just had my 8002 serviced and set it up with my excellent Graham Slee phono pre, listening away to some of my favourite LP's yesterday night and in between tracks I can hear what sounds like a window wiper noise that you would get in your car, I then got my AKG headphones out, and I can hear it even clearer with the headphones, and even during the track, so it is there all the time throughout playing the record, its the same with every record I play, maybe scraping the platter or bearings could be causing it  ?

I read this just now on the site

https://www.beoworld.org/prod_details.asp?pid=307

Have also learned that the 8002 does not have a central bearing like belt driven players, it drives the platter not by a conventional motor, but by a unique tangential-drive system that has no moving parts and no physical contact with the turntable.

Has anyone in the past heard what I'm hearing, and if so how did you fix it,, it's driving me nuts :-)

Is the floating suspension fully free? By that I mean are all three floating suspension locking screws completely disengaged?

If they are then I would check the subplatter and make sure it isn't rubbing against something. By your description it has to be something related to the platter rotation.

The platter breaking on the Beogram 800x is electronic so if that is somehow a culprit then the fix there is electrical.

I just read Martin's post above. The sound could indeed be from the tangential drive motor. It typically advances the tonearm assembly every revolution. 
You will be able to tell more easily playing a record with the Beogram in the service position.

Is it consistent with the platter rotation?
Record scraping on the surrounding surface (suspension set too low)?

yes Dillen, but it must be scraping on two high spots, as the noise can be heard every second, so on a 33 rpm record, there must be two high spots I would think :-) 

the more I listen the more I think this is it !
