CV Out remains constant #205

Open jjberry opened 10 months ago

jjberry commented 10 months ago

I finished my build and did calibration, but my CV out voltage remains constant instead of the expected stepped random voltage. It varies with the position of the scale pot, but does not change with the clock. Screenshot 2023-10-30 at 6 54 15 PM The blip in the screenshot was produced manually with the scale pot.

Noise and Pulse outputs behave as expected. Screenshot 2023-10-30 at 6 53 13 PM Screenshot 2023-10-30 at 6 52 56 PM

I did have one issue during the build - I swapped the 51k resistor for the 5.1k (even after the warning in the manual). I had to pull the 51k out and may have damaged the PCB. IMG_1027 IMG_1028 IMG_1025 IMG_1026

Thanks for any help!

I ended up getting a second kit, and a new soldering iron. The second one works fine, so I will try re-soldering the first kit to see if I can get it to work.
