UPDATE: 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) The workshop is coming soon, but if you're reading this then you're in luck (or not)... And there's still time for you to sign up using the link below: www.menditmark.com/mend-mark-workshop The workshop dates are mentioned in the link above too.
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.
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.
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! 😁😁
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.
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
Yea the guy has an amazing amount of skills, but can't imagine anyone wanting a £400 repair bill for a at best £50 old tape deck. I'm thinking these videos are more about how to repair than someone actually taking these items for repair. I watched one with an old late 80s all in one Sony stereo that was busted and new labels were also printed for where the old ones were worn out, busted record deck and cassette deck, the repair bill would be ridiculous for something that's pretty much given away today
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.
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!
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.
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.
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.
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
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...
My late father was a super electronics technician and he was the only authorized repairman for the B&O company and I salut you for your excellent expertise. I still have the B&O bottle opener connected to my keychain as a reminder of that ‘70’s era. 💎
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. 😁
So I’m watching you pick apart that little motor and I’m thinking that goes in the bin and you find a replacement. Nope, you actually go and do a rewind job AND you have a gadget to do it. Mind boggling thoroughness. I`ve done a few fixes in my time but this is sensei level - and also a tad inspirational.
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.
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
He could have been a great clockworker too .. remarkable skills shown in this repair. It's obvious he enjoys every challenge in these videos more than the possible revenue 🧐😎 Most of us would have run screaming away and thrown the thing in the dumbster🤯
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
@@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.
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.
They were quite well made and sturdy for the time as long as they worked, but everyone that have repaired B&O gear will know it usually was a knightmare to disasemble, access and repair if something went wrong, especially with their somewhat awkward solutions to make the units look smart on the outside. Just hope you'll never need to repair it 🙃
the B&O way. Design the casing as smart as possible send it to the engineers "Make something that fits in the case !!" don't think of if it's able to be fixed if it breaks. We just sell the custommer a new machine.
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 :)
I probably would have lost it, putting all that stuff back together then realizing I missed a belt, but Mark just smiles and does what needs to be done. Patience of a saint!
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.
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.
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 😂
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.
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. ❤
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! ^_^
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........!
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.
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!
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
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.
Astonishing to see such skill and to be able to repair something so "ancient". Thank you so much for taking the time to create all these wonderful videos!
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 :)
I really really really appreciate that you never rubbish the equipment you are working on. Most techs would bitch and moan non stop while disassembling something like a B&O product. Then they'd go about reengineering everything while telling us how stupid the original engineers were and how much better they are. All the while never mentioning the product they are working on is 50 years old and other than fair wear and tear, and possibly a cap and resistor or two, the unit is still fine.
"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.
Seeing that Mauritron manual brought back memories. Glad to see they're still in business. Excellent repair as always. In this digital age, I love it when you do some good old fashioned analogue troubleshooting.
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.
@@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.
B & O invented HX (just a thing that adjust the bias based on the amount of high frequency in the recorded signal) and then they sold the patent to Dolby, and Dolby made one or more integrated circuits that did all the magic in a simple way.
1hr18mins just flew by. Totally engrossed and completely in awe of your technical knowledge and expertise. I applaud you sir and long may you continue providing such entertaining and informative content.
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
Another amazing repair Mark. I repaired audio equipment from being a hobbyist at 12 years old to present day, age 71 now. You are the best I've ever seen. I had a contract with a local shop to deliver and repair their audio equipment, they were the main B & O dealer in our area, so I was forced to have to repair the stuff. I absolutely detested it, particularly the cassette decks. I must admit, I did like the look of the B & O TV's back in the day, but all of it was way over-priced and overrated.
Gotta say the level of skill and perseverance is staggering. I’m amazed by how Mark repairs stuff. I’d take anything to him for repair. Start a business. You’d make a fortune. (Or am I behind here) I use to have this unit so this caught my eye this is my first video I seen. Subscribed already
Wow! This machine had a lot of problems. Hard to believe you solved them all. My favorite part was when you traced that brown wire to the cassette deck and found that two solder joints were touching. Seperating them solved the problem with the record function. Awesome work.
That certainly qualifies as a truly epic repair. Definitely one where you're snookered without the manual!. I now realise why they were so expensive back in the day., too. Thanks for another great video.
You're way more happy than I am when I have to pull something apart for the third time. Great repair. Super impressed with that new wheel that you made. These things are definitely way more complicated than they needed to be. I've serviced a lot of cassette decks and this one looks like a complete trip!!!
Manufacturing that nylon pulley was next level. If it wasn't a Bang and Olufsen it wouldn't have been worth repairing. I was glued to my monitor watching this one. Your perseverance is amazing.
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.
pulling the spindle out of the tape deck with the frewheel mech etc, everything falls apart. I would absolutely cack myself yet you remain entirely undaunted and press on with positivity! Bravo!
I really enjoy watching you. Not only the repairs, I think your explanations also have an educational aspect. I look forward to continuing your perfect repairs or diagnostics. Well done.
I've never seen a person who can weave his way through problems like Mark! Ebay shows many of these units requiring new belts. That in itself is a major take on. Hats off to you from a retired technician from the USA.

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 :)
This was a treat. The editing of the feature movie must have taken as long as the repair. Great job!
I probably would have lost it, putting all that stuff back together then realizing I missed a belt, but Mark just smiles and does what needs to be done. Patience of a saint!
This has to be among the best repair videos ever, really nicely done Mark! When you lathed that new plastic piece, bloody inspirational sir.
