- Hi, in this video I try to repair a B&O Beosystem 10 purchased faulty on eBay. This was made between 1984 and 1991 and cost £249 back then.
The fault that was listed on eBay was that the sound fluctuates high and low.

Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince. - แนวปฏิบัติและการใช้ชีวิต
Late 80s and early 90s B&O design is just so classy. We’ve got an early 90s BeoCentre and it still looks futuristic even today
Can i suggest putting some TH-cam Library Music on tape for demonstration purposes?
I also would suggest if possible and a good reference tape deck is available to record a 440 Hz test tone on that test tape. Playing this back in the machines to repair the speed can be adjusted very easily using a frequenze messaurement app on a mobile phone.
"Unless of course it's lined with lead on the inside".
😂🤣
Every time I watch your B&O repairs I can't help but admire the craftsmanship that goes into their products.
I love any fix where the problem is clear when you get it apart. Seeing the that little bit of tape on the wheel was so exciting.
Ahhhhh, spoilers!!
@@WaffleClap don’t read the comments before watching the video if you don’t want ‘spoilers’.
On the tape transport, the dark coloured head is the erase head and the next is the rec/playback haed. The chewed-up tape was probably causing your cassette tape to skew across the pinch roller and not moving smoothly over the heads causing those fluctuations in the sound. Nicely repaired, Sir !!
I’m so happy
I used to love doing things like this, now I just enjoy watching others do it. Great video!
So happy to see another Bang And Olufsen video from you! Love all the ones you’ve done.
Thank you Josh, they are always interesting. I have another 2 to look at some time in the future 👍👍
Yeah, these products are timeless. I reworked some CX100 speakers for use in my garage recently with new surround foam and some Raspberry PI + 4 ch amp kit (HifiBerry - BeoCreate) available to make it into a modern WiFi/BT speaker. These >30 year old aluminum box speakers sound better than ever and look brand-new. I used to work at B&O in their R&D department.
You are like the mister Rogers of component repairs...
I love watching your vids..
Way to go Vince! You are slowly building up the high end B&O stereo system you always wanted when you were younger but could not afford it. 👍
I'd love to see you rocking up at a building site with this on your shoulder, Vince! 😂 What a lovely looking item though, those Danes sure know how to create a beautiful design.
🤣🤣With a lob sided limp because of the weight of it. I don't know how they make there products so heavy!! You're right though Steve, when you think about the other Boomboxes from that era this one still looks good today 👍
@@Mymatevince I think it was the speakers. they are more efficient? when they have larger metal pieces?
@@Mymatevince The black pinch roller looks like it`s gone egg shape on the tape deck... ??? i had the same problem on a Phillips unit when i was younger :):)
@Lassi Kinnunen 81 luckily, they still sell and make TV's, speakers and headphones worth buying. Those laptop gimmicks is just selling points for the laptop manufacturers sadly
Thanks for the video.
I wanted to see the inside of a Beosystem 10 for long, but never expected a video so clear and this long.
Probably this is the most detailed and the best videographed boombox repair video that I have ever seen.
Every tiny bit perfectly zoomed, exposed from correct angle, correct lighting, in crystal clear high definition video.
And the icing on the cake is that this video is created by a person who did not know the difference between Erase and Play/Record heads of a boombox at the time he did it.
Hats off to you!
That ferrite rod with coils around it is an AM tuner antenna.
thanks grandad
@@Rose.Of.Hizaki Referring to someone as a granddad can cause offense, especially if the person on the receiving end is far from the truth.
@@AppleOranges12 thanks grandma
@@Rose.Of.Hizaki As someone who mods and tinkers with old electronics, this hobby and knowledge of older technology don’t automatically turn me into geriatric. I very much enjoy my youth than you very much.
someone doesnt get that i meant it more out of respect for their knowledge rather than as a derogatory term. Grandfathers tend to be a great wealth of knowledge.
Awesome repair Vince... I have many hours of footage of me failing to repair BoomBox's, I have never put one out on the channel. Those tuning dial cords always get me! Nice fix.
I love these retro fixes! Makes me happy when something old works like it's new again.
Awesome work as usual. It’s always a delight to watch you fix things! Makes me enjoy my coffee breaks even more.
It’s nice to see you add another B&O to your collection Vince. B&O is one of those things that’s really worth buying broken and fixing up as they’re quite pricey when sold working. Nice one.
