Of course if you could get the temperature low enough you could use a
superconducting magnet and lose no power so no stray fields.

Only 12W of power consumption and the TT floats & rotates 50mm above

If they can do it with trains, a turntable shouldn't be that difficult.



** Answers nothing.

When you take into account the puny power consumption, 50mm of lift that
disappears when the power goes off PLUS and that a magnetic phono PU must
not be upset by strong or rapidly varying mag fields - it looks an
impossible task.

But pictures like the ones I linked don't lie.


One of the things I learnt early on was that pictures nearly always lie
:-)
