SSM 2020

[gstopp at fibermux.com]

     The SSM 2020 is a dual VCA.
     
     I've been doing some VCF research. I've got a bee up my butt about a 
     good-sounding low-pass that isn't a Moog ladder and is made from 
     easily available components, and NOT filter chips. Once again I want 
     to BREAK FREE of all dependence on SSM or CEM chips. So now I've built 
     a 4-pole low-pass using four CA3080's, as per Electronotes issue #41. 
     The circuit is identical, except that I'm using CA3140 buffers instead 
     of FETs, and a MAT-03 instead of the AD821. It's built (just finished 
     in fact) but not powered up. Maybe tomorrow...

           I was just reading the stuff going out about SSM2040
     
       filters, and was just curious, WHAT is a SSM2020?
     
        Also, does anyone have any suggestions for building a discrete
     
      VCF that is *not* the Moog Ladder or other variants of the same theme?
