Moog 901 schematics needed

[riccardo]

Hi to you all,
a friend of mine would like to build for his personal use  a 901 osc module
as he did with other modules that we copied from my existing moog modular
(i do not have an original 901, only 920 series osc)
He needs the schematics.
Please contact me privately if you like to help...............
ciao

P.S. If i can remember well there should be some CA3019 involved (or they
are on the 901 a/b), I wonder about pitch drifting of these units.
