That looks awesome. Are you going to make it a PCB and Panel kit?

Ordered a batch of these too. @sebastian what do you want me to do with the excess? Can I offer them up for sale here at production price? Cheers for the dope panel!

Hey, yeah, of course! :slight_smile:
I think, Rich improved the board for the jacks (making the holes smaller, so you need less solder), I should change that in my repo as well…

Could send a PR I guess! Never mind, I mucked things up too much for that. But the new jack footprint is in my aoKicad repo. So is a 9 mm Alpha pot footprint that likewise uses slotted holes for the clips, but beware, that one’s terminals are numbered opposite the Alps footprint you used. (It’s actually a slightly modified version of one already in the KiCad library.)

Same, I suppose! For those in the US. Or willing to pay postage to Australia…

I finally got this hooked up yesterday, I think it’s great. Really different character than the MS-20/SKF filter I’ve had, it’s a lot “clickier”, if that makes sense. It self oscillates nicely too. I didn’t even bother matching the transistors which was probably a dumb move, but it seems like it worked out fine.
