BeoLab 8000 - Loose RCA jack

12 replies

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=RgeyUhknUmsBut 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.

Hi,

I think that the part you are describing is a snap-ring. While there are snap ring pliers you shouldn't need anything more than your fingers or a small screw driver.  Where is it located? Stuck inside the base preventing you from removing the base, or situated inside a groove in the shaft/stem preventing the cone shaped cover from sliding off the shaft?  If the former, you should be able to work it out with a small screw driver. If the latter, you should also be able to pry it apart enough to slip it out of the groove and down the shaft to remove it.  A photo would be very helpful.  I have the oldest MKI type and it's a snap ring/split ring on the shaft just below the cone. I used a small screwdriver to separate the ends enough to slide it off. It's pretty simple.

 

Good luck,

Bill

Bill - There is a snap ring (or C ring that holds the cone on).  I think I can remove that, but I haven't gotten there yet.  I do h ave a photo that I meant to attach.  I'll figure out how to send shortly.

Here is photo of "Split Nut".  Found under the prime nut and washer that holds the weighted base.  There is also a separate weight that can be removed by loosening a large socket head screw.  But I need a tool to remove this brass nut.  Does anyone know where I can get one?

 

 

Anyone know how I can attach a photo?

I've reviewed the 8002 service manual it does show a spacer that may be the part you are referring to.  This part is not mentioned or shown in the 8000 service manual so I can't be of much help. The 8002 manual states to remove the base, remove the nut and washer and pull the base off from the bottom. I would imagine that the spacer may be fit into a groove in the shaft but I don't think it is threaded, just pushed on.  Have you tried holding the base on each side and using your thumb, push the shaft out through the top?  It may just be stuck?

Hopefully someone with the same configuration will join in to help. My 8000's don't have that part, just a nut and washer. The base comes off easily with the nut/washer removed.

Hi,

see the Wiki where Soren Mexico did two entries about uploading pics and using them in a post:

Thanks all!  Very helpful.  Here is picture.  Hope it works this time  This is what I see when I remove the nut and washer.

 

That's odd, that doesn't look like my 8000 MKI base at all.  I just checked and 8000's and 8002's use the same base.  Anyway, you should be able to remove that with a screwdriver and hammer. Carefully place the screwdriver in the slot on the left side of the shaft and drive it counterclockwise (down) with the hammer. Once it is broken free it should come out by just using the screwdriver.  Snap ring pliers will do the job more reliably, 90 degree tips would be best.  Can you post a photo that shows the complete bottom on the base. I'm not familiar with what I see in the photo.

Hi,

is it possible that you have beolab 18 bases on your 8000's?  The 18's do come with a special tool to tighten the base down.  Even so, a pair of snap ring pliers should work just fine. You could also have a good chance of loosening the special nut with a screwdriver as I mentioned in a previous post.

Good luck with this.
