The whole pre amp schematic doesnt work cant adjust anything only input audio goes throught the schematic . I have taken the schematic to two pieces the preamp and the amp . Thanks a lot for help
 
I guess you have a headphone, no?
Do you have a resistor with a value around 2KOhm?

Could you please post a photo of the board?

The way to proceed is to put power on, without any input signal, and measure the voltage on all LM1036 pins from ground.
Thus, please connect the black wire of your multimeter to pin 10 and measure in turn with the red wire the voltages on all other pins:

Pin 1: xxV
Pin 2: yyV
Pin 3: zzV
etc.
