Yes, the γ3 can drive the β24 directly, and a few people are running this configuration (but for speakers).

Aah . . . if only I'd read this thread earlier . . .
Makes my other posting largely redundant.
Oops.

Begs another question, for a 4th variant, class AB β24, perhars 1/2 power at 80w?

Kind regards
Scotty

This variant is just an example, and a practical target for people to build.

Since a linear amplifier's output power is directly proportional to its supply voltage, you can work out a β24 with power output anywhere between 40W and 170W by setting its rail voltage appropriately and making a few other adjustments.

Hi Ti,

if I want to have "standard" voltage gain 20 for low-pow B24, which parts can stay unchanged? R2, R4, C1 and C2?

Regards.
