Hi Ken
I've moved on to the SPAN trimmer.
One of the VCO's is adjusting fine with 1V input on the 1V/Oct input. Exactly an octave when CV removed.
Under the same input conditions , the second VCO is not adjusting beyond one semitone short of a full octave ; no matter what i do with the SPAN trimmer.
Any advice on where to troubleshoot this one ?

Hi Ken
I'm calibrating some CGS48 VCO's and i need to know what position to have the knobs in to adjust the ZERO trimmer.
I have the 'Tune' knob at 12 o'clock.
Does the position of the 'Frequency' Knob have any bearing on the calibration process ?
Should it be at 12 o'clock too ?