Yes these are £200 - £400 on eBay (asking prices, selling prices on hifishark are £150 - 250).
But they're nicer to have and use than to flip.
What a pleasing fix. Congratulations. And thanks for the joy of watching you make something right....
Another nice fix Vince! B&O were nice machines but expensive like Bose! I enjoyed this as well!
Cheers Vince, always a cracking and enjoyable fixing video!
Awesome! Love boomboxes! I have a few myself.. thanks for sharing
B&O stuff is way ahead of it’s time style/design-wise.
Outstanding thank you for repairing this BoomBox Sir! It's greatly appreciated.
The 'roller' that has the higher point to it that the belt goes on.
The belt will try to move to the highest point of the roller as they go round. The strength of the belt will only allow it to go so far, as the belt wears slightly or stretches over time it will still be able to keep the same tension as it will ride higher.
A pulley is made convex (aka. a crowned pulley) to auto-center a belt. When a rubber belt strays to the side it stretches more on the side that's closer to the center (because the pulley is convex). That stretched side bends outward toward the center a little bit, and that extra bit that sticks out towards the center catches on the roller and pulls the whole belt with it.
I admire you Vince for not having any problems (seizures) when you try to fix such difficult (hieroglyphic) circuit board
Brilliant fix video as always Vince. 👏
Watching you play with all the rollers and buttons was very amusing hahaha!
Also, I never could of thought that 80’s technology could be sooo complicated and tricky!
That bit of tape being removed was SO satisfying 😌
Thís brings back those good old days when I was a bench tech. Just like detector work. Always be happy when getting something accomplished.
Now that is my style of board to work on. I was trying to see how they are driving those 4-ohm speakers which look to be the 20 pin IC under the heatsink. Great job Vince and keep them coming!
That was a great fix Vince. I come across many similar issues with my repairs on cassette based multitrack recorders. Keep up the great work.
Hi Vince. The black one is the erase head that is an electro magnet. The middle one is record playback head. And the one with the tape wrapped around it is the pinch roller. Hope that helps you.
You were fortunate in that it came apart so easily. Bang & Olufsen were renowned for making some of their products very difficult to get into. It wasn't unusual for screws to be hidden under sections of 'stick on' costmetics' etc. It was partly to disuade engineers/technicians who weren't B&O's agents from doing repairs.
Funny you should say that, because I'm trying to remove the back panel on mine right now, and it will not come apart.
I've removed the 3 screws, but something is attached at the top, where the aerial end clips into place. It feels like a screw but I can't see anything there. Pulling at it bends the back panel, which will break if I lever it.
All i want to do is see if the belt is gone because the take up reel isn't turning.
And I can't find anywhere that sells belts for this model either :(((
The convex wheel on the motor is to help the belt center itself & run true... also might provide traction....
You see a "mild" convex shape in some bandsaw wheels also....
Great job on this one. Very nice....
The cassette mechanism remembers me of my childhood. What a beautiful item, a real gem 😍
Those were the holy grail of stereo equipment in the 1980s. You were paying for the name. Nice repair job. Its always rewarding having something working after doing such a lot of work. Very good!
Nah, they sound good too, for the size, FM reception is better than many other models because the aerial is extra long. It's quite featured too, with a wall mount and external speakers, the user manual even says max volume is at 6 unless using external speakers, it really has some power.
And with the rca inputs it can still be used today with bluetooth.
This was brought to you by the Beosystem Advisory Service for the promotion of Beosystem 10.
I love all your videos! Especially the trying to fix ones. Good one
Straight on this one! Loving these ones mate.
Your video was fantastic mate I absolutely loved it you did a fantastic job at taking it apart and fixing it I’m really proud of you mate well done 👍😊 I would love more of your trying to fix videos
Just to let you know your got me hooked on fixing B&O.
Love the old school stuff you do/fix up it’s great 👍
Reminds me of when I stole my sisters nail varnish remover to clean heads ( not the best but did the job)😅 back in the day… nice fix 👍
As someone who also knows a dside from an eside it's been great watching your journey with this channel...
Valentines Day and love is in the air....Vince and a B&O product 😍
Very entertaining, Vince. Thanks.
Love these indulging into the unknown type vids.
love your videos, had hours of entertainment, thanks,
Excellent fix for a cool looking device.
My first port 'O call after confirming the radio was ok was mechanical from the tape and I would go straight for the Capstan and clean the head for good measure...
