[sdiy] RG Keen Phase Shifter Using MF10CN

[Scott Stites]

Hi All,
I've had in my possesion for quite some time a PDF file called 'PHASER.PDF'.

Basically it's a Phase Shifter designed by RG Keen that uses the MF10CN switched
capacitor filter rigged up as a couple of notch filters, rather than the normal
approach using all pass filters.

I'm just curious if someone out there in Synth-DIY land has tried this particular
circuit out, and if so, what were the results (desirable, undesirable, so-so,
great, etc.)?

I have all of the elements for it, but I thought I'd ask first before diving into
it in the future.

Thanks for any information,
Scott
