Sansui TU-9500. No sound from output.

Hello. I am new here and just bought a Sansui AU-9500 and TU-9500 Tuner. I have no sound from output but have sound from Multipath output on tuner. Any Help??
Make sure the tape monitor switch is off and you have selected the correct input and have the speaker selector swich in the right place. There are a lot of knobs on this series of Sansui which can be confusing. good sound though.
Thanks for your reply,Ya bunches of knobs and switches there are but they were where they should of been but no sound.I just took it up to be looked at< hopefully they can figure it out. Super nice sound, Clean and smooth with my Cd player.
