So the chip is a lot longer than the original DIP-8 package of the CA3080. You can see the pinout of the LM13600 and 13700 in the first Korg MS20 article I wrote. It's just a matter of matching the inside circuitry of the LM chip with that of the CA chip, because they are basically the same. Check out the datasheet for both the chips and see how the insides are the same and compare the in and outputs etc with eachother. You'll see that the LM chips are just two CA chips in one package. I hope this answered your question.

I...Any chance of a full schematic, for one filter?<br /><br />I'm a bit confused by the diagram of how the LM13600 is meant to fit into the original CA3080 based diagram. I bought two LM13600, but now I realize I don't really understand how the circuit is supposed to be.Andyhttps://www.blogger.com/profile/09190726584414609985noreply@blogger.comtag:blogger.com,1999:blog-8559314700259794131.post-28880083265167040412020-06-15T11:18:07.397+02:002020-06-15T11:18:07.397+02:00No, you just build two of the single Korg MS-20 fi...No, you just build two of the single Korg MS-20 filters and put them behind one panel. This article just describes how you can connect them together.Eddy Bergmanhttps://www.blogger.com/profile/13286799069112368259noreply@blogger.comtag:blogger.com,1999:blog-8559314700259794131.post-82007288944339366032020-06-15T10:50:27.962+02:002020-06-15T10:50:27.962+02:00did you make a layout diagram for this one?
