ahhGh! tHIS WAS EXACTLy what I didnt wanna hear...I certainly did NOT 
know that the VCO needed 5v... It maybe a trivial thing (to make a 5v 
regulator) for you clever electronix wizards.. but I have no idea 
what you sayin! 

I think that has pretty much decided it for me, I HAVE to tidy up the 
current formant PSU that I have, put it in a box, sort out a wire 
distro network (currently its nailed to the side of the box, like a 
Norwegian Blue, and power is distributed to the modules via great big 
blobs of solder!!

Thanks for saving me a headache later...
