    SANSUI AU-517 Recap & Restoration?

    Hey Sansui fans, thanks for reading. Recently my (cherished) Sansui AU-517 starting going out in the right channel. Thanks to Audiokarma I figured out it was a dirty switch that separates/connects the power and pre amps. Cleaned with Deoxit and problem solved. By passed switch with Audioquest...
