Once again I'm not talking about an OTL design.

Simply the transformer in the cathode circuit. No voltage gain. Inherently
flat frequency response ! Much more linear.


** A power triode inherently has a flat response from DC to hundreds of KHz.

With a *pure resistive* load - yes.... The impedance presented by a
transformer
loaded with a loudspeaker is *anything but* pure resistive however !

With a reactive load in the plate circuit the gain will be approx proportional
to the load Z. Hence any variation in Z leads to a variation in gain and hence
changes in the amplitude/frequncy repsonse.

That's *basic* stuff !

The same is true of transistors, just substitute the word collector for plate.
