CV-A track 1 not working

Hi @odevices,

The CV-A on track 1 of my ER-101 doesn’t seem to work properly. It generates the same voltage up to the 42/43 mark and then seems to jump with each unit. I looked at a previous conversation from Feb '19 and checked the DAC - this doesn’t effect the voltage when I press on it. The top solder joint (as explained in the previous conversation marked in yellow) does look a little lumpy but it’s quite hard to photograph, I can send you a picture if you want?

I could also send you a video of it in action if you like - that might explain a bit better the problem than me.

Do you have any thoughts on what it could be?

All best
