The Beogram 5500 platter would have to be taken off, and some protection against arm rolling should be inserted at the arm slot in the back. Ship the stylus seperately in a safe box.
You should also take some precautions when shipping the Beocenter 9000. The lower glass panel is known to loosen under transit, as it's just attached with double-sided tape. It it loosens, it will scratch the surface and self-destruct in small fragments of glass. See this video as a scenario of the damage done when shipping one of these wrong: http://www.youtube.com/watch?v=e3KxGmcpRZo
