With a preamp that light, just like a small phonostage, or DAC, what-have-you, you need to be aware of not "loading" the preamp chassis with a heavy mains cable dangling from it, causing an energy path from whatever the cable is also in contact with. Again this is where those shot filled bags could be placed above and below the mains before it enters the preamp to "unload" its effect.
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. ;-) Geoff Kait machinadynamica.com |
@geoffkait Every post you write should be signed like this: "Geoff Kait machinadynamica.com" 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. Cheers, Spencer |
