Title link takes you to them.Via Mike on AH:
"Yanking a good filter from a killer synth doesn't replicate the entire experience of a killer synth. So, here's most of it.
The SH5 has a great VCF, which sits somewhere between the TB303 and IR3109. The ADSR plucks slightly harder than the Moog 911 envelope, and this helps make the filter sound even better.
The BPF is one nasty-sounding circuit. Especially in parallel with the VCF! Grind time. I believe that KGS (and associates) have done PCBs for this one.
The VCOs have several aspects of interest. They are not huge-sounding, but have great hard sync tonality, very sweet square waves, have soft sync, etc. Modular users are starting to discover that oscillators are not all alike, so these up the ante.
The ring modulator is unfortunately just a typical 1496 circuit. Drop in a vintage design and this would be one amazing synth...
So, all of the parts add up. There are a couple of PCB trace drawings, for the two oscillators, unfortunately not for the filters. I'd love to have three or more oscillator 2s with the synch functions, especially soft sync.
My System 700 schematics and PCB drawings have seemingly found another owner. Cry. I'd post them if I still had them.
(I also added the EMU lag processor dox. If you can suss the mystery components.)
To enjoy!

Its a shame so many of these he has posted are so cropped. I want a pony too. pancakes++

I cropped the ones I posted because the scanner is legal-size, and because it's more useful to DIYers to zero in on the desired circuit. Also, because my free Flickr account won't allow for large dox -and- retain legibility.
