"Poopie Bear"

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....


** That is how amps are tested for frequency response.

Output Z and speaker loading effects are a separate issue.

A triode amp can easily have low output Z across the audio band, by use of
NFB.

Fool.
