Elektor Formant Modular

i have 3 smaller elektor formant systems saved from basements, old studios,... and i'd like to 
use them together.
can somebody help me with tuning and fixing a little? 
i can solder and have made stuff, but for this i'm looking for someone with formant 
experience.
the best would be to do this here (in ghent, belgium) but if this is not possible i can come 
over too. 
i can pay and / or trade my spare modules/printplates for help!
please let me know. best, floris
