I don't want to say but it seems to me there is a clear error in the wiring diagram: tr10 should be an NPN instead of PNP.

Hi Piero, yes the scheme is wrong, tr8, tr9 and tr10 are all 3 of the NPNs, I also wrote it in 3D www.juzaphoto.com/topic2.php?l=it&t=4973071 you want to participate you are welcome.
Thank you.

Ah, of course. I didn't sleep at night for NPNs! But what is it? :-D

It's
very concise, it's fine to start, then you go on more deeply, but you weren't enrolled in electronic engineering? :-D

Good memory! Exactly, I was registered! After a year and two exams (drawing and chemistry) I understood very little, but one thing I understood well and that is that it was not for me and I landed in another faculty that, in theory, I should not have liked and that instead, was the right thing for me.

You got the beginnings wrong, you should have given mathematical analysis first, then geometry and algebra, as I did :-D
In the official study plan of the specialization there was an unspecified philosophy of systems... ELIMINATED a priori, in favor of physics IV 8-)

I struggled to recognize the mistake: it was clear (except for me) that analysis and geometry were incomprehensible to me. Better something moderately scientific combined with the possibility of relating to people and organizational skills ;-)

Oh God, moderately scientific medicine, you agree with the no vax and the like :-D
Even with electrical engineering and electronics you have the opportunity to relate to people, you and I for example communicate through them, I understand your point of view, many don't like mathematics, but only because they don't understand the poetry, after all, if you think about it, everything that surrounds us is mathematics, from the motion of the planets to musical notes, just fall in love with it, then it does everything.
