Thanks Paul.
I did more archeology, and in a box with the words "Vital Stuff" on
the side (from an even more ancient layer of strata) was some lovely
stuff. All the parts necessary to build 2 or 3 of these circuits. I
guess I had a clue about 10 years ago and ransacked Ace electronics in
the bay area for everything I needed.
Also in this box were some rather funky transistors. I remember
finding them there, TIS 97 and TIS 93. I think these go in Moog
circuits. At one point back then I even built the little circuit to
current match them, and had them all segregated as to who go to play
with whom.
Wish me luck, I hope this works!
