Hi, people, just made a clone from a Small Clone Chorus, used the board that is on tonepad.

But after I mounted it, unfortunately it doesn't chorus, it only acts as a bit EQ to the sound but no chorus sound, unless I move the depth pot, but just as I take my hand from the depth pot it gets no chorus sound, I tried to adjust a bit the trim, I think I get to the area that it sounds like it's starting to chorus but i play something on the guitar and there's still no chorus sound.

I made the debugging, and I think the voltages are pretty low, but I also made some parts different because I couldn't find more approximated values, like:

Condensers:
180pF ---> 200pF
0.0027uF ---> 2.2nF
0.015uF ---> 10nF
2.2uF Tantalum ---> Electrolytic

Resistors:
20K ---> 22K
180K ---> 150K


Debug:

Battery Voltage - 9.57

Battery In at PCB - 9.58

Ground at PCB - 0

D1:
Cathode - 4.19
Anode - 4.75

D2:
