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).

Thanks adg101, some good ideas. The bamboo might be too stiff with 6 Moongels.
I'll also try them under the stock feet. They are an amazing invention; when I was playing drums, all we had was duct tape and a wad of paper towel on the skins.

And I have always placed Herbie's tube dampers at the upper third near the top of the plates.

Lowrider57, when you tried the Isonodes on the pine shelf and got the warmer and lusher presentation, what did they come in contact with? The component feet or the chassis?

Ha... another drummer. 

The myrtle wood blocks work really good and I too use them under most of my gear instead of the stock feet; use three per. I use the stock feet on my table and my preamp I run three Daedalus DiD's. All equipment sits on bamboo w/ the moongels except my amp as it weighs too much for the gels... it also has two stacks off three of the wood blocks. I have to stack them on the amp because the stock feet are tall. I use Ayre myrtle blocks which are the same as the Cardas brand.

The Daedalus DiD's are remarkable and I'll be getting a set for my cd and amp next. The wood blocks are very good but not even close to the DiD's. If you get a chance to try the DiD's you'll be hooked.

@bpoletti, no I haven't.

@r_f_sayles, the Isonodes are adhered to the bottom of the chassis.
Let me clarify this issue; my system has always had lush, warm sonics using a preamp on the pine shelf. With the new lightweight preamp, it still had the same timbre (due to tube selection), but suffered from resonances thru the shelf.
I tried Herbie's, Vibrapods, and now Isonodes; all kept the warm sonic signature, but the Isonodes provided greater detail.

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.
