- Here is a repair of the Bang & Olufsen HiFi from about 1984 to 1985.
A reasonably simple fix but dismantling to get at things is always the longest part of a job like this.
Music used in the video was composed and played by Markus Fuller - Jason Lee -Dan Ward 2018. - วิทยาศาสตร์และเทคโนโลยี
Massively underrated channel. Thanks for the hard work in putting all this together
Thanks for taking the time to make the video and share it
always nice to see a good repair, instead of see people throw out there things.
Nice repair job & relaxing music in the background...keep up the good work, both on repair videos & music composition
Welcome back Markus-I’m a Hifi nut so I loved this repair video
Great to have another repair / tear down video. Thanks.
Thanks so much for this. Super helpful, easy to follow, even amusingly self-deprecating. Fixed up my Beogram perfectly
Amazing vídeo. Congratulations and thanks for showing us!
Thanks much, Markus! very useful info for the vintage RX-2 that my old college roomie just sent to me. Needed a few tweaks like you have pointed out. Great job and also enjoyable to listen to your music. cheers
Thank you for your patience and understanding that most people would not have an inclination of what to do ... Your calm demeanor allows one the confidence to go ahead thank you Mark ...
Another interesting, informative, well-produced video, with great music. Really enjoy your channel - thanks!
Thank you
I quite like your music on the mate…..drifting….❤
"Why is the carpet wet Todd?" "I don't know Margo!"
Exactly what I was looking for ! Great video! Thank you!
Markus thanks for your videos on repairing this sort of thing, we just repaired my PC speakers, the main power plug had a dry solder joint like this! Saved me a few quid on buying a new pair for the sake of couple of mins with a soldering iron.
Very nicely done. just found a RX-2 and wanted to do some clean up on it. thank you Markus!!

Markus, I've got some news for you, your cloths are back in style. I'm not even kidding, teens these days walk around in your exact outfit!
"Clothes"
Yes I have noticed some of my old adidas gear is fetching silly prices on ebay.
NerveJam.Com No he was right the first time. “cloths” Lol.😂
And with criminals from eastern Europe XD
I'm sorry I'm not flawless in the third language I speak ;)
....picking up an RX2 turntable tomorrow and this was a very informative video. Thanks
They are excellent turntables hope you are enjoying yours.
Found a Beogram RX-2 Phono in a Goodwill for 13.00. Just rubs a bit when rotating, so this will be an absolute must watch for disassembly. Thanks much and appreciate the patient instructional form.
Never opened one myself, but from all I've seen online these old B&O hi-fi components are elegantly designed and for ease of repair.
More like,designed for unease of repair.
Really enjoyed this videos, pitched precisely and informatively. This system may as well have been a Bugatti Veyron in terms of affordability when I was young . I had Aiwa , Technics, Garrard and wharfdales cobbled together from Lasky’s
I remember a friend gave me his Amstrad hifi after he only owned it about 3 weeks. it was the most awful waste of plastic wood and metal ever created. I quickly passed it onto the next person and they too got rid of it quickly. Amstrad is Andrew Michael Sugars TRADing ( he has been made a lord now ) hmmm ? he must have done something right but I don't think it was his HiFi's.
Great fix Bang & Olufsen made some really nice gear back in the 80's

Great video, Markus! I had a friend who bought a B&O wall mount Cassette/CD/Amplifier/Tuner unit and column speakers. It cost a fortune and he had to have a tech from B&O come to the house and set it up. Of course, the tech talked him into buying a bunch of extras too! Sounded great (of course) but at a premium price. Still, it looked amazing! I think that is the biggest sell for B&O - they have brilliant looking designs.
True the design and styling is the thing that B&O is best known for. they have a shop a few miles from me and everything looks nice but the prices are very high.
First pronunciation was the best. Great video!
Great video! Thank you for sharing. I currently use a Beocenter 9000, Beolab Pentas, Beogram 9000 with SMMC3 from Sound-Smith, Beolink 1000, and Active 10 AM antenna. They make some really neat, well sounding, and beautiful devices. I hope you enjoyed this system.

