Description
Power amps make loudspeakers work, and therefore they make audio work for us
in free space. Yet they’re an often-overlooked or misunderstood part of the
audio chain. We’ll explore how power amps work, what they do and don’t do, which
specs are useful and which aren’t, how a three thousand-watt amp can run on a
120V 15-ampere outlet, the interesting social structures of transistor
circuitry, and other little-known secrets and curiosities of the beasts.
