Pio, I think circuit VX150 is fundament of your machine.

I don't know if I understand (i'm french).
You say that the HH performer is based on the diagramm of VX150

But the VX150 is an audio amp
see http://www.tv-bay.com/FORSALE/Audio/...er/112288.html

Do you know the performer amp ?

My problem is the channel 1 doesn't work and the sound is very bad

I don't know if someone else, before me, modified the wiring inside the amp, or if the problem is electronic.
That's why I search the schematics.

also the LED of channel 1 and 2 are switch on at the same time.I don't know if it's normal

Pio, if the other channel works fine, you can compare both without using circuit diagram. As a first step, you should measure operating points - DC voltages of transistors and electrolytic capacitors.
You can ask also a French forum:

thank you
I will try to analyse with your method.

Now, I will search in this french forum. Perhaps I will found it.