Markus that was great, I have just bought the RX2 T/T, with the exact problems you have just
repaired, I will do my best to copy you, the seller said it hasn't been used for 20 years, just stored in a box, so I am hoping I can put it right. thanks so much. Ive just liked and subscribed, thanks again.
Colin.
Thanks Colin. I hope you get it working again. best wishes
Don’t kid yourself, Markus. You’re always in fashion. 👌🏽
What a great job
Thanks for sharing! Some Beocentre's were assembled at the Ultra (Thorn EMI), later Ferguson factory in Gosport, Hampshire, UK.
P.S. I forgot say, around the time of 1984/85
Just found that exact turntable on the street and I am so grateful for this video in giving me confidence in doing my own repairs on this. Cheers Markus.
The music sounds great!
Thank you very much
I still use my Bang & Olufsen speaker that I purchased in 1988, still sounds great.

Those look like hand drawn PCB patterns. Sweet video :)
Yes I noticed the hand drawn pcb also but forgot to mention them. good spotting :-)
I was a Hi Fi dealer back in the 70's / 80s .
Bang & Olufsen got taken over by Phillips which accounts for the use of Phillips components.
The motor spindle has a slight bulge in it so that the flat belt rides centrally on the motor spindle.
Replacing belts, grommets and styli were common place repairs back in the day.
What a daredevil,removing that top plate with the cartridge installed.Just repaired a Bang & Olufsen Beogram RX.It looks the same as the model in this video,but the only way to get to the guts is to remove the bottom and access from the bottom.No way to remove that top plate.Should have checked and adjusted the 33/45 speeds,while turntable was disassembled.
I have an RX2 with a shorted tonearm and I have retrofitted a T4P style cartridge to it, and it works great actually.
If memory serves that philips mechanism was a highly desirable one and sounded pretty good, in fact nowadays those original players are becoming quite expensive as the transports teamed up with a high quality DAC produce some really good sounds for digital. I had a Marantz that used it, cost me a small fortune in the eighties!
i found one of those on my doorstep .....very good sound output its about 200watts that thing with bass + treble ,ahead of there time they are
Nice to see you around again, and thanks forthe vid. I think the OEM scene was much bigger than we think. Even REVOX used a CD player mechanism from Philips. Telefunken used the Pickup and surrounding mechanics from Sony (KSS210 and KSS150). They also used VHS drive mechanics from JVC.I bet there is much more cross-usage of parts going on than we think.
There were only ever around half a dozen CD transport mechanism manufacturers in CD's heyday. Philips, Sony, Sanyo, and Panasonic were the most common ones. There were a couple of other minor players (all of the Japanese makes made variants of the Sony design in the 80s but fell away one by one) but if they weren't Philips or Japanese they were taking their components from Philips or Japanese almost exclusively. VCR mechs were the same - most makes ended up just taking complete units from Shintom.
Yes I see it so often. you open one thing up and its full of components from other manufacturers. especially in keyboards and synths.
Totally enjoyed that, many thanks! Nice JMJ feel to the credits music :) Sorry for spamming comments, I comment as I watch. Forgive me internet strangers :)
Thanks Michael. thats yet another incomplete unfinished track that I must get back onto one day and complete.
I like the JM Jarre-like music too. :-)
i've got a tx2 and an rx2 (the latter which i had to replace the tonearm on) - i love 'em both. most people are scared to deal with b&o because of the proprietary carts but soundsmith makes great replacements (even the $199 SMMC4 is great!) interesting that your RX2 platter has concentric circles - i guess there were different variations (both of mine have the lines emanating from the center)

When I was a young one, I would walk into those pricey hifi shops just to drool over B&O gear. As an adult, they had this 5 CD changer that was huge, vertical, with a motorized glass cover where you could see it do it's thing. SO cool ( still want one of those, lol)
I know the device you are talking about. its very sleek but I have no wall space for such a device.
