These are typical hobby circuits from the 70s. They are also typical of cheap stereo/boombox amplifiers of the era. They would be good practice for a beginner. They're trickier than a simple gainclone 😉 . You have to have some skill to get them to work properly, unless you're lucky and it works the first time. Their performance can be optimised too. Not requiring DC precision makes design and debugging a lot simpler too.
I'd love to describe something more but do not know English. Linear and symmetrical control of the all transistors in the amplifier and speakers good works. Good amplifier strongly pumped speakers sounds of music.
Can you buy themselves an old hybrid STK080, 1983 (THD 0.0006% for Ro = 4R)? and better than the new amplifier?

I understand your concern, but NOBODY, repeat NOBODY is free to purposefully annoy, disturb, molest others, nor to abuse Forum resources and more important, contibutors who after reading one more example of this crap , feel much less inclined to help noobs, who may have mistakes in good faith.
I'll write you a short goons space: even the president has no choice, and each queen can and must use the same audio technology for schools and people, because they are not allowed to use only the space program for audio techniques.
Power transistors are poorly manufactured and DIY is a nonsense.
Enjoy yourselves, the most expensive things in my schema that can not be different.
