Hi,
I have a Yocto that I just finished (with a big break of 3 years ).
I have some problem with it.
On first power up and start seq immediately, on ~first Step the voices have a good volume, after, all voices volume is decreased
Bassdrum, Snare, Rimshot, claves, and handclap do not work (bassdrum ans snare have very low volume)
If i turn clockwise accent Knob, all voices volume decreased
I'm search, but is to hard to find, i have a doubt on BA6110, but I don't think this is the source of all problems.
Here are the pictures, if you see a few things : https://photos.app.goo.gl/oKS8EBhXQ4mAnXuz7
I can't find anything yet.
if there is someone who knows how to repair this machine and who could do it, PM me
Thanks.
Sound is low and some voice not working
nobody for help ?
If you have an old kit you may want to swap the IC in the accent section because some that e-lick sent were defekt.
It seems you have a lot of non working voices. For each, inspect firstly for soldering issues (there is a few spots where pads are very close but shouldn't connect..), then ICs/transistors and polarized parts orientations, then parts/values placement.
I can physically help in Switzerland, otherwise it's too complicated.

Thanks . I will test.
I made the noise modification of this site (https://masutopedals.wordpress.com/2016 ... ding-tips/), but the other mods are also to be done or this is just improvements?
There is also this site (https://www.dsl-man.de/display/DSO/Yoct ... ding+tipps) which offers mod / fix, are some of them necessary? (first fix it's ok for me)

ok, after replaced Accent CI and all re-checking, all voice work, but :
Bassdrum have only "Attack sound" (no bass) and decay knob don't work.
The handclap sound is fully saturated, BA6110 burned ?

For the clap, just change the trimmer setting maybe ? If your BA6110 was burned, I think it most likely wouldn't output any sound (but I am no expert).
For the bassdrum:
- if you have sockets, try to swap U12 with another similar IC
- check C43 value and orientation
- check R170, R164, R169, R168 (absolute) values
