[78-L] Turntable vibration isolation

[Malcolm Rockwell]

I remember something about mercury isolation dampers fit as "feet" for a 
platform the table would rest in or on. That way the room can dance a 
jig, figuratively speaking, and the table will remain rock steady. Not 
sure about audio frequency transmission, though - if you thump the shelf 
that the platform is standing on will the sound be picked up by the 
cartridge? Maybe yes, maybe no.
