1970s Stylish BANG & OLUFSEN Beomaster 1900 with Numerous Faults

[@harryjones5260]

still remember that morning in 1979. aged 6. dad makes the tea and passes me the Beomaster 2000 brochure. whispering "we're getting one of these. DONT TELL YOUR MUM" my excitement knew no bounds. the future had arrived.

[@MrAsBBB]

I’m 55 and did the first ever GSCE in electronics and then got sponsored to do my electrical engineering qualifications. You should be proud of your fault finding expertises. It can be applied in so many environments. This should be taught to children. It would make so much of a difference to our world. I spend my working day is spent fault finding in data systems , the trouble is I am the only one able to do it in a company of 20k people. I am so overworked. I train people but they just find it either hard work or just not in their pay grade. All the best.

"What are you doing?" "Just watching a barely moving video of a man trying to get a bit of string around a small circle of plastic." "You what?!" "Best stuff on KZbin this. Now shush, please." 😁😆 Cracking fix, Vince. I have absolutely no use for one of these, but I really want one now - your enthusiasm is infectious.

[@faithless8888]

Hi Vince. The green “arrow” looking lights under the huge tuning dial, are not just for decoration, or to indicate stereo. They actually tell you, how to fine tune your station. If for example the left arrow is brighter that the right, just move the slider slightly to the left. You will see the left arrow decrease in brightness, because you are tuned in properly. Nice repair by the way! 🙂

[@Mymatevince]

Thank you, what a nice little touch. I wasn't sure how it worked. Thanks for telling me 👍

[@samuelfellows6923]

Similar to an “FM tuning” analog meter in vintage receivers = the resting position of the needle is in the middle of the meter, when tuning into a station the needle would deflect to the left/right on which side of the scale you were tuning into, and when centralised with the station the needle will [again] sit in the middle of the meter

[@2705fie]

hello from Denmark, I have worked as a technician for more than 40 years from 1967 repairing B&O's products, also beomarster 1900 I have e.g. converted a BM1900 to a BM2400. you bought the components at the B&O factory and built the print from scratch, when it became a BM 2400 it had a remote control so that all the functions could be controlled, this was with ultrasound which B&O used at the beginning also for TV. it is important that you wonder about the small round gizmos you find on the printed circuit board when you remove the metal bond, it is important that you put them back in as they must prevent the metal bond from being pressed onto the printed circuit board and short-circuiting. Another thing in your previous video with the 1960 radio you have put the scale cord the wrong way around the scale wheel, the arrow on the scale goes the wrong way when you turn the knob.😮

[@MsNIKITA]

The grey plug is the "BS5733 Masterpiece" a rewireable 3 pin, 6 Amp Masterplugs often used for hifi and home entertainment at one point. Very useful.

[@rc6133]

I had a set of these on my hifi years ago, took up a lot less space than the standard three pin plugs and a four way.

[@EudesRJ]

I saw it quickly on my phone, mistakenly with the Italian plug (type L)

[@jackmanatee3162]

In my teens (mid 70s) I remember drooling over the clean lines and beautiful functionality of B&O stereo equipment. Like the Beogram 4000c turntable, a work of art. But alas, I only had a Radio Shack budget.

[@sambuka57]

The 4000, 4002 .... I was in love SO BAD !!!!!. The catridge / stylus was the only issue to me. It is B&O specific. I think is is displayed at MOMA ? ....

[@mikeschumacher9715]

Had a couple of friends with these, back in the 70's. I have a fantastic B&O turntable now. Spendy but worth it. In the movie Christmas Vacation....the stereo destroyed by the ice coming through the neighbors window, is a Beogram 9000, Beocenter. Made me cry to see it destroyed.

[@NatureOkie]

Take heart, it was a prop copy wired to short, etc...not a real one. But, cool the set dresser used a real Beocenter as a bedroom radio....

[@jukingeo]

I laughed during that scene. B&O stuff really isn't that great. They break down very easy, they are hard to repair and they really don't sound any better than a Bose system. While the speakers were a bit better, (Many used Seas drivers, but the crossovers are utter garbage), their electronics are really nothing to write home about. It is just overhyped and overpriced stuff. You can definitely do better for less money.

