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).

Tomorrow I'll play with placement of the Moongels, and I do have various pieces of wood to try.

adg101... what are the dimensions of the Daedalus DiD's, specifically the height?
I have a height issue with the large tubes now that I've added the bamboo board.

Please note for most applications small springs don't require a board of any type so that eliminates that variable.  Also, if one wishes to use a board or granite whatever, due to the nature of mass of spring operation/function the physical characteristics of the board or slab are minimized since the board or slab itself is isolated from structural vibration hence can't get too excited.

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.

lowrider57. The DiD's are 1 7/16" tall - 2" Dia.

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.
