Faulty BANG & OLUFSEN BOOMBOX from eBay - Trying to FIX 

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

"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.

Can i suggest putting some RU-vid Library Music on tape for demonstration purposes?

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.

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 used to love doing things like this, now I just enjoy watching others do it. Great video!

I love these retro fixes! Makes me happy when something old works like it's new again.

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.

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.

Awesome work as usual. It’s always a delight to watch you fix things! Makes me enjoy my coffee breaks even more.

So happy to see another Bang And Olufsen video from you! Love all the ones you’ve done.

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. 👍

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.

What a pleasing fix. Congratulations. And thanks for the joy of watching you make something right....

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.

You are like the mister Rogers of component repairs... I love watching your vids..

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!

I admire you Vince for not having any problems (seizures) when you try to fix such difficult (hieroglyphic) circuit board

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.

Thís brings back those good old days when I was a bench tech. Just like detector work. Always be happy when getting something accomplished.

That ferrite rod with coils around it is an AM tuner antenna.

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!

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....

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!

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.

Outstanding thank you for repairing this BoomBox Sir! It's greatly appreciated.

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.

B&O stuff is way ahead of it’s time style/design-wise.

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.

The cassette mechanism remembers me of my childhood. What a beautiful item, a real gem 😍

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!

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.

Awesome! Love boomboxes! I have a few myself.. thanks for sharing

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

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

Cheers Vince, always a cracking and enjoyable fixing video!

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.

Nice fix Vince, would never have expected some chewed up tape on the pinch roller to screw the tape up

That bit of tape being removed was SO satisfying 😌

good one!!! back in the day B&O was THE name for high end stereo and i wanted so badly 🙂

I love all your videos! Especially the trying to fix ones. Good one

Another nice fix Vince! B&O were nice machines but expensive like Bose! I enjoyed this as well!

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

As someone who also knows a dside from an eside it's been great watching your journey with this channel...

Great video I own one of these . I wish I knew how to attach photos to a RU-vid 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.

Love those real and serious restorations, where there's no layer of brown mud put on the gear by purpose to attract more viewers....

Just to let you know your got me hooked on fixing B&O.

You got a nice collection of B&O now, quality never gets old

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.

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.

I love your trying to fix videos and especially the long videos, Longer the better I say ☺ 😊

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.

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."

Brilliant fix video as always Vince. 👏

Valentines Day and love is in the air....Vince and a B&O product 😍

Absolutely brilliant!, wish you could find that missing panel though to complete it!

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.

That mic quality was better than expected. Could even get that cover 3D printed if you really wanted to.

The black ferrite rod with the copper wire coils wrapped around is the Mw and Lw Ariel. Nice work Vince.

Well MMV another good long video, love your work it’s so satisfying to watch. More please! Lol

It looks very heavy but I love the black. And you fixed it. Very nice!

thanks for the info I was able to repair my radio with ease because of this very informative video .... Thanks !!

Love the old school stuff you do/fix up it’s great 👍

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..

Another success, both the repair and the video.

If you use an fm transmitter you could broadcast public domain music to test radios and not have to worry about copyright.

Excellent fix for a cool looking device.

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 👍👍

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!

Love these indulging into the unknown type vids.

boy don't I remember the number of chewed up tapes, and once a machine does it once, then was forever chewing tapes until the broken bits were removed. As for a video showing it working or not, then it is better to watch right at the end, but think if I done this type of thing myself, then I would test it while still apart and off camera, unless something like building a pc as usually something like that requires you moving the pc from one place to another just to test if something is working.

14:37 - that's a ferrite antenna and it is used for MW and LW reception.

Nice find, thats an awesome little radio

Great, Another enjoyable video. I'm always amazed at why some hi fi equipment is so heavy.

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!

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!

love your videos, had hours of entertainment, thanks,

I watch all your videos your so clever keep up the great work

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.

Very entertaining, Vince. Thanks.

Keep up the good work fella and stay safe.

Great work on a superb radio

From my perspective Vince you can see the rubber roller bouncing up and down on the silver capstan which would account for increased wow and flutter and not in the radio side so something is caught in the capstan and roller Great video as usual and you can see where the weight comes from not those tiny tinny speakers but proper speakers with large magnets

There seemed to be a lot of residual dust in there. You may want to invest in a small air compressor to blow out all that dust. One of my best investments for repair/refurbish jobs. Love the trying to fix videos, buddy.

Really enjoy your B&O Videos!

I played around with one of those boxes back in the 80's when they first came out at a high-end electronics shop where I would purchase TEAC reel to reel cassettes tapes. I walked away unimpressed by it's sound and features . You could purchase a better sounding portable , that was bigger and cheaper . Nevertheless I'm glad to see some of them are still around today.

Brilliant fix, thanks.

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!

Haynes Manuals are... Special sometimes... For a 1994 Subaru Impreza, the instructions were as such. Removal of starter. 1) Remove the 3 bolts. 2) Installation is the reverse of removal. No pictures, no nothing. Just those two helpful instructions

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.

Just an idea, but if you're worried about copyright and/or have bad FM signal in your house, you could get one of those little FM transmitters used to listen to ipods/phones/etc on car radios that don't have an aux-in/bluetooth. That way you could play one of your videos or other non-copyrighted content for testing FM radio.

*Brillant* that wheel on the motor will not allow the belt from falling off.

It’s a known fact that vintage B&O always required patience and a knack to assemble it. Hence why so many “repairer’s” wanted nothing to do with repairing the brand, it takes time to get to know the products from Denmark , try fitting the radio tuner pcb on beocenter 2200 2100 4000 thats fun if you’ve never done one before.

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.

The drive roller on the motor is crowned. It's a well known technique for keep flat belts tracking true. I used to use the principal on conveyor runs. It does look odd when you first see it.

good job, and btw I loved the classical music on your tape,

Awesome video that is a very nice boom box

If you go in another audio device I would suggest putting a high pass filter on the speakers to protect them from the lowest frequencies below the fs of the drivers and increase clarity and power handling by blocking what they will not play well anyhow. Great video. Thank you.

Hi, the brown head in cassete department is for deletion of track and silver head have 4 cables 2 of them are for reading from the cassette and other two are for recording
