Hi!
This is my first post, english is not my first language so i'll try to do my best effort!😅💪🏼
I bought a dirtbaby pcb (2016 ver.) some years ago but I've never built it until some days ago, and I'm getting trouble to get it work. When pedal is engaged, I only hear clean signal, all IC voltages seems OK, I tried with audio probe following the signal path and I think the problem maybe is in IC 2 or IC4, in IC2 I checked with the probe and I get dry signal (no delay) on pin 15 and a noisy low volume signal on pin 14 (Wich I think is the IC output because it goes to IC4), and I get no signal on IC4 input. I tried changing IC2 and IC4 and problem continues.
The only pot it seems to work is the level pot, the others don't affect the signal at all.
Seems like everything is fine but IC2 is not "delaying" I think, but I don't know what causes it. I removed some capacitors around IC2 but everything was fine.
I hope everyone could give me a hand with this, thanks in advance and any suggestion is welcome! 🙏🏼
