Adjust the nut on top of the bearing so that there is 13 mm between the platter and the detector arm. This should be done with the transit screws locked.

Maybe not entirely - it looks like the platter should be moved a little to the right. I don't know how to fix it :-(

I already did that, and it's not because the belt is touching anything. It just vibrates a lot on the right side to the motor, coming from the platter it seems. However the belt is absolutely on the middle of the motor pulley.

It looks like it operates normally. However, I have a small belt problem. My belt seems to run very unstable on the side to the right of the motor but only in 33 rpm mode and it creates quite a bit of noise. Any suggestions? It seems that if I pull the floating suspension away from me that it is more stable.

He is apparantly sending them to Axel in Germany which is a good thing, I guess

Maybe it's a blown fuse? They are placed under the greyish plastic cover in the left upper corner.

The distance between the detector arm and the platter is supposed to be 13 mm but on mine it's 15 mm. I can't seem to loosen the nut as described in the service manual. Any tricks? Edit: Fixed! I didn't know the small adjustment screws in the nut bearing should be loose first.

Here is a small video recorded on my iPhone of my Beogram 4000. It's not completely silent as you may hear. The big click is when the electronic switches from 45 rpm to 33 rpm - some sort of relay I guess. The carriage noise which you may not hear is probably due to the carriage motor's wheel not being completely centered (it wobbles a little

So how do you clean them up?

I can't resist a good deal though I don't actually have space for it, e.g. I currently have a Beomaster 2000 and a Beogram 1800 (without cartridge) up for sale if anybody is interested. They both look very nice.
