Sansui 9090db powers up but no sound
Before sending to service, I would make sure the pre-out/main-in jumpers are there and installed correctly. If they are missing or installed incorrectly, that will result in no sound. See lower left side of this picture, https://www.iavscanada.com/wp-content/uploads/Innovative-Audio-Sansui-9090-DB-back.jpg Also, if either of the "Tape Monitor" switches is pushed in, that will prevent anything else from playing. |
I have a Sansui 8080 and the answer about the jumpers is brilliant. The 9090db & 8080 are extremely similar. One thing that happened to mine is the selector switch for inputs had issues a few times. We are talking 30+ years ago, but I believe the tech had to re-solder the contacts back on a couple times. Also the speaker selector switch had the same issues. But as posted prior it could be a lot things. Good luck. My amp rocked my world for many years. So much so that my daughter used in in her college years in the early 2000's. -John |
