[sdiy] Good 24db/oct HP-LP-BP-Notch.. Enhanced Moog 904c possible solution..

[Jean-Pierre Desrochers]

Here is a modified Moog 904C filter coupler schematic
to accomodate simultaneous 904A lowpass, 904B highpass circuitries
and added bandpass + band-reject(notch) all simultaneously.
(4 filter outputs). As a first throw I'm sure I missed something
in the design.. Please let me know if you finde something obviously
not working..
