> jiggling the filament because of the tubes coupling to the preamp socket and it's coupling to the PCB, etc., and a tube damper surely couldn't impact that.

Surely it could. Acoustic sounds couple to the glass and the board. Changing the properties of the glass (which is a good stiff resonator) would change the vibrations of the tube-holder-board-filament-electrode system.

I would take the empirical experience over decades of people damping microphonics and out of control feedback howl with tube dampers.
