Hi all. New Beogram owner and new to the forums. I'm setting up my Beogram TX and I noticed that the fly wheel (and subsequently the platter) is rising and falling as it rotates. My instinct is to adjust the screws that set the drive unit height, but I'm not very mechanical (and can only see two of three).
My bigger concern is that if I mark a spot on the platter, that spot will rise and fall as the platter rotates. So the platter isn't simply too low in the back and too high in the front. Will adjusting those screws address this issue or is there some other way I can level the platter and keep it from rotating like an LP with a slow warp? At present, the unit plays OK but I assume the rise and fall can't be good for the stylus.
Thanks in advance to any/all who can advise. Great source of intel here which helped me choose the Beogram TX (with an MMC 2) in the first place. Best to all.
I have the same problem with my Beogram 4500, I did adjust the three springs with no real success , I can only assume that the sub platter is warped or something, any help would be appreciated.
If the center bearing is fine and solid in place (no wobbling), the platter or subplatter (or both) are most likely warped.Perhaps one or both were dropped.

Hi Martin thanks for the reply, my center bearing does move a bit if I twist it side to side , every now and than I get a scrapping sound towards the end of the record , to cue this twisting the centre bearing seems to cure it. Still get the warped platter effect though ☹️ can't imagine anything ever been dropped ( use to belong to my late father in-law, and he wouldn't have tampered with anything.
Since you are seeing it go up and down versus simply not being level with the top plate, that indicate a problem with the sub-plater as you state it happens with the platter removed. There is that black plastic insert that could not be completely seated. If will not be the bearing or suspension as they would cause simply a fixed tilt. It has to be a rotational part based upon your description. I would remove the subplatter and examine it for lack os it being perpendicular to the shaft. You will need to download the service manual for instructions on opening it. Do not try it without reading it first.