Just got to the end of the video now and was pleased the system worked....Nice result Vince
good one!!! back in the day B&O was THE name for high end stereo and i wanted so badly 🙂
I love your trying to fix videos and especially the long videos, Longer the better I say ☺ 😊
Keep up the good work fella and stay safe.
It looks very heavy but I love the black. And you fixed it. Very nice!
Really enjoy your B&O Videos!
You got a nice collection of B&O now, quality never gets old
Well MMV another good long video, love your work it’s so satisfying to watch. More please! Lol
Nice find, thats an awesome little radio
Great video I own one of these . I wish I knew how to attach photos to a TH-cam comment. One really cool thing that you sort of glossed over is the fact it's a portable receiver. I've plugged in my 4004 and 8002 table and CX40 speakers for a full B&O system.
Nice fix Vince, would never have expected some chewed up tape on the pinch roller to screw the tape up
Great work on a superb radio
Great, Another enjoyable video. I'm always amazed at why some hi fi equipment is so heavy.
I suspect you could have taken that tape wrapped around the pinch roller out without taking the machine apart, but that wouldn't have made a very interesting video! Getting that for 40 quid was a bargain. Those B&O machines were made to last, unlike the cheap Chinese ones that are made nowadays.
Anything of that vintage was made to last. These days planned obselecence is the deal of the day - usually a product dies a day out of warranty.
thanks for the info I was able to repair my radio with ease because of this very informative video .... Thanks !!
just love your videos.. keep going!!
Great video fella 👍👍
Brilliant fix, thanks.
Nice one Vince; wonderful job on getting this B & O boombox working again.
You could do your workout by trying to lift it.
No one is going to nick it as it is too heavy to do so.
I watch all your videos your so clever keep up the great work
If you use an fm transmitter you could broadcast public domain music to test radios and not have to worry about copyright.
and also maybe he can ask Techmoan for some high quality recorded tape with royalty free music
You still have to worry about copyright. TH-cam punishes the creator for copyright claims regardless of their validity and entities constantly make claims against public domain works. Try uploading some public domain content if you don't believe it.
Am I'm allowed to tell you your better than ever? This was a fine radio/boombox if it wasn't for the cover missing it looks fairly mint!
Thank you!
🤣🤣 You are Anders👍 It is in very good condition considering the age.
Absolutely brilliant!, wish you could find that missing panel though to complete it!
Love those real and serious restorations, where there's no layer of brown mud put on the gear by purpose to attract more viewers....
good job, and btw I loved the classical music on your tape,
Job well done once again 🙂 👍
Awesome video that is a very nice boom box
I remember around 1984-85 when we lived in Central PA. There was a home show at our local event arena and our parents took us. I remember seeing a B&O television that was hanging on a wall. To me, at that age, this was an amazing thing to see. I remember my father saying that we wouldn't ever be able to afford something like that. Fast forward and my dad now has a 55" screen that he can tug effortlessly on a swinging bracket.
Great video! I always fancied one of these back in the day but a lot of money for what was essentially a quite basic Sanyo radio recorder wearing a sharp B&O designer suit. No Dolby or auto reverse were serious omissions at this price point but they did look wonderful! Ironically, at about the same time (1985-1987) humble Ferguson was offering decent all-in-one compact hi-fi systems made in Japan by Sony no less for about the same price as this B&O. And you got a choice of record deck or CD player thrown in!
The black ferrite rod with the copper wire coils wrapped around is the Mw and Lw Ariel.
Nice work Vince.
For a boombox that old it's actually really good quality and the sound is really good and loud it's really an impressive thing to see in 2021.
Great video... Thanks. When you say at the end of the video that "you can still hear the tape" ... that's called 'tape print through' ... the tapes fault; not the unit. Well done & thanks again for this and ALL your videos.
top left item wound in copper is the Ferrite Aeriel for AM reception
Have to agree with 'hifismiffy'! I learned to fix these as an apprentice, and I always found them scary! Jammed tape would have caused the roller to oscillate causing the tape to ride up the pinch roller. Great fix,. Cheers
again mate very done nicely done
Unfortunately this was the start of a slippery slope for B&O , basically charging top money for fancy outer casing and design but fitting other manufacturers inners , making a lot of their stuff unreliable , like the VCRs which if I remember correctly where Hitachi inners. I remember taking the back off a 21"MX4000 TV (£1500) in the 90s only to be confronted with a £300 Thompson chassis !!!
Much better when they made All their own stuff .
