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

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.

Excellent!  

This is the sort of logical, fail proof, easy to do fix I was looking for!  

Thank you 😊

@OP. Fill the amp with a plastic bag full of lead shot.

The best answer yet. After filling with lead shot, chuck it all in the sea gangster style. That’s the best way to get rid of problems.
