thank you Guys for responce, I built another one withe one PCB and i gett the same problem i have cheked every Part witch LC meter befor soldring, only the potentionmeter P5 work , else nothing work , I have checked  the Voltage in input and output of all IC they all looks good ?  all the component is Original ,i have 10 pics of every part , there is 0 Voltage in the output of coil , i think that LF357n SMD is not good quality ;
Notice (i don't have 25k potentiometer) i have placed 50 k with another resistor to get 25 k ; i use its as Voltage divider
What else  [idiot] C10 and C5 is two of 6 nF or two of 12 nf ; that means 12 nf or 24 nf ?

the pcb looks very poor.
looks like that some of the copper tracks are broken
try a continuity test on ALL tracks first
