Of course a PCB can vibrate. Question is, if a fuse can do it? And if so, will the other sources of vibration overwhelm the fuses contribution? Will the multiple resonant modes of all the stuff attached and hung from a board not damp this whole system?
Now, yes everything vibrates and so what? TTs are vulnerable, of course, as are tubes. In both cases a clear feedback loop exists. A TT cart is designed to take very low level vibrations, connect to a pretty hi-gain circuit and put the result to the speaker.
Racks are well developed for seismic events. However, if you believe that fuse vibrations to the board (!) have an effect, than surely airborn vibes have an effect as well, and when the sytem is played loudly, will have more effect than a fuse. After all, the fuses contribution will be based on the mass of the wire, the amount of force it can exert and the frequency. I don't know what the fusing wire is made from....magnetic or not? But certainly all will agree that the amount of force a vibrating fuse wire can contribute is MINUTE a best.
I have yet to see a 'soundproof' rack which would be the next logical development.
And while we're talkin' vibes, how do you isolate your system from the Schumann resonance? I think that is somewhat <=to 8hz.
If someone wants to loan me a scope, I'll run whatever test I can devise and not only put the data up for review, but certainly remain open to experiments to run..
I asked for a used Tektronix for my birthday, but am not holding my breath.
Too much is never enough
