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).

I feel somewhat remiss in that when I made my last post I didn’t see the previous 3 posts on page 2.

Anyway, I purchased a set of Moongels yesterday and will be looking into the mentioned replacements for equipment footers. These things I will employ when I get back from a month of travel to the southwest US.

I have it on pretty good authority that Vibraplanes are the only truly legitimate isolation platform.  I think that this is confirmed by the fact that an air  based isolating platform is what is used in all real deal labs and research facilities. 
For light weight gear you can "mass load" meaning adding a steel plate or other level, stable weight to fulfill the platforms weight requirements. I have three, one exclusively for my tt, a Basis 2800. I've added a 110lb steel plate and it sounds truly awesome, much better then before I added it.

I found some scrap wood today in the house and pulled out a board which had been cut in half. It's a soft wood and lightweight.

Using 5 Moogels underneath, I swapped it with the bamboo and take a guess...my system sounds terrific. It's got a warm timbre with realistic sounding instruments. Preamp is using the Isonodes.

As a test, I used the worst DG mastered CD's I own and the music does sound natural. These are the harsh sounding, close-miked orchestra CDs and they sound quite acceptable when using this new suspension shelf. And no resonances from my rack.
So, I think I'll buy some finished wood at Lowes.
