Onix A-2150 Schematics

Does anyone know where I could get a copy of the schematics for the Onix A-2150 power amp? The remote power transformer (1.5" wide x 1" deep x 2" high) is shot and I need to know the output specs in order to look for a replacement. All suggestions appreciated.
This is a add-on to my initial post. The markings on the transformer are: 29-2347-2 (top) and 9750 (bottom). Any idea what these might mean?
The Onix sq is superb, and i believe it was made on taiwan.

Couldn't find much info on it.

Lets Hope a guy who knows something can help.
