- UPDATE:
I’m running a 3-part live workshop that takes us on… ’A Time Travel Through Vintage Electronics’
We’ll dive into the tech of the times, from the 1950s all the way to 2020s.
The dates and times are still to be confirmed. But if you're reading this, then the workshop hasn't yet taken place.

Mark takes on the 'service' of a 1977 vintage Bang & Olufsen Tape Deck, the Beocord 5000. Mistakes were made, by Mark mainly....
This video, really has a bit of everything in it!

I want to try something new. Something more live.
So I’m running a 3-part live workshop that takes us on…
A Time Travel Through Vintage Electronics.
We’ll rewind the clock, dive into the tech of the times…
(and study the very history of how things were broken and repaired has evolved)
From the 1950s all the way to 2020s.
It's still just an idea. The dates and times are to be confirmed.
But if you're reading this, then the workshop hasn't yet taken place.

This guy does not have enough subscribers, for this kind of high-level repair of all kinds of audio equipment. When a part is broken and can't be bought anymore, No problem; he makes it himself. Even all his explaining during the repair is very detailed and spot-on, and he knows what he is talking about. You won't find many of these kinds of technicians. I take my hat off to you, sir. Keep up the good work.
Hi, you mentioned the subscribers , I just checked and yt must have unsubscribed me 🤔
So have re-subscibed 👍
Yes a proper electro-mechanical engineer 👍.
Not only is he a mechanical genius, he’s also honest. He admits to mistakes that most creators would edit out to improve their public perception. I would rather meet Mark than most of today’s so-called celebrities. He’s a tip-top chap!
Indeed, Mark is a legend and how many repair technicians can just make a part like this. A true expert and fantastic to prove how we used to repair items all the time but now uts a throw away culture. Mark keep up the fantastic work keeping old kit running
Never ceases to amaze me with his depth of knowledge & ability to seemingly turn his hand to anything. There are other technicians making content fixing electronic items but none that I’ve seen that can do all the mechanical stuff that mark does.
I'm an 80 year old in Australia and I've spent most of my life fault finding and fixing things. I'd just like to say that Mark's electrical and engineering skill levels, always amaze me.
And the camera work and editing.....
Does anyone else get that unsettling panicked feeling in their stomach when Mark starts dismantling, knowing damn well you would never be able to put that thing together again?
100% Every time!
Had to replace the CMOS battery in my laptop once. Had no idea what I was doing. To make matters worse, the battery was in the most inaccessible place. Had to remove everything to get to it. Took photos every step of the way to make sure I reassembled everything properly. Did it! BUT I had at least six screws left over and now the touchpad doesn't work. Reassured myself that they always put extra screws in these things that you don't really need. And as for the touchpad, I use a mouse anyway, so as far as I'm concerned it's fixed! 😁😁
😆
Yes 🤦🏼♂️
I'd never remember where all those springs went
Yes! But having made a video of the disassembly would be a big help... right?
Mark is the David Attenborough of vintage restoration.
Best analogy (and mutually complimentary comment) today!
Mark you have skills in abundance, I bet most technicians would have given up & called it scrap.
Yep, I'd of thrown in the towel in a while ago!
a lot of technicians would not give up, it is all about economics, nothing else - no way is that a viable repair, those decks can be obtained in immaculate working condition for less than £50 so who on earth would pay to have that deck repaired unless he charges a 1950s hourly rate, but his mechanical skills are without question
@@Paul-qp5xs "those decks can be obtained in immaculate working condition for less than £50" Where? Not on ebay where I see one in good nick for £237.
50 quid will get you a scruffy looking non working unit.
Mark I'm 63 and have spent a lifetime in broadcast studio repair, but I'm always blown away with your ability and methods to fault find, love your channel ❤ and keep up the fantastic uploads and superb editing that must take you hours 👏 I echo all the positive comments here, and just to say you encourage me to keep repairing vintage technology as a hobby in my retirement, God Bless from a follower in Dublin.
Hola Joseph tenemos profesiones similares, tengo 66, jubilado, técnico de mantenimiento de estaciones de radiodifusión profesional y técnico operador de estudios de radio y tv. He pasado 44 años de mi vida reparando aparatos. Abrazo desde Buenos Aires, Argentina.