I had a friend who bought one of those (or something similar because it had a cassette drive). Looked amazing and sounded really, really good. Oh, and cost a fortune and had to be "installed" by a B&O tech. You get what you pay for, and although he paid a lot, he was thrilled with his system!
Vangelis-like music
The Philips CD 104 was tops for its day. I owned two of these identical systems, and as they aged replacing the capacitors came to be an expensive issue..
Bravo !
Like watching an electronics sturgeon! Er...surgeon!
Sleek and stylish design, even by today's standards.
Markus or the hifi? 😁
Yes the styling is very futuristic
But belt drive turntable?!
B & O did a video 2000 in brown yes it had low cost insides this came from a house sell very likely
Hi markus, I have watched your videos for a good number of years, can you do a video on how to solder?
I found an all in one B & O system in the street with ‘please take’ - everything worked except the cassette.

Like your watch :)
First of your video I have watched. I really enjoy the approach you use.
It’s sadly a bygone era for this type of equipment, though it speak to the quality.
Will enjoy watching more !
Markus, where can I listen to your music ? iTunes, Spotify ? What name do you guys go under ?
kvfive Hi I have just a few of my own tracks on soundcloud under my name markusfuller . we three as a group just make a few tracks for fun when we get together but have not yet put any music anywhere as we just make the music for fun. hopefully sometime we should think about getting something completed and out for sharing.
markusfuller Thank you :-))
@@markusfuller Hi Markus, any chance you could upload the track from the video to your soundcloud?
bc_uk Hi theres the better revised version on another of my videos - look for “Apollo by JEM our synth session music track” .
I have to say, that's impressive looking engineering in some of the parts.
some parts are well engineered and yet the record deck looks cheap inside.
Did you get it for a good price Markus?
You haven't been doing many videos lately which is a shame. Always liked your projects. Hope to see more of you again.
Marantz offered a version of every Philips machine, each was identical apart from badge and colour. Marantz was owned by Philips at that point. Philips co-invented CD with Sony. Both introduced machines the same week. Philips didn't have their 16 bit DAC ready for production so the first machines had the 14 bit 4x over-sampled chipset. Sony had their 16 bit DACs from day one. The Philips machines for whatever reason? sounded really excellent next to the CDP101 from Sony. Very few manufacturers had the facility to produce a CD mechanism, this was cutting edge technology in 1983 - Anyone who didn't have millions and a decade to invest in R and D would pay either Philips or Sony . And it remained that way until cheap CD-R and so on were produced for pennies.
Edit. The list of companies using Philips mechanisms would fill about two pages.
Hey, great video, thank you :) I just got a Beogram 3000 turntable, which suffers from the exact same "motor squeeeek" noise when rotating. How did you fix the noise? Did "leveling" it up did the trick? Mine doesn't seem to have this problem. Just this rotating noise. Thanks!
Nice! What did you use to polish the aluminium on the turntable? I have a Beogram 2200 that I bought new around 1980, and still works well with new stylus and belt.
Hi, thank you for this video. I have both B&O 4000 and the 3300 set. My question: can the cd player be operated oner the terminal 3300?
Great Bang for your bucks ... ;)
I see what you did there, hee hee!
Liked your video and narration.
You could have just unsnapped and removed the MMC4 cartridge first, before taking out the plate! That is the most delicate and expensive part on your entire desk!
B&O, what I always wanted to buy but couldn't afford.
Yes they are a bit too expensive for me and I would never buy a new one a so had to settle for this second hand one.
The lack of space was less of an issue for the BeoCenters. They would wall mount.
Need to access the RCA cable solder points in the turntable. I do not see them from the top.
Just found your sit and loved the video. would you happen to know why the lights on the panel of a cd-x cd player do not come on even though the cd is spinning.?
they should be lit up. maybe theres a problem with the display or the chip that controld the diaplay.
