I am selling here F-2774 Buffer Amp Board for Sansui AU-X1, complete with selector and potentiometers.

As you can see on pictures, the board are 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!

I have another one F-2774 Buffer Amp Board for AUX1, but this is just a board (without selectors and potentiometers) so it has better price.... please look here:
