Elektor Formant Modular

hi,

Hope you get on ok. If you've got most of the parts it should be ok. I'm 
building the new modules from the German book. No it has never been 
published in english. There are a couple of mistakes poping up in the new 
book. For instance the powersuppply pcb is flipped and needs rotated. But if 
you've built the old one then you wont have that problem. There are a couple 
of connection issues in the boards that I'm finding as I go through I will 
list them when I'm finished.

Just got one of my VCO's working, Adsr 1 working, LFO only one working. VCA 
and VCF to be tested once support brackets and front panel assembled.
