Here is an idea that might interest some of you with turntable isolation problems: Build a box (four sides and a bottom) out of particle board or 3/4 inch plywood large enough so that your table will fit inside with a little room to spare (2" - 3") on all sides and about a foot deep. Fill the box about 3/4 full of sand (clean & dry). Have a piece of tempered glass cut so that it just fits inside the box with about 1/2" clearance on each side. Level off the sand. Place the glass on the sand. Place the turntable on the glass. Put the whole thing on a very stable surface (table, shelves, concrete blocks, etc.). Someone gave me this idea a long time ago -- I haven't tried it but it sounds interesting. Craig Dory AT&T Bell Laboratories Holmdel, NJ

The living room is a wood floor, there is a basement below. When we first moved in, we set up the turntable on furniture (e.g. bookshelf, table) that set on the (carpeted) floor. No turntable could handle it. All you had to do was walk toward it to adjust the controls or something, and the arm would hop across the record. I doubt that massive tables or bricks or anything would have worked. The entire floor goes up and down like a trampoline, causing everything to sway. We got some of those shelf rails you mount on the wall, put them up on the drywall with molly bolts, hung the shelf, and presto.... About the only thing that makes the phono skip now is slamming the front door, pounding the wall, or jumping rope.
