Topband: how to hear through static crashes?

Best receiver I ever had for lightning static was an ancient National
NC2-40D.  Other than it wasn't that sensitive, I really think that the
signal never hit the saturation point in any of the stages, including
audio, had no transistors, and of course, it didn't have AGC for CW.  The
wider crystal filter settings seemed to work best in the QRN.  High level
audio protection was provided by (necessarily cheap) headphones whose
mechanics hard limited the amplitude.  The headphones simply could not pass
more than a certain drive. Lost those phones somewhere when I went to
college.  Wish I still had them.

The sports analog to this is usually called "winning ugly".  Hearing well
ugly.

Clues to what to do with a K3?
