    If you have it on a desk where you’re doing things that move it even a little that’s your culprit.

    Open it and check if the tubes still make good contact with the damping foam. In my case I had to press it on there a little more some years ago, but since then it seems okay.
    After using it for a longer period it may ring some more as the glue gets less sticky.

    What others said - more isolation for tubes. Sorbothane, neoprene, etc. bases help, but I've also had good luck with additional tupperware filled with bags of small-mid grain sand (from beach) IF your setup safely allows for this.

    @fp627 re "additional tupperware filled with bags of small-mid grain sand": please elaborate with 1k words ... or better yet, a picture.

    Not sure if you two are ribbing or serious but here's a quick sketch:

    Pack sand in bag tight enough that the feet won't bottom out with no sand underneath but not so tight that it can't move and absorb vibration on it's own. Table salt can also be used in place of sand.

    @fp627 Not ribbing, muchas gracias for the diagram. I seriously hadn't seen this application of sand in audio before, only weighing down speakers stands, etc. What kind of material do you use for the bags?

    Ziploc bags only b/c cheap and readily available although getting the right size bags or tupperware can be annoying. Double bag if you are worried about sand getting out. And of course be careful with anything that may rip or melt bags or otherwise cause a spillage of sand/salt.
