205-OKEAN-205-SOVIET-USSR-WORKING-RUSSIA-TRANSISTOR-RARE-VINTAGE-/224138521583 retrotexnika.ru/minskoe-po-gorizont-minskij-zavod-belvarp/radiopriemnik-okean-204.html
i build and design metal detector circuits for my hobby, i built one old design last year, some of the components are no longer made and are hard to find so i built it with supposed modern replacements, and it was shite! it gave false signals drifted all over the place ate batteries, during the first lockdown i made another board and built it with new old stock soviet parts off ebay, and other old stock parts, and it works great, some older parts are only available as soviet alternatives, given a choice between obsolete but correct parts and fake rubbish there is no compromise.
Gift radio here it is an aftermarket car radio close to and looks like a model 323T. 1964?. Worked when I put it in the attic 55 years ago. Capacitors dried out when I got it down and I recaped it and regermanium transistored it.It works nominally. I suspect it has silver mica disease. weighs about 4 lbs. Ill ship it to you if you want it...Russell
"Shango066" The MP40 output transistor may have been damaged if the + and - power is incorrectly connected. When replacing, it is advisable to change both transistors of a powerful stage - one year of manufacture and quality. And it seemed to me that the electrodes of the С-E transistor were messed up. In this case, the receiver will work but with distorted sound.
A bit about long wave broadcasting from Wikipedia. Frequency roughly 150 to 300 kilohertz. Way below the AM band. "Longwave is used for broadcasting only within ITU Region 1. The long-wave broadcasters are located in western, northern, central, and southeastern Europe, the former Soviet Union and parts of North Africa. Typically, a larger geographic area can be covered by a long-wave broadcast transmitter compared to a medium wave one. This is because LW ground-wave propagation suffers less attenuation due to ground conductivity.
Had shorted audio transistors and a very hot transformer yesterday, I hope the transformer survived. Edit: after swapping the transistors the radio works just fine, transformer is ok.
that thing looks mega brutal too. Function bent only. I'm working on a Univox amp right now, and it's got germ beercans in the preamp and the big germ outputs, really light wiring, 1X12 combo for guitar... could it seem like the preamp ones are bad with a shorted power one in there? just a random query.
That "big electrolytic cap" is a P401 transistor (or P402, depending on what they had on hand) under a metal can shielding. It's the second IF amplifier. I would put two P40s into this radio, no need to order the MP40 version.
On longwave, with a bit of an external antenna, maybe you will be able to hear the megawatt longwave stations that still broadcast in europe and the former soviet union. Russia and Belorussia have shut down already, but for instance the BBC keeps transmitting because on the carrier, there is load shedding control for the national grid.
I wonder why that news station sounds like it's in a pipe. it's all 'ringy' sounding, like they got an audio amplifier on the edge of oscillation. Here in indy we have a similar news station, and it too has this ringy quality. Is this some kind of encoding or something? like AM stereo as heard through a non-stereo radio? maybe it's what the nielsen rating devices use to determine what radio/tv station you're listening to/viewing. (those ratings receivers have a microphone and you carry it around with you, and it picks up encoded data in the audio of TV/radio stations)
On the other end of the spectrum, got a cheapo pocket radio with am/fm/sortwave, records and plays mp3s. And sweet metal retractable antenna. Easy to prank someone with an edited news recording heh.
Orange pieces are film capacitors if I'm not mistaken. Germanium МП series transistors are mainly intended for sound amplifiers.

I wonder if somebody had wired the connections wrong on the battery connector on the circuit board. I have only had these transistors fail on a set that the previous owner had put mains across. These transistors don't fail under normal use....
Serious question... Why do USSR made products use “English” words like “Made in” or “ Band” or “transistor”? Were these made for export? Are there domestic versions of these made? Thanks
I can't find Sokol-403 model with Russian text on it, but I found manual for it and description in Russian. It seems like this was an export model, but sold domestically too. Maybe this way was cheaper.
Yes,they were made for export markets.The domestic version was the same,only the dial/back cover slightly different. I also have a Sokol 403 in my collection with russian text on it.These ones were made usually for USSR and eastern Europe markets.

I have a Selena multi-band radio, which works very well. Its FM-AFC band has no overlap with the US FM band. Do you know if it could be easily adjusted to pick up the US FM band? I wouldn't care if the dial is off. It already picks up a couple, I guess on harmonics.
I share your interest in former Soviet tech. We have a Okean 214 and a MP-64 Synychka along with a Soviet VTVM. Growing up in the 1970's we were always led to believe the inferiority of Soviet goods to find out that they were very comparable to older US produced tech in quality and ruggedness. The Okean works great, just needed a band selector cleaning and the MP64 needs caps, though this thing is built like a jigsaw pussle.. We also use some Soviet film caps in our re-cap jobs since they are a decent cheap for the quality providing you can wait for them to arrive .
We had an Okean 205 radio, but with black speaker grill like in Okean 204.

