Service manual or parts list for Technics SA-5170

I have a Technics SA-5170 that has no output. This unit has been worked on before, and I think the values of some of the emitter resistors were replaced with incorrect values. The power transistor and 2W power transistor are shorted. I want to rebuild the power amp section and I need some parts info to insure that everything is biased correctly. Any information would help. Thanks.
