Re: LM324 AGC Issue

You have to calibrate the POTs on the top row. It’s in the notes of the build and calibration. If you did that step then something is wrong. If I recall the second pot on the top of board from the left adjusts the voltage for the LM chip. The 4v is desired voltage to power LM chip.
