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

All advice appreciated - thank you

A disease in search of a cure!

How exactly are you hearing/determining a board inside the amp is vibrating ? If this system is on and making music (causing vibration), how would you hear that the board is moving ?

Oh please!

There are 'off the shelf parts' that are easily purchased, PCB Standoffs come with  Anti Vibration Designs. 

One of the designs discovered will be suitable for the role being selected for it.

A Part on a PCB that has a microphonic property that is audible can benefit, but it is better to treat  the Microphonic issues at the source of the noise, this has been known to remove the audible Microphonics.

Using the PCB anti vibration is not an issue, it would be 'belt and braces' if used in conjunction when treating a Microphonic issue. 

More audiophoolery! 

Measuring was easy 😊

How did you identify a problem with microvibrations?

Stillpoints once offered a product designed for this.

Goop.

A clear glue that remains very flexible.Don't need too much. Only need a few connecting dots.

You'd have to dismount from chassis, support with sorbothane or some other substance. My previous pre, Joule Electra floated board in like manner.

Not sure about tinkering inside the amp, but many people will put isolation footers under the bottom of the amp.  Might make sense to start there?
