Beobuddy,

On your picture, I notice that you replaced the foam-tape placed on the sides of the column.

Are they part of the foam-kit?

If not, what did you use?

Regards,

Yann.

Correct.
I strip the BL8000's always completely. To the bare tube.
The foam tape isn't part of the foam-kit. There are 2 different types used. A 6mm and a 19mm wide foam-tape.
I use the original foam-tape used by B&O to keep the BL8000 as original as possible.

Thanks Beobuddy.

Aren't you afraid that over time the foam will disintegrate and cause a new "Foam-Rot" crisis?

I think that it will not disintegrate as the old version did. But the new type of foam isn't perfect either. From around 2003 (where the newer version was used) and upwards I also see and experience that the new foam affect circuitboards. More noticeable in BL4000's for instance.

Beobuddy,

Are you talking of the new white foam or of the foam-tape?

I’m not allowed to do it inside anymore.
I remember you said that when you did save my 8000s :-) Still very happy with them. Good to see you take such care to keep the speakers as close to original as possible.

Thanks for your great write up. I'm fixing up my BL6000 and the foam has completely fallen apart as well. I will check with my local B&O store whether I can get replacement foams (unlikely), but if not can anyone suggest what alternative foam I can use? Ie thickness, density, material, etc. Greatly appreciate your advice.

Your dealer should be to order the foam for your BL 6000 as a spare part from B&O.

In this auction can you see the number .....
