Here you have a chance to buy very rare electronic board for Sansui amplifier model AU-X1; F-2819 Flat Amp Circuit Board with original volume potentiometer.
As you can see on pictures, the board is complete and undamaged, but because it is vintage electronic used parts, I am selling it as untested, so I cannot accept return or refund for this item once when that item will be shipped to you.
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!
