Here, you have a chance to buy used DOLBY Rec Level / Play Cal potentiometers for Sansui 9090DB, in very good condition. It is really hard to find this type of potentiometers, and as I can see, nothing has broken, nothing has missing, but I am selling it as untested part. It coming with board F-2694.
Long time ago, they were removed from working unit (but damaged during shipping), and I was keeping them as spare parts, but now I decided to sell them....
Please look carefully at high resolution pictures, because they are part of description.
Installation should be done by qualified technician only, because it is not simple to do that! It is highly recommended to do that in some qualified service.
Please note, I cannot accept return or refund for this item once when that item will be shipped to you.
