[sdiy] Semi-Discrete (3046) Minimoog Oscillator Theory Of Operation?

[JR]

Hi everyone,

Does anybody know where I can find some documentation that describes
precisely (down to the individual component ideally) how the middle
style semi-discrete Minimoog oscillators work (This design:
http://www.fantasyjackpalance.com/fjp/sound/synth/synthdata/16-minimoog/002/903-osc-print-schem-below.gif)?

I've been building a clone and I've got 2 out of the 3 oscillators
working, but I don't understand the schematics well enough to use them
to debug the middle oscillator (#2).  I have kind of a general idea
how an op amp works for example, but how this collection of
transistors and op amps works together sort of eludes me (especially
the main oscillator source -- the saw -- it seems to come from the
combination of what's going on outside of the dashed lines and what's
inside them -- you don't seem to get anything if you just connect the
circuits labelled "Oscillator 1, 2 or 3" [in the dashed lines] to
power -- instead they seem to be cooperating with the left half of the
diagram to create the main saw that drives the whole circuit).

Thanks,

Joe
