Hi everyone,
After a long time without appearing here, I return with this amplifier to dedicate a personal use.
Well, its previous owner only explained that I was broken, without giving me any further explanation.
Discarded subwoofer channel whose operation is perfect.
The front and rear channels, both have the same problem, when we act on the level of audio input, this throughout its route offers undesirable noises and clicks, and when we reach 70% or three-fourths, the sound is trimmed and if we continue to act on it, the sound disappears, and a slight hum appears.
A look at the most visible components does not offer me any determining data.
Which leads me to think of defective potentiometers, some IC of the previous circuits ....
Any ideas?

I haven't had time to look at this amplifier again until today.
Problem solved, the problem came from the input cables that were in poor condition, I tried it with new ones and it works perfectly, without any noise.
Thanks Perry for attending to me, and greetings to all!
