I'm new to valve amps and have some questions about microphonics. Does anyone experience microphonics distortion through their guitar amplifier? Would it be due to a faulty vacuum tube or other component, and can this kind of distortion occur with other types of valve amps? Thanks for any info.

I have always assumed any microphonality to a guitar tube amp's tone would be both intentional and designed since you can't eliminate it short of moving the head into a different room than the cabinet. I always sort of thought it was a way to add some sort of additional "feedback loop" (not exactly the right wording) to sustain the sound and get more lows and mids out of it.
Not to side step the question, but everyone that has ever used a Tube amp has experienced this whether they know it or not. It might actually be responsible for it's lower order harmonic distortion. I've never seen anyone test a tube amp and the cabinets completely isolated.

I think that the designers of the amps are extremely knowledgeable and aware that they could dampen the tubes. But they choose not to. The only way I personally would do this is if I used different model tubes than they installed and microphony itself caused a horrible change.
No harm in trying it out. It is all about what you want. If it gives you s more unique sound, that is a big bonus.
