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.

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.

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?

[@stevenlagoe7808]

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! 😁😁

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

[@adrinathegreat3095]

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

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

[@NesControl]

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]

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.

[@Knaeckebrotsaege]

@@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)

[@sw6188]

@@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.

[@spookisghostly4619]

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

[@kurthansen570]

… so I’ll need to make a new one. Always my favorite line. Great video, Marc. Please keep making them.

[@sw6188]

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.

[@juancarlossanchez118]

Tiene que ser una tarea titánica.

[@pearlvision7156]

B & O decks are rather weak as for the sound.

[@RebeccaTurner-ny1xx]

@@pearlvision7156 Yes. They look much better than they sound, and they often have operating procedures unique to B & O.

[@mrdali67]

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 🙃

[@mrdali67]

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.

[@AudioFileZ]

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.

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.

[@paulanderson7796]

@@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.
