Ok, episode two of my 8038 audio generator build. It powers up and oscillates, but I cannot get it to go above 350 Hz or so, and if I plug in a fine adjust pot it goes really weird, so there’s definitely some dumbassery going on here. Will update this thread when I’ve figured out what exactly 
EDIT: Found it. The connectors were mislabeled, so I was trying to dial in the full frequency range with the fine adjustment (kind of obvious in hindsight 
). There is still some weirdness near the lower end, but that’s for another day.
