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

As a debate about whether these vibrations exist at all seems to be brewing, I’ll throw out my solution:  avoid amps with printed circuit boards.

Some of the Best Tube Amp's are Point to Point Soldered, no Circuit Boards and a Schematic that is designed with a Topology for the shortest Signal Path achievable that does not generate noise.

Start adding components to such a Circuit and there is still be the likelihood Microphonics is able to be produced, hence  those in the know and experienced in addressing such matters are quite confident their methods for attaching a part to a chassis, has addressed the issue and is to be a component fitted with an Isolation as part of the mounting.

It is best to take on the idea, it is the Component that has a Microphonic not the Part that enables it to be added to the circuit.

Townshend Seismic podium are best for any damping or vibration issues but being large, they will not fit inside the amp. So you will need to move the PCB out of the amp by extending any cables attached to the PCB and lay it on the podium.

These podiums also need a minimum weight to be effective. So just add 10-20kg of weights on top of the PCB.
