Discussion about the Korg PolySix synthesizer

If it ain't one thing it is another. So in starting the MG calibration I show a 1v drop but no wave. I made sure my scope was calibrated and tested on the polysix output and could see the wave form as I played some keys. resetup for the MG calibration and again just a 1v drop but it is flatlined. So I swapped the LM3600 with my other P6 to test if it was bad parts but again nothing. 

None of the MG affects the output other then the selection switch VCF/VCO/VCA.

I moved the loose blue wire to the proper spot on the PS +5v rail. If I remember correctly this LED will pulse when the MG Dial is engaged or it at least did with an old P6 I owned in the past.
