[78-L] Turntable vibration isolation

[Ron L'Herault]

I think the material you are looking for is Sorbothane.  You can make feet
from it and rest the turntable on them.  ISTR units with the sorbothane on
each end of springs that actually supported the TT.     An alternative, as
someone mentioned is a slab of concrete or marble.  I'll bet one can find a
marble cheese board or dough rolling board.   The trick is to cut tennis
balls in half and use the halves as "feet", under the corners of the
marble/concrete pad, on which you would place the turntable.   The design is
one I've read about for minimizing vibrations getting to scientific balances
and microscopes.

I tried a $500 power cord, but I still get vibrations!

I was around for that discussion, but kept my head down.  Seriously though,
I'm not interested in "improving the soundstage" or anything like that, but
are the products on Nauck's, KAB, or Esoteric Sound likely to help my
particular problem?  Somebody recommended concrete or marble slabs to me
off-list, but I'm not sure that's practical in my apartment.

The ceiling above me is just as creaky.  I routinely hear the upstairs
neighbors coming in from the bar at 2 AM, getting up for a midnight snack,
etc.

I'm in Atlanta, so no subway to worry about, though I do hear a freight
train off in the distance sometimes!