[@NOWThatsRichy]

I first saw a brand new one of this exact model, back in 1977, a relative of mine bought one. When I went to their house, the then 9 year old me was absolutely amazed at how futuristic it looked, with all the red & green indicators & touch sensitive controls, when everything else at the time had big buttons & knobs!

[@Longplay_Games]

1970s and 80s design is, IMO, far more futuristic than our current "oh, look, it's a featureless black slab with a web service" design.

[@Hugh-S]

Couldn’t agree more.

[@danpedersen55]

Precisely, and in 40 years time,you haven't got a chance using what they make today, no knobs or sliders and the web interface is not compatible anymore, with the future OS. I'm not a fan.

[@38911bytefree]

But doing this requires a ton of industrial desing. I mean ... the B&O

[@chrisa2735-h3z]

I agree!!

[@snafu2350]

Yup. When do you think the Lambourghini Countach was originally designed? OK, it's horribly aerodynamically inefficient, but it looked seriously futuristic when it was launched.. & still does, IMO!

[@pauleastham2177]

That weirdo plug is a Micromark plug. Popular with UK audio separates fans around the mid 1980s. You can imagine with Amp, Tuner, Tape, CD, Turntable etc there were loads of mains plugs and sockets required. Using BS1363 plugs and extensions used up a lot of real estate at the back of the "tower". UK homes typically only had one or two sockets per room back then. Micromark nutters (like me) even shortened all the mains leads to route them nicely at the back. Also, mums didn't like to see "all those messy wires". They weren't cheap, but they were really neat.Also remember B&O was top dollar, Micromark was just what a B&O owner wanted. Loving the B&O videos.

[@andyevans2336]

I just restored one of these for a customer last month, including the matching cassette deck and Beogram linear turntable. Belts were the biggest difficulty in chasing down parts. Still sounds great after 46 years.

[@keithhoughton4308]

I have that cassette deck. Are you happy to share your source for the belts?

[@jamiekent1970]

Hi Vince, that plug you had was from a extension lead hub , i think the one I had was white and had 6 outlets, it was unfused you generally put 13amp UK plug on the other end with 3 or 5 amp fuse in to cover the 6 outputs… they were a lot small than having a 6 way extension lead behind the cabinet.. had mine around 1986

[@Mymatevince]

Thank you Jamie 👍👍

[@stuinNorway]

I had a similar one back around 89-90 but it was based on standard IEC plugs, similar in shape to PC (tower) power leads and kettle leads. That one looks more like the Italian style variation on the European plugs, some of them had a central earthc pin like that.

[@ralphj4012]

Exquisite. If you can find some slider pots of the same length you may find that you can change the tracks over, then use the new plastic parts, but, as another viewer mentioned, check first whether the pots are linear or log. The TO220 transistor should ideally have a plastic bush (part of a transistor kit) which passes through the tab and the mica washer as this would prevent shorting if the screw wanders, but the workaround is fine. The wandering slugs were a concern. Margot Robbie would clash with your decor, for Clive, on the other hand!

[@TheJensenInterceptor]

My uncle had one of these new and it was really so special I absolutely remember it......

[@dahger7]

Yes it's just a video. But you sir are a benefit to society with your kindness and good heart. It comes out in your videos. You could work on a boulder and it would be interesting.

[@funkykoldmodena]

Hello Vince, The knot in the tuning string is where the pointer is supposed to be connected. keeps the pointer in position Great video..

[@Smedleydog1]

I remember back in 79/80 a friend of mine worked at an audio store in the mall close to where we lived. Once in a while on Friday or Saturday night my friends and I would go out to eat, so we would meet at the store right before closing. We would play with all the audio candy while they were locking up, he would show us the latest and greatest, and we would drool over it. We were in college at the time and The Bang & Olufsen equipment was way out of my $2 price range.

[@lioneldickerson1550]

Hi Vince, this is an excellent repair and a superb quality B and O amplifier.

