Yes, exactly. We just assume sinusoidal drive because that's the most common
case

In order to get any semblence of efficiency, the drive waveform should
drive the stage from near-cut-off to near-saturation, somewhat like a
switch. However, depending on how hard the sinusoidal input signal drives
the "Clacc C" stage, the conduction-angle and thus the duty-cycle of the
output (before filtering) will increase or decrease, resulting in
variable output power in the load.

Who said the drive had to be sinusoidal? If the final can run almost
square wave, why can't the driver?
