    The same one i have,my brother stored it for 25 years. When i tried it the tone-arm had a loweringproblem caused by dried out grease in the relay section. In the beginning a speedvariation occured after a certain time playing records but i haven't heard that for a while. The player has a slight buzz, could it be caused by the output capacitor?

    Hey, how do you remove completely the wood trim? I am looking online for some sort of guide but cannot find anything and I need to replace my trim with a replacement

      Francisco are you on Facebook?
      If so you can contact me through Facebook Messenger it's very difficult to chit chat here
      There is also a Facebook group that relates only to Bang and Olufsen stereo equipment, tips and tricks I am quite active there. I am quite active there.
      But it will be much easier to send videos and pictures. Come on and join up. Or you can just find me on Facebook messenger... Look up my name I am the only one in the world....
      However this is the group

      @@hobonickel840 linear tracking turntables in general sound better than radial arc arm turntables.
      Because the needle is always in a perfect true stereo position. As the needle moves across the record it is always perpendicular to the groove. This way or right and left is dead center at 90° to the needle.
      Pivot arm turntables as the needle goes across the record it shifts completely so you lose your true sense of stereo. Because you are putting an arc across something that is round. So the stereo separation is never exactly right like it is with a linear tracking turntable.
      I do like the bang and olafson 4002, it is a classic piece of audio hardware that is a collector's item. There are no more being made and they are really awesome. However they require a little bit of upkeep and maintenance and then they will run forever, just like an old 1967 Corvette stingray with a 427. You're going to have to do a little maintenance on it but you have a classic there. The 4002 holds good value and I sell them for about $2,000. I also have the 4000 which is mechanically much more in-depth than the 4002. I have two of those for sale and they are going to be about $6,000 each when I completely finish rebuilding them. But there is a timeless quality about the 4000 series of turntables, they truly could be from any decade from about 1950 to 2020s..
      I would imagine that's why they are featured still to this day in New York City at the museum of modern art. I believe it is one of the only pieces of stereo equipment to remain in the museum, if you'd like one please get in touch with me.. I have been rebuilding them and currently I have about two or three ready to go for sale. It is an investment that will only go up in value.
      If you had bought a Ford mustang Boss 427 for speed when it was new in 1967. You would have paid about $5,000 for it. Currently if you can find the car, it's about $750,000. If you wait another 10 years it'll be a million and a quarter. 10 years after that it'll be a million $750,000. You just can't get them anymore so the value continues to go up...
      .. Happy New Year !!!

    You know, I've been servicing B&O for over 40 years.
    I got tired of trying to adjust the platter height like you show it here.
    Install panels, check deviation, remove panels, adjust. Absolute Sisyphean waste of time.
    I trained a tiny mouse to go inside under the platter with a pair of miniature calipers to do the work once, and right the first time.
    He also bites me if I leave bottles of liquids on my worktable, while the appliance AC is live; not to mention if I try to work while I'm hungover and burping.

      Omg .. I can't believe this... I have a little helper too but mine is a hamster, and his name is Gerald, but my problem is he's always hungover and it's hard to get him to get inside of the turntable with his little mining helmet...😂 The lazy bastard
      Here's a big trick for you, use a washcloth on the spindle and grab it with a plies and pull both upper and lower platters out of the platter bearing at the same time, without taking off your aluminum covers...
      You won't damage the spindle for the record hole, and it just makes taking the platter in and out so much more efficiently..
      Yes and Gerald taught me that .

      I found the best way to remove the platter without taking the plates off to adjust the bearing height.
      And that is to put a washcloth over the spindle and then grab it with a channel lock for a vise grip and pull the whole unit out at once adjust the bearing height and then put the platter back in and check

      Hi Nikos.
      I apply a synthetic oil which I will list in the link below. It is worth it to get a large bottle. It is a synthetic oil. So there's no water in it so it really never dries out. But the trick is is to always clean the threaded brass rod that drives the carriage about every 6 months, clean it with rubbing alcohol or turpentine, just poor turpentine on a paper towel and let the screw drag your hand down it as it spins and then go from the other side. Also taking q-tip and put it into the platter bearing and clean that out. And then literally you would need just three or four drops on the screw and in the platter bearing. And do that every 6 months and you're good to go
