That's a nice collection and I recognize some of them. I have a small collection of big bottles myself. Perhaps the rarest is an Eimac 4-750A tetrode. A prototype that was never produced. The only other one I know of is owned by a friend in upstate New York. My biggest, a 24" tall triode type E4000/10,000 (sorry, no camera at the moment)
Was thinking the same thing about earthquakes...!
Or for that matter, just one inadvertent nudge. Likely his Great Dane lives in *another* room.
I like the spring mounted tube in its shipping container!

He must be the European equivalent of Ludwell Sibley (also of the TCA), who is probably THE authority on vacuum tube history here in the US. Had a chance to speak with him at the CC-AWA Spring Meet in Charlotte a few years back. He's a real gentleman, and has probably forgotten more hollow-state knowledge than I'll ever acquire!😎
WOW!!
My own collection suddently went from huge to small and my odd tubes are suddenly not that odd anymore.
It seems like it's mostly rectifiers, photomultipliers and transmittertubes on the shelfs.
