BGW Model 85 Help

Does anyone have a schematic for the BGW Model 85 Active Input board.
It feeds off the main power supply and appears to have dropping resistors and zener diodes to lower the voltage. The Active input board has burnt components where the power enters the board. The amp work fine, but I would like to repair the active board.
Thanks in advance!

I was able to obtain the document. Thanks.
Unfortunately, that only shows the connections to the main board.
The board with the XLR input is a separate option (the 85-01 model I believe).
The board contains circuitry and at least one IC. When I get a chance, I will pull the board and look up the IC. Perhaps the voltage specs of the IC will provide a clue.
I also have a second unit that I can look at as well. If I figure anything out,
I will post it.