@@torugonza Gracias por tu mensaje, tendríamos mucho en común, comencé a arreglar cosas a los 12 años, en aquel entonces todo se podía arreglar, ahora es casi imposible conseguir piezas, ¡quieren que compres nuevas! Les envío mucha buena suerte irlandesa y saludos desde Irlanda.
I cannot believe the complexity of your fixes. The persons sending you their old high quality devices should know their only chance for a correct fix is you Mark. I have never seen such high quality work, what we used to get back in the 60's. From lifelong masters who are now gone. Your enjoyment is to be applauded. Thank you Mark.
And this is exactly why I'm SOL, since he's not accepting new devices to be repaired and hasn't for ages due to his backlog 🥲
KUDOS to Mark!!!!
>new Mend it Mark video just dropped
>it's 1:20 hour long
Strap in, lads. We're in for a good time 😎
I would watch every over 1 hour video if he releases it. This is such an amazing job, this guy is one of the reasons I do not waste my time watching TV.
Thing is it didn’t feel like 1:20
And it’s real , mistakes and all
I DID NOT miss ONE second of this presentation. It was like the "cliff hanger" in a Hollywood movie!
Casually makes a pulley from nylon like it's something he does every day - Watching these videos always reminds me that I really shouldn't give up as easily when attempting to fix my own equipment. Didn't realise auto-reverse was around in the 70's. Such a gorgeous mechanism.
Making those PRECISION pulleys is beyond awesome!!!
I am just in awe of the number of camera angles, close-ups and work that goes into filming this.. not to mention the skills and narration of repairs. The quality of this channel is under-appreciated, it's always so enjoyable and absorbing to watch your videos Mark. Hope you hit 100K subs soon!
Mark you have the patience of a saint. Really enjoyed your longer format. A real treat.
Expensive tape deck in the 70s, but great to see it brought back to life again by the MASTER !
The best electronics technician on TH-cam. 💯 I can't see enough of your repairs.
I love your videos and this one is extra long. The evening is saved. 😁
This bloke is an Engineer.
@@andymouse This Bloke is both an excellent mechanical Engineer and thee best electronics technician in the UK, period!
Agreed :)@@JCWise-sf9ww
Totally agree... wonderfully paced and fascinating to see the logic and the mechanics of older equipment being repaired. Awesome...
Another sterling repair Mark, love your patience and the fact you are not afraid to show your cockups whilst delving deeper into the repair and service.
"Some people use nail varnish here, but I ain't got any", yeah Mark we believe you!! Thanks for another brilliant upload!
We'll have to send him some. 😁
This is an insane amount of dedication to a repair I don't know of another person who would do this detailed of a job and look ecstatic while doing it honestly you deserve so many more subscribers than you have
Also I can't believe how over engineered this unit is but I guess 75 was a different time
Hello Mark! I dropped by to witness your latest repair and as per usual, you have blown my socks off yet again. I have commented several times, over the years on your previous repair videos and at this point, I truly am afraid of sounding (reading) like a broken record, however, I must clear my mind of the praise that you so rightfully deserve from me. You are simply AMAZING to me fine sir. You clearly have a skillset that is far beyond what is needed to perform these consumer electronics repairs in my opinion. I just cannot tell you enough of how awesome I think you are at what you do and generously show us all on these videos Mark. Once again, Thank You for sharing yourself with all of us. You are admired by myself and I honestly would not be surprised if other viewers felt the same way that I do. Please keep on posting these videos and also, please keep on smiling smiley! I walk away enriched from your videos with a smile every time. Thanks Mark! Fred
❤❤❤
Yet again, I bow to a MASTER!!! I'm inspired and awed every time. Making your own replacement pulley? WHO DOES THAT? Who has the skills, tools and materials to do so? WOW WOW WOW...
… so I’ll need to make a new one. Always my favorite line. Great video, Marc. Please keep making them.
The look on his face when he gets a jolt in the title sequence always make me laugh. Sorry Mark!
Capacitor got him
Amazing work, the mechanics, the electronics, the filming, editing - a deep bow for you Mark.
I just thought I'd check if you have any new videos...1 minute ago! That's my entertainment for the night
1 hour, 18 minutes and 51 seconds. Perfect.
Service with a smile (as always) and infinite patience!
