Need help with Sansui 1000A phono boards

Does anyone have a component map for the phono boards in a 1000A? I need something that has the circuit boards printed out with designators on it for the parts. Also the 7 or 8 IO tabs on the bottom of the boards. What each leg is and where it goes. I could map it out the hard way but was hoping someone may have already done the hard work already. Also I am looking for a small circuit I can replace the stock circuit with. Preferably with improved performance.
Thanks for the help. It would be nice if Sansui had maps of the boards like most of the other brands do.
 
The phono section on the 1000A seems to be identical to the AU-70.
I traced the layout of the AU-70 phono board a while back - hope it's useful