[@glengrimm4075]

Dude I love it when people like you geek out over old stuff like this, I was amazed just how gorgeously made that amp was made. It's a piece of 1970s art, I've owned amps from Yamaha, onkyo, technics, bose and this as basic as it is inside is a marvellous feat from an engineering point of view for the 70s you just know when you see something like this that's so futuristic but made so basic that it will last the test of time. And it still looks like it would suit any household from rent controlled housing projects to a massive mansion. I love companies that concentrate on sound quality rather than large sized amps and big muscle pumping base Where quality is overlooked in the search for high power. Dude I love you work and your videos keep it up, there isn't many people anymore that have the same passion or knowledge of quality audio, even If it is old. But then people like us know that mostly that is where the quality is. Stuck in the past. 👍

[@bramgn]

I appreciate that you show the radio not working after the repair, i wouldn't want to watch a repair video with just successes!

[@jukingeo]

It's a B&O. Witnessing a successful repair is a rarity.

[@mavis34]

Something that I didn't know existed but have come in really handy are 'RELIFE' PCB repair traces of all shapes and sizes, I'm sure a lot of people would have some use for them. That B&O Amp does not look like something from the 70's... Awesome stuff!

[@TheMcflyster]

Hi Vince! I bought on of these for 20£ and it had the exact same problem with balance. So I manage to fixed it thanks to your video. Thanks man! 👍

[@andytipping70]

Hi Vince - there are two different types of pot track - linear does indeed drop proportionally depending on position of the probes - but LOGARITHMIC (LOG) pots have the resistance kinda squeezed up at one end of the track - volume pots are usually logarithmic, balance is usually linear - just a thought?

[@Mymatevince]

Thanks Andy, I now remember being told this in the past. I think in this instance they were supposed to be linear, but I do need to remember your wise words for future repair attempts 👍👍👍

[@5mf1nc]

No, balance pots are entirely different!! They are 0 ohm in the middle for both and keeps it on one channel, while the other have carbon trace/increasing resistance.Same for the other direction. Something like: 10k/\/\0----0 and the other side 0----0\/\/10k (or sometimes using more complex circuit to use basic linear pots but those tends to be not as good keeping the center)

[@andrewmitchell9807]

Mesmirizing to wander through these pre IC hifi classics. Love the QUAD as well. Many thanks 👍

[@TrueBrit1]

Blimey Vince, that is a gorgeous looking thing. That looks so futuristic now, let alone 50 years ago! Class.

[@theoriginalrecycler]

That weird plug is a 1980s adapter from an extension block. I had a couple in red, plugged the main unit into mains and mine had 4 of those plugs in sockets in the main unit. Mine powered the tv a Betamax and a vhs and a receiver.

[@geoffh4578]

the transitors are dual for each channel which means there is no 4 channel output, the clue is written on the bottom, 30w output 2 channel and 15w output 4 channel, the speaker selection switch is another clue

[@helgew9008]

Correct. This is a class AB amplifier, so it uses two transistors for each channel, in a push-pull configuration. Given the age of the unit, I'd say they are bipolar transistors. One NPN and one PNP for each channel.

[@guidomersmann9744]

I always love when you refer to the old one naming it "my one" even so both are yours! :D

[@Asriazh]

the four powertransistors (the big ones at the back) aren't for four channels, they only do 2 channel stereo. The left channel uses a PNP and an NPN transistor and so does the right channel. NPN is for the positive swing of the sinewave (audio signal) PNP is for the negative swing. The balance potentiometers on that Bang & Olufsen potentiometer is a bit of an odd one. Normally at the center position, both channels would be at full volume and then, as you twist the button, one side would be dampened by increasing resistance. On this unit, the channel you move the balance slider to actually gets louder. Nice seeing this stereo being useable again. Thank You ^_^

[@Mymatevince]

Thank you Asriazh 👏

[@fathertiresias8561]

The other giveaway to the transistor configuration is the power rating printed on the bottom of the unit. It gives a speaker impedance of 4 ohms per speaker. The 2 speaker power output is double that of the 4 speaker output suggesting that when four speakers are used they will connect in series. Thus doubling the impedance and halving the power output.

[@JulesN580]

Ah memories! Picked up one of these in 1990 -with matching tuner/receiver, turntable and speakers in perfect nick - for $150 at a Richmond garage sale. Man l loved it!

Man.. B&O was the absolute audiophile favorite of the late 70's and early 80's. Quality audio and beautiful design. A shame there's no one to fill their shoes these days.

