Amazing Mk IV Crossover Diagram

Does anybody out there have a circuit diagram for the Mk IV amazings.
I recently acquired the service manual for the amazing line, but it only covered up to the Platinums. I would very much appreciate if someone can email me the circuit or point me out to where I can obtain it.

Thanks in advance

PS I contacted Carver service and they said they MIGHT have the information, but that was several weeks ago...not much hope

Just to let everyone know, I was able to obtain the schematic for the Mk IV crossovers from Carver support. Carver support (through Sunfire) are actually extremely helpful and curteous, and would urge anyone to give them a try and also to be a little more patient than I, for they will come through in the end.