Excellent teflon -replacement! Well done! Greetings from Germany
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.
Blown away Mark!!! Brilliant repair. I’d love that unit!
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.
even the motors?
I loved and I love '70 '80 decks: this is your most beautiful video. Thank you a lot dear Mark !!
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 😂
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.
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.
You're really amazing Mark! Thanks for taking us along on this repair.
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
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. ❤
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! ^_^
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........!
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.
Mark, every video you post, is an electronics repairing class, you are awesome!!!
What a cool device, great repair, and excellent video. Thanks again and great work, Mark!
I don't believe there are many people with this level of expertise...amazing work
What's amazing is that someone designed this, that person never gets a shout out so we'll done that person 👍
Just terrific. I don't know which I admire more, your fearlessness or your unflappable good cheer. You're a model for us all!
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!
Skills, craftsmaship, patience and great go-getter! Good camera work too. Admirable!
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!
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
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!!
I am in awe at your skills and your patience when it comes to mending, Mark. Absolutely marvelous to behold. Thank you!
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.
Astonishing to see such skill and to be able to repair something so "ancient". Thank you so much for taking the time to create all these wonderful videos!
The best electronics technician on TH-cam
You have a valuable gift sir....
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 :)
Mark you patience is truly amazing.
The look on his face when he gets a jolt in the title sequence always make me laugh. Sorry Mark!
Capacitor got him
I really really really appreciate that you never rubbish the equipment you are working on. Most techs would bitch and moan non stop while disassembling something like a B&O product. Then they'd go about reengineering everything while telling us how stupid the original engineers were and how much better they are. All the while never mentioning the product they are working on is 50 years old and other than fair wear and tear, and possibly a cap and resistor or two, the unit is still fine.
Love your videos Mark, pre-thumbs up before watching every video 👍Keep 'em coming!
Not sure how I’m only finding this channel now. This is the channel i needed in my life.
"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.
Seeing that Mauritron manual brought back memories. Glad to see they're still in business.
Excellent repair as always. In this digital age, I love it when you do some good old fashioned analogue troubleshooting.
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.
@@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.
B & O invented HX (just a thing that adjust the bias based on the amount of high frequency in the recorded signal) and then they sold the patent to Dolby, and Dolby made one or more integrated circuits that did all the magic in a simple way.
1hr18mins just flew by. Totally engrossed and completely in awe of your technical knowledge and expertise. I applaud you sir and long may you continue providing such entertaining and informative content.
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 good to see you’re not afraid to show your mistakes but also show how you find a solution. BRILLIANT!
It drives me nuts just by watching the repair / restoriation ... thank you Mark! :)
It's disgusting, but scammers are using your channel to send spam on your behalf (
Blame TH-cam
Another amazing repair Mark. I repaired audio equipment from being a hobbyist at 12 years old to present day, age 71 now. You are the best I've ever seen. I had a contract with a local shop to deliver and repair their audio equipment, they were the main B & O dealer in our area, so I was forced to have to repair the stuff. I absolutely detested it, particularly the cassette decks. I must admit, I did like the look of the B & O TV's back in the day, but all of it was way over-priced and overrated.
Gotta say the level of skill and perseverance is staggering. I’m amazed by how Mark repairs stuff. I’d take anything to him for repair. Start a business. You’d make a fortune. (Or am I behind here) I use to have this unit so this caught my eye this is my first video I seen. Subscribed already
Wow! This machine had a lot of problems. Hard to believe you solved them all. My favorite part was when you traced that brown wire to the cassette deck and found that two solder joints were touching. Seperating them solved the problem with the record function. Awesome work.
Your patience with taking all the little screws and pieces apart and putting them back together is commendable 👍🏼
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. 😊
I think its a Wearite'. Pretty sure it's the type I used back in the 70s.
Mark , I spend a lot of my free time doing repairs on older vintage radios . It's great to see how detailed you are . Thank you very much ! Rob
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.
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?
That certainly qualifies as a truly epic repair. Definitely one where you're snookered without the manual!. I now realise why they were so expensive back in the day., too. Thanks for another great video.
You're way more happy than I am when I have to pull something apart for the third time. Great repair. Super impressed with that new wheel that you made. These things are definitely way more complicated than they needed to be. I've serviced a lot of cassette decks and this one looks like a complete trip!!!
Absolutely incredible...knowledge,patience,optimism, persistence,creativity....Mark you are a techinical genius!!!
Manufacturing that nylon pulley was next level. If it wasn't a Bang and Olufsen it wouldn't have been worth repairing. I was glued to my monitor watching this one. Your perseverance is amazing.
Service with a smile (as always) and infinite patience!
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.
pulling the spindle out of the tape deck with the frewheel mech etc, everything falls apart. I would absolutely cack myself yet you remain entirely undaunted and press on with positivity! Bravo!
I really enjoy watching you. Not only the repairs, I think your explanations also have an educational aspect. I look forward to continuing your perfect repairs or diagnostics. Well done.
Thank you for including the whole journey Mark. Gives those of us attempting similar projects hope!
Superb skill level and the patience of a saint!
You are an Artist! Wonderful repair and amazing home-made parts.
Watched this, mesmerised. Amazing patience and memory. I'd never be able to put all the bits back! Fascinating and entertaining.
I've never seen a person who can weave his way through problems like Mark! Ebay shows many of these units requiring new belts. That in itself is a major take on. Hats off to you from a retired technician from the USA.
