I built the MS20 OTA version of the filter at the weekend - it certainly has
the right type of sound.
I should get the MS50 diode ring done soon, and I'll be borrowing my friends
Mini 700 to compare the three directly.
If they all sound pretty close I suspect I'll stick with the OTA design -
it's very simple, and cheap.

Is there a copy of the original MS50 schematics online somewhere ?
I only have Tom's schematic - has this been modified much from the original
?
