I am working on a deck of this type and the only thing that does not work is the XLR inputs which seem to go to a input board. This board is not in the regular 58 manual- no sign of it at all.
Anyone have a schematic of this board. I can guess some of the job but I like to see what I am working with.

Thanks in advance.
