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).

"Geoff---When you say "I can do it cheaper and better" and "My springs are the lightest in the business", may I take that to mean you market such a product? Can you direct me to a site, or provide contact/product info?"

I've been in the business of isolation and vibration control for 20 years as well as many other things.  Currently I offer small steel springs of different spring rates for isolating anything from one pound to 250 pounds. These springs are very low profile so can even be used on submarines.  ;-)

@geoffkait , interesting.
"OUR NEW PRODUCT!! - Super compressible MINI ISOLATORS - VERY LOW RATE SPRINGS FOR ISOLATING REALLY LIGHT THINGS."

Are these springs heavy enough to stand on their own? Will a board placed on top with a component be stable?

Anything less is a lack of disclosure and doing a disservice to this community. You've been around long enough and involved in enough controversy to know better. 

It's a shame this has to be brought up again.

It's actually never been brought up before.  I thought everyone knew me.  Thanks for being Johnny on the spot, Spence.

I have several types of springs.  They should be used in sets of four or more.  They are very stable when used with the proper weight.  They are especially stable being low profile compared to larger springs I used to sell. As I said earlier the springs will isolate any component - with or without a board - weighing from 1 lb to 250 lb, depending on which spring is selected.  Obviously the heavier the component the stiffer the spring has to be since you obviously want to avoid compressing the springs to the point where the coils start to touch. If you use a board you need to add the weight of the board to the weight of the component to get total weight so I know which springs to send. For example, a preamp weighs 8 lb and the board weighs 4 lb, the total weight is 12 lb. Thus 3 or 4 of the medium stiffness springs will be appropriate for that load.
