Glad I ordered spares of this design. Made a few errors building it, like installing the smd LM13700s backwards....all of them. Then forgetting to order the proper caps, have been ordered now but this proto-type got whatever caps I could find to add up to the correct values.
Once my build errors were sorted, the actual module works fine and sounds fantastic. No probs or bodges required on the PCB, tho I will change the CV input resistors on the notch filter so the CV has a greater effect.
No plans to sell these boards, only available as modules in NLC panels.
Will get some vids up soon.
