R90 / IC11 not ouputting 3V / 3V

Post by nuclearsound »

Hello all, and thanks for this great place to be alive, for people like me, mounting a xoxbox. It's very nice to know many other people already have a place for this common topic.

First I'd like to mention I received a full kit from Willzyx, quickly sent, very nicely sent with all parts well organized, and full soldering manual.

Until now, all steps were ok, including all tests. I am now (only) populating my VCO and started adding a 3V supply with 2x1.5 V button batteries. Total = 2.85 V. OKish ?

When i connected the wallwart + 3V CV, my voltage was only 0.79 V on R90 and as high as 6.84 V on pin #7 of IC11 op-amp.

Is there anything that seems obvious with those figures to you ?

I'll post photos of zones if you wish me to, feel free to ask, even basic questions (I'm a basic SDIYer...)

Thanks in advance for your replies.

Antoine
