Best way to dampen a micro-vibrating Printed Circuit Board inside an amp? Thanks!

@carlsbad2 

How did you identify a problem with micro-vibrations?

@vinylfun 

Measuring was easy 😊

@vinylfun

Pray tell, how did you measure the micro-vibrations?

A question for someone to ask, who doubts PCB's pick up Vibration which can be detrimental to the Signal being generated and transferred.

Ask Audio Note why they are having PCB's produced from Panzerholz, which as a a material has the value of the intrinsic properties for Damping/Dissipation well documented.

Ask Taiko why there are components used in their Topology that are Interference Fit into a Panzerholz Periphery Ring. 

I would feel quite comfortable with the notion, both AN and Taiko are making the designs available as a result of Objective Evaluation and not the typical methodology seen on forum, which usually equates to voicing ones "Contempt Prior to Investigation"     

How did the OP determine that these mysterious "micro-vibrating circuit boards" had an impact on sound? 

I have my personal doubts and feel it's just creating another excuse for substandard music reproduction from over-engineered, high-end audio equipment.

Enjoy the music and stop being hypercritical of "ghosts" in the system that are less than a rounding error in the reproduction chain.

To OP,  However you determined this phenomenon, will you be able to tell if "the cure" works as advertised?

I would absolutely do the least intrusive remedy. Simply to ease your brain.

A healthy amount of blue tack placed strategically might be your ticket. Let us know

Or if you're all in on this...get a tube of green glue and spread it liberally on the offending board. Beware it will wander.

@pindac is correct, there are any number of companies concerned with this, I presume they did due diligence. My Joule Electra pre did this with signal board containing tube sockets, I could see how this could reduce tube microphonics.
