MS20 Filter on Stripboard

Hello friends!

I'm back with another stripboard layout, this time for the Korg MS20 type filter. I started from the most complete and up-to-date schematic i could find, which happened to be by Kassu. If you would like to save yourself some time on this build, you could buy yourself a PCB from the Kassutronics store: https://kassu2000.blogspot.com/

Kassu also reminded me that this work was based on previous contributions from René Schmitz, so please check out René's page as well. https://schmitzbits.de/

I've built two modules using this diagram. Please let me know if anything needs clarification.

One final note: Please reference the KS20 build guide on Kassutronics website for the V/Oct RV6 tuning procedure. It's about what you'd expect, but if you're new to this type thing, you can get more information from the aforementioned PDF.

UPDATE 2021-Jul-10:
Updated the pad labels and panel wiring diagram to better reflect intuitive potentiometer operation. All knobs essentially had pins 1 and 3 swapped.
