Here you have a rare opportunity to buy an original Sanken Bridge Rectifier what Sansui used at low voltage power supply for example in TU-X1, AUX1 (Board F2781, D11 and D12 +/- 14V), TU919 (Board F2876, D02 - 5V, D03 – 13V) BA-F1, CA-F1 and some oothers…
Why they are rare? Because all today Bridge Rectifier has AC pins in the middle of chip, minus and plus pin on the end of chip, but Sanken RB series Bridge Rectifier has AC pins on the end of chip, minus and plus pin in the middle of chip!
Here I must say something, Sansui used Sanken Bridge Rectifier model RB-152 which is 250V RMS Max, but here I am selling model RB-151 which is 150V RMS Bridge Rectifier, all other parameters are the same, look

As I said before, those Bridge Rectifier Sansui used only at low voltage power supply (in the most cases supply with up to 25 V) so nothing would be if you replace non-working (or bad working) RB152 with new and unused genuine Sanken RB151. But if you are not sure, please write to me and I would tell you could you or could not you can replace some RB152 with my new RB151.
