Here, you have a chance to buy NOS (never used) Rectifier Diode for Sansui amplifiers AU20000 and BA3000 and receiver  QRX-9001,  NOS (never used) model SG-5TS. It is really hard to find this type of diode, so maybe it would be the last chance to get it!!
Because it is long storage item, there are some light scratches and some discoloration, but as you can see on pictures, it is UNUSED!

Please look carefully at high resolution pictures, because they are part of description.

Feel free to email if any questions and please check mine other listing. 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. Thank you for understanding!
