Hi! I am looking for a schematic for a Peavey 260c module from a XR-500 mixer amp. I have a set of Peavey schematics that includes the 260c but this board is different from any of them. The board has the numbers: 260c, 51981 and 99009072 on the underside. It is different from the others I can find in that it has 3 TO-92's right by the TL084. It closely resembles the 260d '81 schematic other than that. Thanks!
