I found this last night, the text contains a little explanation of the circuit, which is quite interesting, and there is a block diagram. Perhaps the schematic is no clearer than the other known version, I may print it tomorrow on A3 and see.
I should think a tracing might be better for a redraw.
Perhaps I won't bother!
That thing is crazy. Like the MXR Envelope Filter, but turned up to "11."
I think the bad copy makes it more intimidating. :icon_twisted:
Nah. I think it is just the poor drawing that makes it difficult. Somebody got it in their heads that drawing out the full diagram of the two channels symmetrically would somehow be "helpful". Yeah, right.
That's what happens when you try to cram a large schematic on what is essentially an 8.5" x 11" piece of paper.

I discovered a trick and made a start!
