I don't think there ever was a run of these boards, definitely not by JH. As mentioned Fonik posted a PCB image on his site and that's what I used to make mine many years ago.

Ken Stone has his own CGS version ('Twin CMOS Filter') with a fabricated PCB you can purchase.

hi there

Ken's pcb is a bit too bit for my needs, thanks tho. I also believe it needs -ve voltage?

Fonik's compact, LM13700 version would be perfect for my needs, in the single supply 9v LDB1 drum machine.

I think ill try to stripboard it. Be a challenge!

Many thanks, ben

wow. i did not get any notification for the latest posts!? sorry.

anyways, all the Jürgen Haible stuff is now in good hands. a friend of mine came to an agreement with the lawers of the haible family. so stay tuned, there will be an DIY euro version of this filter.
