Some years back I pruchased a Sansui G-9000. I had it cleaned up and a problem with the left channel repaired. When I got it back I hooked it up to my tape decks, turn tables, TV and it played great. The only thing I was not really satisfied with was the performance of my Graphic Equalizer. I purchased this owner's manual had poured myself a cup of coffee. The manual is well organized and written in plain language. It also contained the solution to my dissatisfaction. By using the preamp connections coupled I was able to run everything through my graphic equalizer and now enjoy the full potential of my complete system.
