I'd never seen one of these before so I removed it and photographed from all angles. Complicated beast, innit? There's an autoformer, three other high powered iron core inductors, two air core inductors, caps in 30, 8, 8, 2, 2, 2 values, and a resistor. There is also the zener diode protection circuit for the tweeter.
Whew. I wouldn't want to build one of these.
Don't worry Rich, I put it right back where I found it.
Note- the caps are NOT leaking. There was no leakage or corrosion detected in any of the four networks that I examined today.