Great videos 👍👍
While looking at it disassembled, it's amazing to think about the amount of assembly effort that would have gone in to this product. Those trimmers, coils would all have to be tuned manually, never mind all the hand soldering.
4:50 I have to admit that I'm surprised that removing the tape from around the pinch roller actually fixed this problem, since I didn't hear any wow&flutter, only volume changes. I was wondering if the supply reel was getting ahead of the capstan, causing the tape to loose contact with the heads, and that might still have been the cause of the volume changes, but I'm mystified that there were not also severe pitch changes. Anyway, I picked up a 120V, no-LW version of this model at a pawn shop for $10 and the last time I tried it, one speaker had cut out. I've been dreading taking it apart and this video confirmed all of my apprehensions about its serviceability, but thanks for the tour of its innards; at least now I know what I'm up against. Though this B&O model seems to have a few "audiophile" features lacking in most '80s boomboxes, and very smooth sound, the single tone control (despite B&O's fancy name for it) would be a major disappointment in this price range; the model is gimmicky and not very practical as a portable. Ironically, it's so heavy that I fear that some of the flimsier plastic assemblies would be totally destroyed if it ever took a fall. It's a nice little piece of history, but I'm glad I didn't pay the original $300 price.
i recently got one of these (for a lot more than $10!!!) and I'm experiencing a similar problem - the sound balance might be normal for a few seconds but will roll to either the left or right speaker only. If I hit the 'AM' button, it seems to correct the wiring and be balanced again, but only for a moment. Very interested if you tried to fix yours and how it went?!
Great work
Great use of the word ‘nutter’ at the end.
I had a similar problem turn out to be a flat spot on the pinch wheel which on my first check I diagnosed a weak belt change that but it was the pinch wheel. Hope this may help with other tape decks. Thank for the videos.
That mic quality was better than expected. Could even get that cover 3D printed if you really wanted to.
I know you're trying your best with this piece of equipment. But I think that the words "Bang & Olufsen" and "Boombox" shouldn't be in the same sentence! I seem to remember that B&O had/have warrants from The Royal Court of Denmark. Keep up the good work sir!
Great video, glad ye got it fixed. Oh... That Archer's has some innuendos in the script lol. Saucy. 😆
Man, what a steal! I go the Goodwill and you be surprised what you can find. I found great Marantz receiver that only needed a filter capacitor! It was listed for $15. fixed for it $5!
Another great video
Nice work
I've seen capstan flywheels like that totally disintegrate. Something to do with the alloy (pot metal aka 'monkey metal'), and the dreaded 'zinc pest' or zinc rot. Dampness and high humidity can often trigger it..
I have seen other zinc things develop hairline cracks as they age. Guessing it is atmospheric
@@home-space Yes I've seen old dinky toys become brittle and start falling to bits in a similar fashion. Such a shame when it's something collectable..
The metal alloys age at different rates so the zinc and magnesium separate and it disintegrates. A lot of old razors were made of pot metal.
Removing the tape from the roller put me in mind of Star Trek II: The Wrath of Khan. I expected you to be like him extracting the grubs from the creature, "Not all at once. Not instantly, to be sure."
B&O always made very nice products!
Good video, thanks!
Nice fix :) The cracked flywheel brought in my mind a thing called diecast rot, if it's diecast metal? One of my model car suffered from it, altough this radio is much older. My modelcar was destroyed in less than ten years.
Zinc pest is another name for the phenomena.
Not sure though if the cracks at the flywheel are related to this or not.
I learned something today. I had heard of Tin Pest, but not Zinc Pest. That sent me down a rabbit-hole of learning which is always enjoyable to me.
@@TechGorilla1987 TH-cam & Internet at it's best, learning new things :) Have learned a lot from TH-cam videos myself, for example from MyMateVince videos ;)
That was my immediate thought. I collect toy steam engines of varying ages and zinc rot is one of the things to look out for on the cast parts (usually engine frames and flywheels coincidentally) particularly on older engines. It is nasty business especially when it's a structural part. It can write an engine off.
@@SimonNemeth Paya wheels were particularly bad, although I have seen an 00 locomotive where the frame bent like a Banana! The problem is caused by impurities in the Zinc and there is noting that can be done about it apart from the manufacturers using better quality Zinc.
@@MrDuncl It tends to be lead impurities and it primarily happens in cast zinc made at a certain time. It doesn't tend to be an issue with modern casting.
Superb pal thank you !!
