Transistor output stages?

One question; why the predominance of a multitude of bandpass
filters on the output of TXs? Why not a tuned circuit, along the
lines of valve PA stages, once the impedance level were to be raised?
A bandpass filter IS a tuned ciruit and there is usually more than
one since a single, effective filter that covers 160 to 10 meters
is very difficult, if not impossible, with LC circuits to achieve.