That's 1:18:50 of my life I'll never get back. I enjoyed every second of it immensely! Your level of patience is something to behold. My heart sank when you had to pull the carriage out for the second time. Then my anxiety hit the roof when you forgot the belt. Thank you Mark for such riveting, educational and satisfying videos.
this is surprisingly currently being sold cheap for parts. I assume because most people do not have this level of expertise when it comes to fixing this model. Beautiful work Mark
Most technicians don't want to touch cassette decks. The number of people who will (and who have the skills to do it properly) are few.
@@sw6188 It's mainly the fact that those who do fix tape decks try to avoid needlessly complex PITA ones like this with parts made of unobtanium
(those PIHER potentiometers used for the record level control with the spring around the housing have been out of production since the 90s, and there's no modern drop-in replacement as their physical dimensions are all kinds of weird... just as one example of many)
@@KnaeckebrotsaegeYes, I know. I am one of only a few techs in my country who will touch cassette decks now. It's not just those however. I did a B & O Beogram unit last year and it took me hours to get it working properly. The slide faders are all starting to fall apart (I have done these machines previously and they had the same issue) and you can't get those any more either. I had to remove each one from the board, dismantle it, repair it (essentially brain surgery) and reinstall it. That was just to get them working right, not to mention all the other issues the unit had.
Unbelievable knowledge and technical understanding. Not only is Mark an electrician, he’s a mechanic, engineer and a master of vintage audio equipment of days gone by in my opinion. Keep up the good work Mark, always entertaining and informative, nothing too much trouble and always gets the equipment going with perseverance
I've been hearing people say that no one wants to service cassette decks any more in the country where I am, but I am still taking them on. However, I have never done a B & O cassette deck like this and I appreciate the insight into what is involved in working on one of these. I have done quite a few B & O Beogram units before and they are a time-sap. Easily 4 or 5 hours to go through and get one back on track by the time I replace all the leaking capacitors, repair the mechanical issues and replace the dead lamps, and it looks like their cassette decks require a similar time investment.
People watching this need to realize just how much work is involved in getting these units running properly again - it is no simple 5 minute repair.
Tiene que ser una tarea titánica.
B & O decks are rather weak as for the sound.
@@pearlvision7156 Yes. They look much better than they sound, and they often have operating procedures unique to B & O.
Another marathon repair, always a joy to watch. Keep up the great work👍👍👍
I've just taken up woodworking at 75 and every time I run into a problem I think I can't fix, I think of Mark. The man defines inspiration.
Beautiful repair Mark. These old B&O things mean a lot to me because my father worked there in the late 70s here in Denmark. He had some of them in my childhood home and I have some of this at home with me now.
Mark, every video you post, is an electronics repairing class, you are awesome!!!
It continues to amaze me, how well put together these old B&O units are. Love the design too. Great video!
Having fixed B&O systems before I am amazed by your patience in repairing this nasty piece of hardware without one single cursing. All my respect goes to you. ❤
Your repair videos are one of the best on YT, always a pleasure to watch a real craftsman at work. I'm absolutely not a B&O fanboy but this drive is build like a tank and last forever with a little love sometimes 😂
Thoroughly convinced I have multiplied my knowledge 10 fold with this one single video. Unexpected inspiration can be found here by all who apply the time very well spent. Im impressed beyond........!
this Beo tape deck required some major neuro surgery,,you have serious patience and knowledge ! you deserve an Oscar award
Feeling a bit sorry for myself today and then boom a new vid from mark, day changed.
Same here. Hope tomorrow is better for you. 👍
I get the same feeling when Mustie1 posts a video. Check him out, he's got the same positive never-say-die mindset at Mark but with ENGINES!!
If I had a complaint and it’s the only one I wish that all Marks videos were this length :) this was an absolutely fantastic repair. Thank you for letting us look over your shoulder while you work :)
Skills, craftsmaship, patience and great go-getter! Good camera work too. Admirable!
It’s good to see you’re not afraid to show your mistakes but also show how you find a solution. BRILLIANT!
The best electronics technician on TH-cam
Wow Mark, that was an absolutely epic repair, well done. You can see why B&O kit was so expensive back in the day, way beyond my purse.