i build and design metal detector circuits for my hobby, i built one old design last year, some of the components are no longer made and are hard to find so i built it with supposed modern replacements, and it was shite! it gave false signals drifted all over the place ate batteries, during the first lockdown i made another board and built it with new old stock soviet parts off ebay, and other old stock parts, and it works great, some older parts are only available as soviet alternatives, given a choice between obsolete but correct parts and fake rubbish there is no compromise.
Gift radio here it is an aftermarket car radio close to and looks like a model 323T. 1964?. Worked when I put it in the attic 55 years ago. Capacitors dried out when I got it down and I recaped it and regermanium transistored it.It works nominally. I suspect it has silver mica disease. weighs about 4 lbs. Ill ship it to you if you want it...Russell
The insides of the Russian radios are really engineering works of art compared to the radios made in the rest of the world.
Mixed colour transistors will work together just fine until the broadcasts create artificial tension
"Shango066" The MP40 output transistor may have been damaged if the + and - power is incorrectly connected. When replacing, it is advisable to change both transistors of a powerful stage - one year of manufacture and quality. And it seemed to me that the electrodes of the С-E transistor were messed up. In this case, the receiver will work but with distorted sound.
Please what's the equivalent of transistors
A bit about long wave broadcasting from Wikipedia. Frequency roughly 150 to 300 kilohertz. Way below the AM band.
"Longwave is used for broadcasting only within ITU Region 1. The long-wave broadcasters are located in western, northern, central, and southeastern Europe, the former Soviet Union and parts of North Africa.
Typically, a larger geographic area can be covered by a long-wave broadcast transmitter compared to a medium wave one. This is because LW ground-wave propagation suffers less attenuation due to ground conductivity.
Had shorted audio transistors and a very hot transformer yesterday, I hope the transformer survived.
Edit: after swapping the transistors the radio works just fine, transformer is ok.
I have been buying some the Russian transistors too
i have the same radio , still work prefect
Kripya radio chahie
MERRY CHRISTMAS 🎅🏻
that thing looks mega brutal too. Function bent only. I'm working on a Univox amp right now, and it's got germ beercans in the preamp and the big germ outputs, really light wiring, 1X12 combo for guitar... could it seem like the preamp ones are bad with a shorted power one in there? just a random query.
That "big electrolytic cap" is a P401 transistor (or P402, depending on what they had on hand) under a metal can shielding. It's the second IF amplifier.
I would put two P40s into this radio, no need to order the MP40 version.
Yep I forgot there was a transistor hidden in there. I ordered them anyway they are cheap
Soviet products keep forever 💪💪💪 say hello from Romania
MP40 was a newer version of the P40, they differed mostly by different case assembly technique (different welding or something like that)
On longwave, with a bit of an external antenna, maybe you will be able to hear the megawatt longwave stations that still broadcast in europe and the former soviet union.
Russia and Belorussia have shut down already, but for instance the BBC keeps transmitting because on the carrier, there is load shedding control for the national grid.
I wonder why that news station sounds like it's in a pipe. it's all 'ringy' sounding, like they got an audio amplifier on the edge of oscillation. Here in indy we have a similar news station, and it too has this ringy quality. Is this some kind of encoding or something? like AM stereo as heard through a non-stereo radio? maybe it's what the nielsen rating devices use to determine what radio/tv station you're listening to/viewing. (those ratings receivers have a microphone and you carry it around with you, and it picks up encoded data in the audio of TV/radio stations)
I wonder the same, have listened that kind of sound even on FM stations with music.
@11:11 ~ noting a red wire with what looks to be a bare part touching a solder point? is/was that anything?
EXCELLENT DUDE
@Shango : metric speakers no problem here in holland. how many mm diameter ?
On the other end of the spectrum, got a cheapo pocket radio with am/fm/sortwave, records and plays mp3s. And sweet metal retractable antenna. Easy to prank someone with an edited news recording heh.
There is no very Merry Christmas , over here in London England UK. So I am wishing you all, a very happy month and day that we are in.? :-(
Soviet germanium transistors can still short. It doesn't happen all that often but sometimes you get that issue.
Mery chrismas
And a happy newyear
Orange pieces are film capacitors if I'm not mistaken. Germanium МП series transistors are mainly intended for sound amplifiers.

Hope..that you can show us a video with a radio with red mercury...and explain why they used that!
the FM Band is russia used to be used from 65 to 74 mhz and Japan From 76 to 90 mhz fm band and tv in japan from 90 mhz up
I wonder if somebody had wired the connections wrong on the battery connector on the circuit board. I have only had these transistors fail on a set that the previous owner had put mains across. These transistors don't fail under normal use....
reverse polarity diode would be a great addition to this
shango
marry Christmas for you and yours family
Well that was interesting
in Soviet Russia the radio is listening to you :) my grandfather had such a SOKOL "falcon"
👍👍
You should just see Soviet TV sets or other home appliances they're just indestructible 😀 made to last for several generation
How does a Russian radio play American music and voices? Does it have a universal translator?
да. ;-)
This one is traitor.
haha,it's magic
Это магия )
lets not call it worn out but worn in. Ready to go for another 50 years
19:15 The dial pointer becomes 3 dimensional.😂
Got a bit turned on there
Транзисторы МП39, МП40, МП41, МП42 - германиевые
comments cut off on the latest zenith console resurrect??
not sure why myself
You can replace МП40 with МП41.
МП42 тоже можно
راديو روسي جميل جدا🇮🇶🥀🥀🥀

Serious question...
Why do USSR made products use “English” words like “Made in” or “ Band” or “transistor”?
Were these made for export? Are there domestic versions of these made?
Thanks
I can't find Sokol-403 model with Russian text on it, but I found manual for it and description in Russian. It seems like this was an export model, but sold domestically too. Maybe this way was cheaper.
Yes,they were made for export markets.The domestic version was the same,only the dial/back cover slightly different.
I also have a Sokol 403 in my collection with russian text on it.These ones were made usually for USSR and eastern Europe markets.

These radios were sold in England and France too, besides the eastern bloc.
Ток жрет потому что ушли рабочие точки транзисторов. Это PNP транзисторы. Необходимо подобрать смещение напряжение базы.
i use to have one long time ago
👍
2weeksto flatten the curve.. Remember that?
The question is...will you dissamble the variable cap? again.
@Shango066, I think that you'll enjoy visiting the "Life of Boris" Channel. 'Boris' is always good for a laugh, damn interesting, and great for looking at all-things Slavic and Russian - through a set of eyes which views life in a wildly unique fashion.
Sokol = Falcon ;) cool.
