Need MFA Magus B pre-amp schematic


I lost the schematic that came with the manufacturer's manual. After I modified preamp, it has some problems (it's my own fault; none of MFA). Can someone find me the schematic, please? (I couldn't find it from the net.)

Hi Ahdioohiles,
I need a schematic for a Magus A-2 pre-amp.
Please let me know if anyone has it.
