Hello.
Looking for opinion on combining choke loaded class A (like MoFo) with idea from TubeCad - https://www.tubecad.com/2015/11/21/Single-Ended%20Plus%20Class-C.png
Myself have to combat strong visual diffractions visions to predict it's behaviour.
Maybe someone with trained eye can point at possible pointers.
Ideally in class C operating FET would receive signal from LPF with feedback from Source of Class A operating FET equalized with array of active filtering / maybe comparing input to microphones nested around speakers (should be possible to control the gain of circuit by not applying feedback to class A FET's gate).
The goal is to extend the low frequency domain.
I am already building MoFo slowly, and will be using mixed choke (50mH iron+ 20mH air core).
I presume that they might generate some DC, would that be a strong issue for paralleled MOSFET?
What if SE MoFo is given an extra negative rail for this class C FET?
