PCB Layout for Serge Triple Waveshaper ,this is the original Serge PCB that was hosted at old CGS Website ,i redraw it and built already two of these ,the only flaw is that it's bit quiet ,so i've added a Serge schematic of High Gain Amp and it suits perfect

Jurgen Haible's Morphing Programmer ,it appears to be very cool module ,and not so many people have built it ,but the idea is more then something between panner and scanner ..and it prolly is fun to play ,i have not built this so i can not confirm it's operation , however i assumed that Jurgen's drawing is correct ,here's a pcb layout if anyone wants to give it a try ,the wiring for this would be a nightmare for some ,i re-checked the layout few times and it appears to be the Jurgen's drawings ,the pcb is big 175x105mm but maybe it will fit in 5U or as standalone controller ,i intended to make a standalone controller with it ,and this fits exactly in the enclosure i intended .
wants to build the Serge Positive Slew ,to mention it's only single Positive slew ,and not dual like in original Serge ,however it's easy to make as the board is big and suitable for beginners ,not dense as in the CGS boards which i also have redrawn for this module,the board is 100x100mm ,tested and workin ,few values of resistors are not labeled but very easy to find looking at the positive slew schematic ..the resistor connected to out and pin 8 of the lower LM3900 is 820K and the resistor from neg (negative pulse out) and pin 9 is 220R ,between base of the transistor and out is 4k7,Good luck !