[@edwardfitz-gibbon6484]

Hi Vince. Those sliders can have different rates of change too. Logarithmic and liner. So swapping the tracks may give you the wrong one. So look out for ‘log’ or ‘lin’ markings. And yes the tone controls will have track for right and left channels. However you would probably not notice a difference between the channels if they had a slight difference in response between them. The “plastic” spacers for the transistors are probably thin mica. Good electrical insulator and good heat transfer. Don’t use plastic. It may melt. And the little round plastic insulator tube goes in the hole in the transistor. Nice video and what a time travel that was. Brilliant. Thanks

[@Mymatevince]

Thanks for the tips 👍

[@andyroberts9562]

Still watching and enjoying your videos Vince!, love how B&O put instructions on the case telling you how to dismantle it, seeing anything made by B&O reminds me of walking into a showroom years ago randomly pressing the touch sensitive buttons on the tuners & amps only for one to switch itself on at a thousand decibels, one of the staff had to come over and switch it off, i left the shop quite quickly after that

[@Zoli1972s]

Wow, and again, what a masterpiece of engineering back in the day, B&O. And they didn't have CAD, just a piece of paper and top notch engineering skills. Good repair Vince, and a beautiful outro with that lovely song, which immediately made it into my chillout playlist. Good choice for that beautiful set.

[@mrdali67]

And the funny thing is, the exterior design was made first and then they told the engineers to some how fit the electronics inside 😆 It can be an absolutely horror to service because how cramped up things often is in B&O gear but there is a reason they have several models that is shown in Museums of modern art. I have seen the test centers they had at that time. They got a buttload of Phillips CRT's for their televisions and about 80% was returned again for not living up to their high quality standards. I once asked a friend that had a B&O store back in the 80's about 2 different models of their Televisions, one costing around 10k DKR and one costing 20K+ what was the difference .. they looked 100% the same and he told me "The one on the left is a 99% Phillips TV in a B&O case and B&O remote, the right one is fully B&O design with the same CRT, but only 10-20% of the best CRT's is used, The rest Phillips get back". And its the same thing today if you buy a B&O flatscreen for 100k+ DKR, just that it's now either a LG or Samsug screens, but only the best ones. You can litteraly go out and buy the same Samsung screen for 20-30k, you just don't know how good your screen is gonna be. It could be just as good, but it could also be one that should/would have been scrapped for a B&O model. So you basically you pay 4-5 time the price for B&O to bin the screens and do a Calman adjustment. It's only their own software and remote system that is different from a Regular Samsung screen.

[@bathesheba111]

Hi Vince. I dont think anyone will make the carbon tracks, case of supply and demand. One solution is to bypass the faders. Use them as decoration only. Then attach micro potentiometers to the circuit board to bypass faders. Set them at a nominal value. Then have a flying lead to the back panel for a small potentiometer controlling volume. This is all easy to do and maintains the integrity of the B&O whilst still being able to enjoy its use. Sadly this problem applies to most vintage tech…..no more spares!!

[@markwagner1997]

Comming from Denmark this is so fun to watch, I remember In school I was out in a 14 day intern to find out what we wanted to work with when we graduating and I was in a small radio schack, And he just got a Beomaster 9000 in for repair (Top Model) looked like a freakin Startrek Spaceship control. If people don't know it, look it up. Kinda same design as this just 3 times as big and It cost like a yearly salary to buy .. lol. He opened it up and he removed a big Chip, Propably some VLSI type, and then turned it 180 degree and plugged it in again, and turned the Radio on and it starting speweing fault codes out on the display. And then he could look it up in the service manual which circuit was faulty. Absolutely groundbreaking tech at that time. And just think of todays Multi room wireless systems. Bang & Olufsen had that, (just wired) over 40 years ago.

You should have used a proper mica disk for insulating that transistor, not a piece of plastic because of better thermal transfer capabilities. A proper one for a TO-220 (that's the package of that transistor I think) costs only a few cents.

[@Mymatevince]

Thanks Kisslab, I have now bought a pack of 5 from eBay👍

[@helgew9008]

Also, that plastic isolation washer should have a shoulder on it, so that it goes slightly into the hole in the transistor. That way, it prevents the screw from touching the transistor. Oh, and hot glue on hot parts does not work.

The "bit of plastic" you're talking about is actually a piece of thermally conductive mica, and the sleeve that goes over the screw is supposed to stop motion from happening anyway. I would strongly recommend that you look up TO-220 insulating products rather than going with this solution because the plastic will melt if the transistor gets hot.

