OK. So a linear amp would be built with tubes to allow full flow of signal
without restriction, while an audio amp might be built with valves, because
we would want to control (restrict) the audio volume.

This thread seems to have a life of its own. From ally to this!

Amazing!

Also, why do we say tube rather than valve?

Because a tube allows a substance through it without restriction, a
valve is a device for controlling such.
