Im Roberto and i'm new in this forum!
I've a new topic for all modular synth diyers - amateurs etc.
I bought a old VCO module, on the front plate is write "elektor/curtis" (see attached picture).
A cem 3340 is on-board but i dont have other infos.
The pcb is incomplete so i need schematics, bom or other details for to restore it.
Someone have infos about this module, referring elektor article, schematic, tech specs or similar.
Thank you very much!
Rob
