I have a pair of BeoLab 8000s that have performed well for me since about 2016. Now, one of them has developed a defect. The Line-In RCA jack has become loose and possibly has a broken connection leading to blasts of 60 Hz (mains freq.) noise at inappropriate times. My web searches lead me to think that 1) this is a common failure, and 2) I could easily fix it if I could just remove the weighted base and the aluminum cone. (There is a YouTube showing how: https://www.youtube.com/watch?v=RgeyUhknUms) But there is a brass split nut under the main nut that I cannot remove without a specialized tool. Do you know where I could source such a tool? Is it perhaps something that B&O sells? There is a B&O dealer in Boston, relatively near me, with a service shop and I have left a voicemail, but have no response yet. I'm not averse to paying for the tool or the repair, but I think shipping the speaker is impractical.
