    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:

    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.

      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! 😁😁

    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'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 🙃

    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.

    As a veteran service technician, I observed that you're not replacing the screws in their original positions within the slotted holes. In the video, you can see the wear marks indicating the screws' initial placement, but you're securing them at the end of the slots instead. This is evident when reassembling the eject mechanism arm and when fixing the tape mechanism into the chassis. This can cause alignment problems later, as seen in the eject mechanism.
