SOLVED Deadend FX Mangel Wurzel No chorusing (Ibanez RC99 Rotary Chorus clone)

[Fontelroy]

howdy folks, I'm having issues with a build, it's the bbd chorus from deadend fx. Here's the build doc link for those interested - https://drive.google.com/file/d/1OpvxwDCM6n1V6RT3K5LvCE-sm3y7ayhj/view?usp=sharing
The issue is I'm getting no chorusing and no reading from the pad used to dial in the clock with the trimmer
a few things to note:

• I'm using JRC4558 ic till the ones called for in the BOM get to me as I had to Ebay them, since the circuit is passing signal I assume the 4558's still work but could the chorus really on the uPC4570's called for in the build docs?
• I accidentally soldered a red wire to ground and didn't realize it till i had connected the two board so i just rolled with it

(pls excuse the messy desk)

do you have another circuit that you could test your clock and BBD chips in just to make sure they are good? And since it is always a good practice, have you audio probed through to the BBD to make sure there is signal reaching it?

 

[Fontelroy]

yes, they are working I pulled some out of the madbean pearl flanger project i made a while back, I'm currently using an audio probe and have traced the signal as far as the bbd's tho and it stops there so something is up with that area of the circuit
Here's the voltages:
IC5 - 3207
1 - 0.1mv
2 - 3.0v
3 - 5.7v
4 - 6.7v
5 - 7.23v
6 - 3.3v
7 - 7.35v
8 - 7.81v
IC6 - 3102
1 - 7.17v
2 - 3.1v
3 - 0.1mv
4 - 3.14v
5 - 6.6v
7 - 330mv
8 - 6.8v

Holy frijole folks, I warmed up a suspicious looking solder pad on IC5's socket and we're in business. My basement is chorus city!

Congrats!, See how much more space you can get between the 2 boards before it hits the Lid!!

 

[Fontelroy]

Hold the fort again

 

[Fontelroy]

No chorusing on output A just B and I believe it should be both but gonna check with the pedal this is a clone of

 

[Fontelroy]

Okay that’s fixed, we’re good for the moment, now I just have to sandwich this beast back together

 

[Fontelroy]

Thanks for all the help and suggestions folks!

 

[Fontelroy]

kinda interest sound wise, gonna have to make sure to dial it in again now that stuff is working right but right now I think I like it better in mono, it seems to have more character that way -

Sounds nice !

The Mix label is slightly unsticked in the top right corner ?

That's -150 pts, i am sorry.
