Bostwick MA-4100x

Post a good quality photo of the component side of the entire main board and the component side of any driver boards if no one can help.
Thanks, Perry. I have repaired 2 of these for an audio shop but I have been trying to include a copy of the user's manual with the repaired amp and like to have a copy of the schematics to put into my file. I was kind of shocked that I could not find ANY information on these amps.
