With and without C26 /C9 capacitors.class AB+С . Is there a difference ? The AB+C mode is specially taken for the purity of the experiment, when the output transistors are closed.
In the composite, the level of distortion is minimal,I specifically took a simplified basic version for better visibility.

>at 100Hz 36Vpp 8R 0.8A cross-conduction. Who thinks it's okay ?
What is max cross-conduction that would be acceptable/good?

IMHO, for true Class-B, almost zero, 0-100kHz at least
for Class-AB, the idle bias current, 0-100kHz at least

Everything determines the spectrum of distortion and the rate of voltage rise . Communication distortion is very good at suppressing oos .The rest is from the evil one
10hertz C9-100mk/100u. 1500mV input. Rated power mode
By the way, these capacitors С9/С26 eliminate the possibility of a through current VC .

in general, the circuit is not very stable;
when C5 is > 330p and C10 is removed oscillation occurs on square waves

Let's move on to the composite version.Also, the operating mode of the amplifier is pure class B . R2 simulation of the DC voltage adjustment circuit at the output of the amplifier. The clip at 1kHz and 20khz is clean, good limitation .
