The confusing mist slowly drifts away.
OK, it looks like I called them NKK switches in my original post, but from the Mouser part numbers they are actually C&K switches, as we have recently discussed.
It also looks like the Mouser part number for the Dress Nut has also changed (the original part numbers came of my Mouser invoice). The correct part number for the Dress Nut is 611-702501201.
Time to light a fire of clarity and apology to keep the confusing mists at bay.
Also time to go and edit a few earlier confusing posts.

Oh, don't worry, I'm just happy about the quick answer. Thanks for clearing things up!

I'm a little bit confused about the wiring of the dual mixer / dual VCA.
I understand that both CGS64 boards are used for the wiring of each dual module but I can only see one output on each board, in the mixer section.
Where should I wire the IN and OUT jacks for the Dual VCA?
Any help would be greatly appreciated! |

It's because you need 2 pcbs!

two pcbs for each dual module? so four CGS64's in total? i thought that each PCB did double duty.  |

Which panel are you making? I thought the dual mixer would be done by 2 cgs04 boards.
Ken stone lists the pcbs required here:

check ken's Best Of page (http://www.cgs.synth.net/pcb/bestofcgs.html), all will be revealed...

i'm currently wiring the voice panel B (#3 pictured at the top of the thread). It's not listed on the linked page. The pcb's were ordered quite a while ago and I thought ken sent me all I needed (which he may have). I've been searching through the threads for a while now but haven't found anything conclusive.
I have two CGS64 and thought that it was a split VCA/Mixer and that the dual mixer used one half of each pcb and the dual VCA used the other. |

CGS64 is just a VCA. It has integral mixers, but they are part of the VCA, not for external use. The split down the center of the board is merely so those Euro guys can fold the thing so it fits behind their vertically challenged panels.
The dual mixer is the CGS81, and that IS two mixer circuits on one board.

Ahh makes much more sense now. I'll be ordering more boards in the next month for the other panels and I'll get the mixer pcb then.
Thanks for clearing that up. |

Hey everyone!
I'm looking for some info on wiring the Pulse divider and Boolean logic board on the best of cgs swamp panel. (wiring the pec to the panel components) Can't seem to find one on Ken stones Cgs site, seems to be for the other two boards though.
Any help would be awesome,
Matt.  |

That one is pretty straight forward. Just wire the appropriate jacks to the specific pads labeled on the board. You can ignore the ground connection since you are using banana's. LA and LC are for LED Anode and Cathode and can be ignored. You can also ignore the RSB pad because it looks like there is no RESET button on the panel. Looks like you need to wire up only one of the inverters.

Looks like no reset included on the panel either, so ignore RST. Input jack to CLK.

| im almost finished with the best of cgs b. i have only 4 more things to wire up and was hoping someone could help me out. on the daul mixer where can i wire the aux in to? also on the wave multipliers bottom section, where do i wire the in and its corresponding pot? i looked at the sketch above and was unsure what the pci or dci was. this was my first build ever. got to say it was a blast and will be doing more and learning as i move forward into this beautiful world of crazzyness. |

| I'm thinking of using blue LEDs on my BOG, MARSH, and SWAMP. (My MU system is mostly red & green + my Synthasystem is all yellow, so... variety!). Figuring out the RLED values on most things is fine, since the LEDs either have their own buffer, or share a buffer with a gate output in parallel. The CGS Programmer, however, has the LEDs in series with the outputs, so there's no obvious RLED... how would/should one modify the circuit? |

On the solder side of the board, cut the track from the cathode of the LED. Link the 680R to the track that goes to the anode of the LED.
Add RLED between the cathode of the LED and the nearby 0V track.