I love this guy. What a gentle and nice personality. Getting to purpose of fixing vintage Hi-Fi gear these qualities are especially appreciated. I mean the man ground his own plastic pulley for goodness sakes which is a bit of a Herculean task. He did it all just basically saying "it's all part of a journey"...without any cussing that typically goes with repairing anything that is both mechanical and electrical. Mark, you're a real jewel of a person and a cracker-jack electronics repair technician. This was a somewhat daunting repair job. B&O did build stuff in this era like a tank. I'd venture to guess mechanically, after witnessing this, even more solid (less plastic for instance) than Nakamichi decks. Yet it definitely has some idiosyncrasies making it harder to troubleshoot and repair. With Mark's already keen knowledge of B&O, along with his almost paranormal trouble-shooting detective work, this unique deck is, perhaps, as good or better than the day it was shipped. Excellent video that despite it's involved lengthy repair was a joy to watch.
You're really amazing Mark! Thanks for taking us along on this repair.
What a cool device, great repair, and excellent video. Thanks again and great work, Mark!
I'm always looking forward to seeing another episode of "Mend It Mark" because of his positive attitude towards things, his skills and his determination to get things fixed, no matter what might get in the way. And also because of the joy to see old/er electronics and how well they were made, with being serviced in mind. Thank You Mark! ^_^
It's amazing the sheet steel work that goes into these old devices.
Blown away Mark!!! Brilliant repair. I’d love that unit!
What's amazing is that someone designed this, that person never gets a shout out so we'll done that person 👍
This was a treat. The editing of the feature movie must have taken as long as the repair. Great job!
I loved and I love '70 '80 decks: this is your most beautiful video. Thank you a lot dear Mark !!
Mark you patience is truly amazing.
When we reach the part in your videos Mark where you say _"I'll have to make one!"_ I know we're in for some fun - and by your look to the camera, you love it too mate ! Nice one as usual :)
One of the best channels on TH-cam for this type of stuff .Talk of Knowing your stuff .Must of hrs and hrs on this one one
You have incredible skills Mark - from someone who thought they had great skills - you're a super master - thank you1
@UCCJza9PAfxlJ0S8F4WNVGVA - so sorry, I'm not too sure what to do with these - I think there is an app for these @s?
Mark, I applaud you for documenting your mistake, fixing it, then saying move on with life and forget that happened. Great outlook! Learn and move on!
I have watched many electronics repairs and restorations over the past 10 years but nothing comes close to what and how you go about the diagnostics and fixes. You are the epitome of "Mark of ALL TRADES" since you not only thorough in fixing them gadgets but make any part that is within the scope of a DIY'rs domain. A pleasure to watch and learn if so inclined
Hello, what talent, what mastery. It's like surgery, you're so precise. Like a real puzzle to take apart, and especially to put back together afterwards.
Those anti-cam out screwdrivers are something I haven't seen before! I'll keep them in mind in case a situation arises that I'd need them haha
B & O did a lot of work refining Dolby HX and eventually sold the patent back to Dolby Labs where it was branded Dolby HX Pro. Very clever single ended way to squeeze more signal onto a tape.
Many Nakamichi decks do that without HX Pro.. Not sure how
@@maxfactor4209Other makers have done similar things to avoid paying Dolby license fees. Technics had an in house anti-saturation network that worked when Dolby C was engaged.
I had a 196 Pioneer With HX Pro and Pioneer's own BLE XD. BLE is auto tape tuning. XD is the anti-saturation. To be honest I could not tell the difference between HX Pro and XD.
This has to be among the best repair videos ever, really nicely done Mark! When you lathed that new plastic piece, bloody inspirational sir.
I always sit entranced with your videos, wondering how on earth someone can acquire so many diverse skills and practise them so expertly! Thoroughly enjoy your work. Thank you for putting these long-form entertainments together for us!
Brilliant! But boy is it over-engineered in some places, and under-engineered in others! I must admit, I would like to have done an LED replacement, as those indicator lights are awful. Also the level meters did not look setup, with one channel more than 5dB over the other. But man, you are patient! Love your work, and the extra mile you always go!
"Forgot the belt" - I felt that.. Haha. Don't forget to check those small value Roederstein caps - Most of them will probably have gone bad over the years. At least in their amps.. but then, those are more toasty as well.
A mending video on a Saturday evening. What a wonderful treat!
