DIY Isolation Platform

What are SS couplers?

A concrete paving slab on top of a 4-6" foam slab is a remarkable isolation setup. The CD player is coupled firmly to the massive concrete block, and the compressed foam is unable to transfer any ground based vibrations to the massive concrete slab.

Oh, and it costs $10-$20. Low WAF, though. I use it under my rega planar 3 turntable with excellent results.

That should work really good w/ big isolation transformers (plus some hardwood boards & cones). I've used foam/bubble wrap with my power delivery/noise control gear successfully.

This is what I just did.Made a furniture grade box out of oak veneered 3/4" plywood.Mitre joints .Stained and laquered it by hand.Also made a cover(lid) out of same material and glued oak trims(mitred again) on the edge of all four sides.The cover is bigger than the box by 3/4" of an inch all around.On the underside of the cover piece I glued a second 3/4" plywood that is a little smaller than the inside dimensions of the box.Inside the box I laid a 14" bicycle inner tube and then placed the cover on top.So the cover is now resting on the 14'bicycle tube and my CD transport is placed on top.It's a homemade isolation platform.My box is deep so I might add a second horizontal chamber filled with about 1" of lead shot or fine sand ,plywood on top ,then 14"bicycle tube and cd transport
on top.It was a fun project with very good results.
Hope this helps and inspires you to put your tool belt on,this weekend.
