Tim,

excellent work - though I did not yet read and understand everything.

To speak the truth the A-106-1 was designed more by trial and error without
that terrific theoretical background.

If the results of the second version of the MS20 filter are promising we may
consider an A-106-2 provided that you give us the permission and no
copyrights are affected. Even if you find out an improvement of the A-106-1
of course I'm interested.

Best wishes
Dieter Doepfer
