Help with isolation for Linn LP12 on wood floor

Hi,

Thanks again to all members with their help with my previous hum issue. Now this system "Tubes that rock" is almost there! I moved the Turntable from the right side to the left side of the wall unit and it seems to be more acceptable to vibration and skips when someone walks by. I am not getting feedback while playing but I think it would sound better with some type of isolation device or isolation shelf etc. Unfortunately I know nothing about them. Suggestions would be appreciated. Thanks to all for your invaluable help

If you are on the ground floor, and there is a crawl space below your listening area, you may want to try reinforcing the floor joists directly under your turntable stand using blocks and wood shims between the bottom of the joists and the ground. This worked well for my LP12 in one off-grade house where I used to live.

A wall-mount may not work very well on an interior wall since interior wall frames are simply nailed to the sub-floor with no building foundation directly below as is the case with exterior walls.

I have a Thorens TD160 suspended table in my living room with a raised wood floor. I have owned the table only four weeks, so the installation is temporary. I have it on a 1940s vintage steamer trunk that is filled with probably 60 lbs of "stuff". I have the table sitting on 3/8" sorbothane feet.

There is absolutely no issue with vibration or skipping...including during moments of dancing or jumping around.

Maybe I'm just lucky with this set up.

Oh mercy - you poor people with wooden houses... I feel for you - really I do... Here in South Africa it is against the law to build a wooden structure in town. All residential housing must be from brick and concrete...

In Los Angeles, brick houses tend to fall down in earthquakes, killing people in the process. Wooden houses don't necessarily fare better, but they tend to stay together thus preventing walls from falling on top of the occupants.

Smile. A similar situation here in Silicon Valley. The fault line is within 50 miles of my house.
