Excellent...

I don't think anyone here believed you would go to London without
breadboarding it...

I'll need to try this myself. I want to try the 700 filter too.
The circuit shown looks nearly identical to the MS50 filter at Tom G's site.
Has anyone heard the MS50 low pass and 700 low pass side by side ?
Are they close ?
Is the MS50 a discrete version of the Keio IC ?
Has anyone tried the MS50 filter in a high pass configuration ?