[@Mymatevince]

Hi Vince, few more old devices and we will call you My RetroMate Vince 😀 Nice fix!

[@Mymatevince]

Hahaha, it has a nice ring to it. BTW the pack of little files have arrived 👌

@@MymatevinceNice! Now you can do a manicure 😁(Just kidding) I really hope it will help you to file down all the plastic and metal leftovers.

@@Mymatevince BTW next time you clean those old surfaces, use IPA with a lower concentration. the 99.9% stuff is pretty strong for them. Use a higher concentration only after the lower one fails. 😎

15:49 right hand side of the screen. Ferrite beads need to be placed inside where the metal encasements are, you should see two metal areas one with two ferrite beads, and the other larger with around 4 to 6 components that need to have them as well, these will tune/Align the FM bands. With that tiny plastic washer for that transistor, it's shape should be situated so that the longer tubular part faces into the transistor, so that when you tighten the screw down, the washers tubular part is kept inside the transistors tab, purchase an insulating heatsink kit and you should see how that washer should be shaped like an open ended hat and "imagine your hair can be see from above with such a hat, so that when you shove the top end of the hat into a hole, you can shove your head into the hat without scraping your head from the holes rough surface, only with the transistor though you are shoving a screw into the isolating Hat, Err-washer..

Thank you Koala!!! I just ordered up some Mica plates and washers, dirt cheap, £2.75 delivered for a set of 5. Well done on spotting that on the ferrite cores, I didnt notice anything whilst filming or editing. I need to double check that ferrite metal plate thing in case they are indeed missing. All 5 FM channels appear to be tuning in fine though so I am hoping these are from another repair or a few viewers mentioned they are the remains of the feet???

I'm not surprised those sliders wore out. The displays look so good you can't help playing with them. 😃

My grandma used to have a black and white TV I believe from the early 60s that also had all touch buttons. I used to connect a wire to them and then touch the end of the wire to change channels or turn it on/off 😃

Vince that strange 3 pin plug is part of an extension instead of having 4 or 6 full size 13 amp plugs to connect all your Hi Fi equipment these came with 6 or 8 mini plugs (sort of space saver idea) I used the have one a few years ago it was a 13 amp plug with the adaptor on the other end of the cable,. I love your videos even though I know nothing about electronics I still find them interesting and entertaining, and like you if I do attempt a fix I love it when it works out, failing is not an option lol, Tom

Excellent video! For me, the Bang & Olufsen design from the '60s and '70s has a much more timeless design than their products from the '80s.

Very nice repair. Beautiful stereo

[@Decybello]

Rememer gettng Beomaster 8000 as a gift from my uncle who was living abroad... You probably can imagine, what all of my buddies were talking about for months after they've seen it 😁 No wonder, cause it was not only eye-wateringly expensive back in the 80's (it's cost was comparable to a cost of buying a good car in my country) and in my homeland just impossible to get....

[@Holycurative9610]

Great video Vince.. I love this old B & O stereo stuff but you need to be a real enthusiast to buy and maintain this kind of equipment. I just bought an enormous Sony amp (about 2006) and all 7 speakers for £70 and it's 1000W whereas this B & O amp/tuner is 60W but.... The B & O stuff has an amazing timeless style and isn't just piano black plastic so for looks I'd buy the B & O but for sheer power I'd stick with my Sony amp/tuner. I've also added a Bluetooth module to my Sony amp so I can play music from my phone/laptop although I can use an ipod mini which I've got but the battery is useless on it. If I had the room I'd have a house full of stereo from the 70s/80s as this was when I was getting into hifi separates and at 14-18 years old had some amazing kit in my bedroom so I'd have it for nostalgia but not for shaking the ornaments off my neighbours shelves when I turn up the volume to 11🤣🤣🤣🤣🤣

I can't get enough of this channel

[@stevehopwood6392]

what nice pice of audio equipment and the sound is fantastic the base is fantastic.

[@Ogma3bandcamp]

I still have my old B&O Beolab 1700 amp with the same issue. One channel down. I might have a look at it unless anyone's interested in buying it. I'm in Ireland and it's bloody heavy.
