Anyone had a Sony PS-2251 turntable

Same rules of shipping for any turntable:  Remove the platter if possible.  Remove the tonearm, if possible.  Make sure any transit screws sometimes used to immobilize a motor that might be spring-loaded, are tightened down.  Then use foam rubber, styrofoam peanuts, etc, and wrap tight.  Double-box if possible.

Great, thanks lewm, I had mistakenly gleaned that the 2251 needed extra measures outside of what you laid out. 

Appreciate the reply

I would not know whether there’s anything special about shipping a 2251. If I were you I’d download the owners manual from Vinyl Engine or some other reliable source, and read about unpacking, which is the reverse of shipping.

The 3 red screws secure the isolated hanging transformer to the under side structure once placed in their correct position.

Remove plater including the arm's rear weight and secure the arm to its at rest post  with a twist tie or elastic.

A side note, there were some version’s supplied with a multi voltage plug accessed near the transformer and  was Sony’s very first foray into DD table’s.
