> 
> Back many years ago, there was an amazing phase shift module from Aries.
> Unfortunately the active component was proprietary, and potted in epoxy.
> 
> It was a four terminal device, fed the audio in antiphase at the top by a
> current source, and sinked at the bottom by a variable current sink tied to
> the control voltage.
> 
> I spent some time thinking about what could be in that module, and so many
> years later I've come up with this idea. It is an adaptation of the old Moog
> ladder.
> 
> Note that there is a continuous DC path down the ladder.
> 
> Just an idea to share, maybe somebody could try it out.
