Hi to all, and thanks for you time, i come again with another pedal its funny when is mading and when sounds.
In this case this precious Arche Boost

Arche Boost - PedalPCB.com

Compare to ThorpyFX Heavy Water

The lights goes well, and get sound correct but doesnt apply boost when is switched the spdt. I put images to help

hi, anyone can helpme, i didnt get the error, if any know the values of ic plz tells me where ro find it
tks

I would start by cleaning the bottom of the board with some isopropyl alcohol(I use 91%) and a toothbrush. Some photos of the foot switch wiring and the rest of the off board stuff might help also. Have you already checked you capacitor and resistor values? They can be found here https://docs.pedalpcb.com/project/Arche-PedalPCB.pdf

Is the circled cap here a 100n? It should be a 100p like the one below. I can’t quite make out the marking but it looks like it might be marked 104.

hi @DailyDovetails ,
its marked as 104 as you said so its bad? im finding if was correct and dont see any, and i cleanned

 

[DailyDovetails]

It should be a 101 marked capacitor there. I would change it and see if it helps.

Yes, it's wrong. DD has some eagle eyes.

You can look up the capacitor code.

Basically 10 x where x is a number in this case stands for the number of zeros to follow. So 10 4 is 10 0000 or 100 000 pf or 100nf. The capacitance is 1000 times greater at that point in the circuit than intended and so that might explain your low output.

I would also follow the other advice about cleaning and reflowing solder points

You have a lot of joints that look like they have voids.. like others said looks like you need to reflow all of your joints.. heat them up and flow some more solder on them...

@DailyDovetails i've changed by 101 and works tkas to all, and @comradehoser to your xplain helps me to understand to next times.

Rad! That was all DD. Mark it as solved.
