And another side :

I just check resistors and capacitor - everything is that it should be - resistors are 100k, cap - 10uf 50V, soldered well.
Every electrolytes is 25V and more
But nothing has changed - i still hear only squeak from pin 3, and voltage is still the same. :'(
Maybe, it's a power supply problem? I take it from my Univibe project - it worked there.
Now i washed my board and i will take a break for a day, until it's dry.

Here is my guts:

Hi guys!
I'm trying to make Dirtbag Deluxe on MN3005. My first attempt finished poorly as I've turned on 18 volt instead of 15. Recently, I've replaced all IC's, including MN3005, and I started to bias...
I can hear only clean signal and the volume of it changes with the Level
When I try to listen the signal from pin 3 of IC4, I hear only squeak and its intensity is changing with the lever Mod (the same situation with pin5 of IC4). I can't hear any guitar sound.
I used CD4047BE instead of CD4047BCN and this is the only difference in scheme.
What should I pay attention for? Have I got not working MN3005?
This build is real pain in ass,  I've spent more than a year doing it.
