I have been following this thread with some interest. Though your amplifier has trouble, the larger problem is with communication between the helpers and the 'helpee'. I am not trying to make fun of this, but the language barrier here is incredible to me. Even for some of those who English is their first language, comments or instructions are not so clear. I can't imagine what the help of a translator app in the other cases is contributing to all of this.
In spite of what I have said, and also what I would also feel if I were you, I ask that you try to take just a couple more steps since, I am getting the feeling that you are nearer to the solution than you realize.
As a point to all here, proofreading would really help some of the gaps being made here.

btw english is not my native language. so if i don't spell something right sometime i am really sorry. but i understand everything .
Communication isn't always about spelling. It is usually proofreading what you are trying to communicate. Then when I see it going both ways, the path is more about thorns than direction.
Fortunately, your videos are a great help to those wanting to actually see how you are measuring something, so that is a plus. Also you have good ability with graphics and that too helps the communication.
I still think that you are very close to getting to something important here.

i hope so, people as for same things all the time xdd thats main issue for me. i posted my measurements and thats enough for one who knows. my profession is music so i know when i have to make a song what i have to do when customer tells me what they need. so my point is that for people who are pros my info should be enough, this amp was built by someone who is not skilled xddd
Dont get me wrong , all of you helped me and i am really thankful so i need someone to give me possible solution based on all info i provided
When you write or play music, your interpretation of it depends on the notes written on the staff. Then someone who reads music as a second language will require some patience. I am kind of joking here, but you get the idea.
I can't imagine the trouble that I would have had in your case. I learn pretty slow as it is.

Thats it xdd but this is hard for me xdd i am sure that there is something simple making this issue amp is working but i cant get full power of it xdd it should be simple. Simple for you guys xddd
@sg97, In post #44, there was a resistor that was no value reading, did you replace it?
In post #57, one of the two 220Ω resistors showed 320Ω, did you replace it?
I also noticed that when you measure the voltage in post #489, the black probe is not on the ground trace.

those wired ones are replaced with 1.5ohm that people said is ok, other resistor values you can check in piture that i provided
The resistor between the two diodes (132KΩ) definitely needs to be replaced! Please replace it with a 22-47Ω resistor and post the results.
Edit:
If you don't have a 22-47Ω resistor on hand, you can connect the two diodes together with a short wire and check the center voltage.

In post #210 OP says this 47 ohm resistor measures 46 ohms...
If, when connecting 2n3055, the output is 0.8V, then the lower transistor has opened strongly, and there is no connection with the upper side.
This means that the 2 diode circuit is broken.
We need to restore it according.
