Mike and list...

I built my first synth, a duplication of Moog 900 modules (the schematics
were difficult to obtain, but a friend....) in 1971. I built up 19 modules
and a Moog keyboard.  It was beautifully finished in red mahogony and
clear smoky acrylite front panels with grey knobs. It worked incredibly. 

Bob Moog taught me how to tune it up via a long-distance phone call to
upstate NY. 

Strange to hear of another early synth DIY-er!

Since I lost the synth back in the 80's when I traveled for two years
internationally, I have missed that incredible sound and facility. In
1997, I designed a set of modules around the Moog concept, and am
currently working slowly towards completion.  I can't wait to hear those
truly analog sounds again, and to link the old memories with the present!

If you Vbe-match every pair everywhere in the 904a (VCLPF) circuit, you
have the sweetest Moog LPF ever heard!

Yes, this list is very good, there are some really talented folks on here.
I've been lurking for a while now, checking things out.
