tt isolation help

That is where you need to do the calculations. How much weight you have and how many springs you want to use. How can I be specific for someone else's system? Maybe the OP will want to place the turntable on a platform and then on springs. Then it will change some more. I am not adverse to be emailed for specifics. If I have the time I will gladly help.

Here's an example of a spring based platform. I know a couple of people who use them for their turn tables and like the effects:

Clio09,

That is my platform. I am recommending a much simpler approach which is to place springs directly under the table. Never tried it but I am sure it can be done. Very inexpensive to try considering my guess that the Rega doesn't weigh much.

SYMPOSIUM or SRA SILENT RUNNING im using SYMPOSIUM ULRA WITH RAVEN AC1 works great.

Trip, The springs are McMaster-Carr P/N 96485K125. They are 1-15/16”D x 4”L and use .148” diameter wire ground flat at the ends. They compress 23.7lbs/inch, up to a total deflection of 2.88”. So a 50lb load compresses each spring about half way down and leaves .88” of unused travel before the spring binds. I use six of these underneath a heavy sandbox. The springs can be moved around to level the TT.
