Ok, i tried but somehow it is stuck...

I am a bit afraid to damage anything to be honest...the platter on my Beogram 4500 lifted quite easily

It just binds to the subplatter - unless someone glued it  (yes, I have seen that!).
Keep lifting, using "controlled force".

The handle on the tonearm is not original.
Does the tonearm movement and lift/lower work as intended?

I can supply the correct belt.

Ok, yea it feels like its glued but since i know the pre-owner i highly doubt this...any advice on „controlled force“?  :D

Good observation skills! I built the handle myself using a very thin and light piece of metal, just so it ist easier to lift the tonearm while the record is playing. It weighs exactly 0.242g so i adjusted the weight on the tonearm. Works pretty good. Tonearm works perfectly as well.

I will send you a message regarding the tonearm!

Thank you all for your help!

So after working that thing i finally got it off! It was indeed somehow stuck/glued together with i don't know what...

I checked the service manual from the Beogram 1102, so i think the adjustment should be like this? (seen in the image attached)

Yes, thats the plan, i already got in contact with him :)

Hi,

No that is to adjust the cueing point for the 7 inch and 12-inch records.
