NOTE: The version 1 (this build) board labeled MAIN1 has a misprint on the orientation of transistor Q5. I spoke with Feedback Mods and he sent me the correction, I point out what needs to be done twice in this video, or ho to the chapter marker listed below.

I also pasted the calibration instructions under the chapter list.
A multi-wave, multi output LFO. A somewhat involved build, since it’s a stack of three circuit boards, but not too difficult, just a lot to do.

And with the transistor in the right orientation it works just fine. A handy expansion LFO.