B&O also had a VHS VCR range in the eighties , guess who made the innards , Philips .
that does’t surprise me :-)
It had the Charlie deck mechanics in it which had a C wrap system to load the tape relying on on a flimsy rack and clutch that wasn't terribly robust and used to lose teeth and jam.
My memory of seeing B&O gear in record stores in the 90s was that they tended to be wall-mounted (and insanely expensive). It looks like the CD player and cassette deck could be wall-mounted, but I'm assuming you'd need a Corinthian column to put the record player on?
I just wish I had the space to keep it all.
Could it be possible the turntable ticking was the belt teeth touching something, especially if it walked downward a little from the motor not being in alignment?
"For qualified servicemen only, and Markus" LOL
I wondered who would be the first to spot the easter egg :-)
Very smart indeed. Would it be possible to fit modern speaker terminals ?
Yes I guess there is enough room to add good terminals.
Hi Marcus thanks for the video. What synth and sequencer are you using in the background. Really like it. Cheers
Hi the main strings sound is from the crumar multiman-s plus there is the moog modular 55 and roland system-8
Cool they sound great, obviously i enjoyed the video but have been sequencing a bit recently and the tune caught my ears. Take care. Colin
That was a good find. It would have cost some money in 1984.
I have been looking at ebay and they still fetch crazy prices.
I paid $250 back in 84 for my RX2 display, he forgot to take off the cartridge & even called me to bring him an additional $125 for it. I told him I bought a display, they & they said nothing about paying for the cartridges' then so I didn't.
I'll be honest - I never got the desire for B&O and I still don't even with their new gear. You do find some cool stuff in car boots though. Are you going to use it Markus?
So the amp is not in the speakers? I suppose it's only 25 watts of power or something like that then?
Yes I guess you are about right there. they are not the greatest speakers but as a home unit it sounds ok.
I actually thought you had dropped your self in it as I initially thought Linear Tracking Turntable very complicated mechanically with cords and pulleys driving the tone arm along the surface of the record driven by a micro computer tied into the master computer in the base of the turntable.
Oh the linear tracking version is indeed a fiddly repair. I did one about 10 years ago and although i repaired it it was a difficult long task to complete.
That was unlikely to be an off-the-shelf Philips CD unit but rather an upgraded unit. Likely parts and calibration would have specified by engineers from the two companies; the upgrades may be difficult for outsiders to identify but typically were expensive. Source: B&O engineers and techs.
I would like to change out the RCA cables on my RX2 but no idea of how, I did replace the RCA plugs.
I forget now as its been a long time ago since i did this video. you would have unsolder the original cables inside the unit and solder on a new set to the board inside. sometimes you can buy ready made RCA cables and just cut them in half leaving 2 long wires with a plug at one end and cut cable at the other . then feed the cut canle through the hole and solder that into place.
I gmhave a beogram 2400. Need stylus and a speaker cable roars but can wiggle cable and is gone. What to do to fix.
Maybe you can do a video about the repair pricing of different devices.
I have no repair pricing as I only repair my own gear. I work full time on other work but sometimes feel i should be repairing for a living.
Digital converters were not very good in that era?
Could the stylus not be removed before working on it?
Yes, removing would make things a bit easier, and the piece of mind also.
I have to give this video an A-.. because at $150 U.S. to repair. I would have removed the cartridge before I flipped it over. otherwise this video absolutely a gem!
Are the music available online somewhere?
I think there are a few tracks left on soundcloud under the name markusfuller
Hi, is it possible to set the record levels on the ccassette deck without mass disassembly?
when I mean levels, L and R independantly. xxx
I had this model & setting the record levels was a breeze once the drawer was open, I had the optional remote console with mine & the levels could be set from that too, the list of options on customising the levels to your taste was mind blowing.