Wow what a repair job I didn't expect the lathe to come out. Blown away! Looks like an old Ferrograph demagnetiser like mine too. 😊
There could have been some new swear words made up for this one but you calmly just figured it out and brought it back from the dead. Great work Mark 👍👍
Beocord 5000 is made 100% by B&O, it is the only machine that they have made from scratch, the mechanism is with a double capstan and very nice of the time, it is NOT an easy machine to service but you do it fine I must say, I have made a number of them myself over time and know them quite well, but again nice work .. Many greetings from Denmark and an old B&O employee.
Cuando un cliente cree que el aparato tiene un alambre suelto y por eso la reparación es grátis, hay que hacerle ver este video. Muchas gracias por compartirlo, generando conciencia del sacrificio que es ser Sérvice.
Not sure how I’m only finding this channel now. This is the channel i needed in my life.
On almost every step of your repair I had said "Hands up, it is not worthy further".
Your work is impressive. Todays world it is hard to find a tradesman that can make their own replacement parts, most today are parts changers.
I always admire your patience! Every Beocord is a nightmare, it's too complicated.
I don't believe there are many people with this level of expertise...amazing work
Lots of patience.
Lots and lots of professionalism
Love your videos Mark, pre-thumbs up before watching every video 👍Keep 'em coming!
Love the Delrin pulley you made, Delrin is a great material to lathe, bit like PTFE, did a similar repair to a turntable a few years back.The nail varnish reference was funny, we used it for keeping setup preset trim pots, on alarm circuit boards back in the late 70's ,from moving after calibration setting. These old mechanisums are frustrating at times,but great for learning how to fix faults, Great job Mark,
Someone could have taken it to the tip or sold it for not working for a tenner, but you never give up, hats off Mark, it was an absolute honour to meet you in person. Thanks for the video
Very impressive repair. What im also impressed by is the amount of what looks like hobbed metal in this thing, really built to last.
Oh i ruined the pulley, I just make a new one. "Normal" people would have cried and might have used a 3D printer if they had one - real men use a lathe - This is sooooo cool
It's disgusting, but scammers are using your channel to send spam on your behalf (
Blame TH-cam
Mark , i never get sick of watching you fixing all kind of things.
Listening to your comments is a good practice for my English too. 😜
I have no idea what this guy is doing but I can’t stop,watching!!!
I remember back in school we had a whole section in the books about how to read schematics from B&O. They kind of had their own way about those. Brings back memories. For instance if a signal go from one page to the other the edge symbol is reversed in direction if I don’t remember wrong. Easy to go looking the wrong direction.
My dude, you are everything that is right in this world, I have a long career of IT and systems troubleshooting and I couldn't fathom having your patience and endurance, thank you, from the bottom of my heart for making this video. 38 years old.
It drives me nuts just by watching the repair / restoriation ... thank you Mark! :)
Watched this, mesmerised. Amazing patience and memory. I'd never be able to put all the bits back! Fascinating and entertaining.
Superb skill level and the patience of a saint!
Thank you for including the whole journey Mark. Gives those of us attempting similar projects hope!
Wow, that was a very thorough service. Nicely done. I'm still amazed at how well things used to be made unlike today's garbage. And serviceable. Now everything is engineered to fail on purpose. Engineered obsolescence.
Epic level of skill, patience and cheer, Mark. The level of design complexity for tape decks is another thing that blows my mind. I dread to think how much this repair bill was 😄
amazing repair - well done Mark!
That was masterful Mark. I took a cassette deck apart when I was a kid and that was that. I couldn't get it to togther again. My mate had a B & O system that was about 20 years old. We thought he was posh even though he was rough. Great job bringing it back together for future generations.
Awesome as Always... My Grandparents had this, and the buttons where hit and miss even when new... Did not like to get dusty..Gave me goosebumps' to see it again :D
Always a plaesure to watch you work and hear your commentary!
Its also very comforting to see how you respond to struggles in the process of repairing. Sometimes you just have to break stuff to get a step further and then just concentrate on the stuff that you broke in the process, no truble.
Hi Mark so many memories i used to have the B&O amplifier of the same series a wonderful work of art for the time
best electronics repair and restore channel on the tube.
A super tech with the patience of Job. Never disappointing .
Mark, you're a genius. That was an amazing piece of servicing. Much like a test of endurance, I'd say. I thoroughly enjoyed watching it.
