class b power amp, initially i used a transformer with center tap but it doesn't work. I replaced it with two simple transformers. The 555 thing is just to get attention

What is the purpose of using the 1.5k ohm resistor and the 50uF capacitor on between the directly coupled CE stage and the Darlington push pull amp stage? A single cap can work, right? And what is the purpose of the grounded RC network consisting of the 1M ohm resistor and the 100uF capacitor? Nice circuit anyway.

First ... to limit the current at the Darlington base and avoid saturation, it should not have been necessary in principle. second ... it only served as a monitor to visualize the ac voltage to the ground, forget to remove it.

Thanks. I would use a sziklai centre tapped driving stage as Idk how this driving stage works :D
