The black arrow is ground and your black lead should connect to that.
The red arrow is where your red lead shoud measure.
Meter on DC voltage.

its 0.7v between bases of both transistors white wire between collectors is 28v between emitters is 07v
This voltage is correct.
Please clarify:
The white wires goes to?
The red wires goes to?
The blue wires go to?
i hope so. i will not spand a lot of time on this in the future i am waiting for possible solution i mean i measured everything provided all info
Do 330 Ohm resistors get hot?
It is necessary to have voltages relative to ground on the legs of small transistors.

Sometimes a little joke with no harm intended is appropriate:

guys i cant read this scematic btw use this one to tell me to measure thing i understand this better 😀 btw when i adjust trim now to the left i get a bit moe volume bulb is not lit even amp is on max, but still a distortion. when i did that with the trim collector voltage increases to a 30v
The fact is that if you change both 2n3055, the amplifier will still not work correctly.
There is one more error that needs to be found.
After this, the trimmer will start working, with which you can set the middle point at the output.
Only then will it be possible to connect 2n3055 and get an output power of 50 W.
