Vibration Control for Lightweight Tube Components

I'm looking for suggestions to isolate a lightweight tube preamp from vibration and resonance. Not acoustic vibration, but physical vibration from the stereo rack. When I touch the shelf the preamp sits upon, the sound can be heard thru the speakers.

I am using a heavy furniture grade stereo rack for my components, all using Herbie's Tenderfeet for isolation, including my TT. The preamp only weighs 7 lbs. and has Herbie's tube dampers applied, but needs to be decoupled from the heavy wood shelf. I've tried the Tenderfeet and Vibrapods under the preamp, but neither provided isolation from vibration.

So, what are owners of lightweight tube preamps and amps using for vibration control? (there is a limited amount of space between the shelves).

"This is why it may be "ultimate" but people have to skin-the-cat for far less. And I would bet you we are getting most of what the Vp isolates (80-90%) for a fraction of the cost."

Hope springs eternal in the heart of the frugal audiophile. Springs. Get it? ;-) The article Bad Vibes! by Shannon Dickson appeared in Stereophile about the time Vibraplane came out, about 20 years ago.

I would highly recommend that you look at Solid Tech Feet of Silence or Discs of Silence. I use the Feet of Silence. I have no connection with the company- but I will say that their products are an integral part of my system. Installing the FOS was tantamount to buying a new component- they are that good, in my opinion. Go to their website and look at the test measurement results- and the results are achievable regardless of what kind of surface you put them on. 

They use the mass on springs concept that was mentioned earlier.

Sorbothane cones, or a slab of it you cut to fit, work for all my vibration issues. Google sorbothane to read about it. I got a 1/4 inch by 12 x 12 piece for about $30.00 and cut it to fit as support for all my components. My turntable would skip if I didnt approach it on cat-paw feet. Now I walk normally and detect no issues. Multiple pieces at multiple levels. Feet of the rack, suspension points for the shelf, and on the feet of the component.
