Technics - SU-700 Solid state amplifier

Here I am offering a Technics amplifier.
Technics SU 700
I tested it by connecting a tuner, and since I didn't have access to the speaker, I could only connect AKG headphones, and everything worked well enough.
Please determine the rest state from the images.
So that there are no misunderstandings later.
