Hi Yves, is it possible to run the minimoog vcf off of a +/-12V supply (for use in a Euro rack)? If so, do I need to change some of the resistor values?

I am thinking of putting the Bridechamber kit into a Euro rack. Anybody done this?

Thanks!

In another post people reports that the VCF won't self oscilate using +12-12V
I think Yves recomended some mods, but I'm not sure, do a search here,
the post will show up.
I'm off to a gig now.

Hi

If you want use it in +12V/-12V you will have to change some resistor values.

Make R24,R27 :220K; R26 : 1K, this should worlk fine (though untested !)
