Yes, it's the tubes. The plastic chassis helps a bit. Using a less sensitive amp/speaker combo will help (see the white paper on the Bottlehead Community page, near the top).
On the prototype we tried copper tape around the tube, with a pigtail to ground even. Didn't help much. I suspect that suspending the tube socket so vibrations don't reach the tube will be more useful than damping the tube envelope - but I figure, this is a really creative and experimental community, the really good ideas will come out on the forum over the next year or two.
Meanwhile, don't tap the chassis plate! :^)
