 Input and output signals should ideally match 100% (offset and amplitude). If not, adjust via the three trimmers until they match. Input and output signals should ideally match 100% (offset and amplitude). If not, adjust via the three trimmers until they match.
  
 +Then apply a step-function (e.g. 1V, 50% duty at 1 kHz) to the input and observe the output. If you see oscillations/harsh transients, you might have not populated capacitor C11, C14 (missed out by first JLCPCB batch -> Place 4.7 pF).
