RE: linear design ...

"Going after a linear design in the first place, and understanding its behaviour w/o NFB might just be useful."

Building a standard SE console amp circuit, like the Magnavox DG-SE1 or similar, linear biasing of driver stage and finals for lowest THD% before working out the FBK network make sense because it is a traditional approach to circuit design.

DG promotes the idea of running SE finals at MAX. plate dissipation and with symmetrical clipping of the output waveforms. There is no attempt to extend tube life by reducing standing bias currents.

In the minds of the MLP designers, linear biasing and lowest possible THD% seems not to be the primary concern.
