That is just the bias circuit in the picture, it is 6x2SC2879 amplifier
But reading all of this and researching in many different places on bias and how to implement it I'm left with a resounding question: Why isn't at least some sort of AB bias just standard equipment in all SSB capable amplifiers, even CB amps?
I'm kind of an amplifier snob in that I value a clean, low-distortion signal that doesn't splatter out of band. For me, even more than audio cleanliness it's about consideration of other operators and radio services.
I know I have a hand drawn schematic of the circuit I used. I will look for it. If you find your drawing or if someone else has it that would be cool. Just PM me.