@@johnr6292 I've lifted the lid and the record level is just one slider. It seems to be 3db down on the right channel. I've cleaned and demaged the heads and playback is equal if I put a mono test tape in, I'm just putting off removing the bottom part. I am qualified BTW to do so, just I suffer from can't be arsed so just wondered if there's hidden pots under the silver trim over the decks.
Hi Markus my name is Paulo , I resonantly bought a B&O beogram 1102, the issue was that the guide return for the tone arm was out of its slot. I’ve managed to place the guide are back, unfortunately Im battling to fix the fly wheel in its position.
If you could assist me with some kind of working drawing or sketch I’ll be very grateful.
Philips made the CD transport for 90% of CDs
Hello,
The record player motor should not make that ticking noise but you can fix it
MMX-4H2RPB
Ticking motor cure,
Pry off the metal plate at the bottom,
Desolder the 2 contacts,
Pry off the pully (don’t damage the surface that touches the belt)
Now you have the motor on its own,
Now you want to carefully pry off the bottom bit of plastic evenly, as you can see through the hole you will be putting stress on the tiny spring contacts breaking these will make it non-repairable,
Now you have it off,
You will see the black disk supported in a plastic housing this housing breaks apart this is causing the clicking noise, carefully break away all the outer edge (the outer wall just about 3mm high) you might be able to just reassemble like this however sometimes there are cracks through the rest of the housing so I like to take some super glue on a cotton bud and wipe a thin layer over the remaining housing and then press the disk back firmly in place,
Now you want to reassemble it being careful of the brushes, if it does not spin then the brushes have been slightly bent out of position so open it again and add suitable tension to the brushed by bending as appropriate there should only be light contact.
Also, it's a good idea to put a tiny bit of oil on the bearings while open.

Hello Alistair. Thank you for your detailed repair guide for the turntable motor click. I no longer have this hi fi system but your instructions may help someone else in the future so I can always direct them to your comment here. Thank you very much for writing this. best wishes Markus.
those receivers/cassettes of b and o after 1975 were made by philips. everyone knows.. pure philips.
Do you fix other people B&O items
Hi Markus. I saw your video. I wanted to ask you for help. I have a 5121 cdx and a pulley broke. the reference number is 9032 2722037. would you know where to find it? thank you
Hi Orlando I am not sure where you will be able to find any spares at all for these machines as they are quite old. I sold my unit a while back and i have no idea if there are any spare parts still available.
@@markusfuller thanks for the quick answer. now it's a problem ..
Technically, Betamax went on to be very successful in the professional world, as Sony (and others) went on to become BetaSP, DigiBeta and BetaSX, in the broadcast world.
Nice video. I was wondering if you considered if the transport security screws were loose or tigth on the Beogram - that will affect the heigth of the motor in relation to the spindle. Another thing: I am sad to inform you, that the Beocenter 4000 is NOT a genuine B&O product. It is just the design - the inside is a standard crap japanese circuitry. Should never have been marketed, in my opinion
It´s Bang and Olufsen pronounced f like in Fox :-)
I would have 1st removed the cartridge to avoid any chance of accidental damage.
philips swingarm drives are unonstoppeble
Put some sellotape over the stylus man!!
Hello, do you want to help me with my Bang&Olufsen?
Hi Martin. I am sorry but I cannot take any repair work on at the moment as I am struggling to get through the things I have to sort out myself. my apologies.
Your "Olufsen" is correct. But "Bang" is pronounced with a deeper A in Danish - like the second A in "Garrard".
how much did you actually pay for this car boot sale item
The 2 or 3 times I found B&O stuff in flea markets it was very cheap, under 20 euros. For sure these devices are quite annoying by nowadays standards, as they are top loading and top controls they need they own furniture top space. One other thing I really dislike are those cheap crappy DIN plugs they use for the speakers.
Yes those din sockets are not very good. I dislike them also.
That is a common problem with many continental European HiFi pieces from the 70's and 80's, loads of DIN sockets and lots of different ways to wire them up, I don't really miss the days of having to make your own cables if you wanted to mix and match different manufacturers. #showingmyage
