Help! Schematics needed to repair my Bada Purer 3.3 SE hybrid integrated amp.

My system was sounding so wonderful before my highly modified Bada Purer 3.3 amp with Toshiba mosfets crapped out. It was modded by a highly regarded Head-Fi member. I took it to a highly touted shop in Tampa ,Pro Audio, and they believe the processor on the main board, main board is probably not replaceable, is bad and they require a schematic in order to repair it. Does anybody have schematics or any further information or ideas on this that would help with repair of this nice amp?
