Kenwood Super Eleven Service Manual - PLEASE!

I desperately need a service manual for a Kenwood Super Eleven Reciever. This is the first one with black face, digital meters and 7 band EQ. I have one channel that just died on me. The relay still kicks in and the other channel works perfect. I checked the fuses and all of them are good. But I think I have something wrong with the power amp driver transistors or something of that sort. I've looked everywhere and can't find the service manual anywhere for free. I may have to just buy it. Seems like everyone that has the manuals are not willing to share. I'm sure that's why they are so hard to locate. Thanks!
