Need schematic for Yamaha MM30 Mixer

Need schematic for Yamaha MM30 Mixer
I picked up one of these on the weekend, and it suffers from a few shortcomings. It's a 4 input mixer, w/EQ, pan, and delay. There is a MN3008 delay chip on board, and a NE571, which I assume is for keeping the delay section clean. The MN3008 should be able to deliver about 100msec of decent delay but the delay time and recirculation is fixed. If you have or know where I could get a schematic for this unit (the board, not the chip) I'd be appreciative.
