i finnish try building the drone lab ver.s but i found a few things that made me confused.
1.for the distortion i dont get the fx... very low effect, than i check again the PCB no wrong ... and i tried again but i stiil get the low distorstion..

2. the 40106 overheat... it`s true..? i found many article, if we used 3- 4 gate osc the IC`s will overheat....
