Famous in what way ? 😉
Only advantage is that you only need a single rail power supply.
On the other hand, you get two large caps in the signal path 🙄

The capacitors are *always* in the "signal" path, no matter if the transformer has a center tap. However, they may be inside or outside the global feedback loop.
In that particular schematic the capacitors will be always inside the feedback loop, no matter if ground reference is taken from capacitor mid point and feedback from the emitters or vice-versa. Some means of DC balancing is required, though.

Famous at least for the schematics... 😀ACD said:
(My face at the first look of these schematics :
) This configuration can resolve the start amp bump.

Yes, for my amplifier I need to added a small capacitor for feedbackEva said:
line. Resistor of feedback R15 is 5.6K

I try to rebuild my old amplifier100W with bootstrap and single supply. 🙂
I think the problem is that the bootstrap capacitor needs to charge/discharge at power-up/down, so you will never cure it.
