Hello: This is my first post hope some one can give advise. I bought a recapped Sansui AU-9500 unit off E-bay when it arrived it was DOA. It was blowing fuses, so I took the cover off and one of the large capacitors was loose, after moving it around it came to life. Ok now it played great for about 200 hours and a loud pop went off after taking it apart it blow the capacitors on the bottom of the left driver block. (100v 3.3uf) well I replaced them and the same thing happened all over again blew only one this time but not the fuse. can any one give this novice some suggestions where to start a diagnostic test.
