Microphonic Effects on Solid State Circuits - Microphonic Effects on Solid State Circuits

As promised some time ago, here's a little test for microphony in solid state audio circuits.

This is not presented as a case that such effects do no exist under any circumstances - it is simply a practical test that can hopefully inform further discussion.

When doing these sorts of tests I like to make the conditions as extreme as reasonably possible, on the basis that real world use is very likely to be kinder and any results can be scaled accordingly.

In this instance we are...
