Crossover Schematic for Altec Stonehenge III (3577A)?

Does anyone have a schematic for the Altec Stonehenge III speaker? The crossover is labeled 3577A.

I can find almost every other version of the Altec 604-based systems- but not this one (604-8G).

Got a pair of Stonehenge III crossovers here, and before I tear them apart, I wanted to see what, if any, of the original coils I could reuse in a Markwart design... that may be where we're going here...

Regards,
Gordon.

That's exactly what I needed, thanks!

Unfortunately, looks like really nothing but the L-pad carries over to the Markwart 604-8G crossover. :(

Regards,
Gordon.
