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

@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.

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