I finally find my mistake, after checking all the resistors R23;24;25;26 were 330K instead of 330R.....I checked TR04,08, D02 and TR03,07, D01 they are all good KSC992 ECB in right orientation, anyway i change D01 and D02 with new paire of 1N4148.
For the transistor i put the old one 2SA750 (TR07,08) and 2SA726(TR03,04).
Powered on the amplifier, everythings good and this time the DC offset doesn't move when i crank up the volume pot!!
I put on all the cover and try to play a song but this time no sound.......
mesure the voltage it's better but not enought apparently.... send a picture of mesurement
TR09,10,11,12 are KSC1845
TR01,02,05,06,13,14 are KSC992
Now TR03,04 are 2SA726
TR07,08 are 2SA750
Now with the right resistors everything work perfectly!
Thanks to all guys who helped me
The 717 are back to life
