An article about the history of mic preamplification (

Just stumbled onto this, nicely written IMO! Not only does it deal with mic preamplification, but also goes into detail about aspects of noise and audio engineering principles, but does so in a quite entertaining way.

my fave quote:
”…If all that junk infects our mic amp and gets amplified 3000 times as well, then we may as well call off the session and spend the night drinking.”
