U67 de-emphasis network

[GeorgeToledo]

I know this would be a form of distortion of course, but I mention it becuase of reading various comments / threads / info discussing the nasty hard clip various mics have internally, like the 87AI... and this got me thinking about THIS as a way around that.

Much of the objectionable sound from U87AI doesn’t come from clipping the FET, it comes from clipping the output transformer. It is worth engaging the pad whenever there is even a chance of it being needed.
