Hello everyone, I am trying to repair an Apple II clone PSU from the 1980s. I have a shortened transistor, which reads "D471C Y-3C5". Attached are photos of its location on the PSU board. I was unable to identify it online. I want to find an equivalent part. I would appreciate your help in identifying and finding an equivalent. Thank you very much in advance, Joe |

Normally with a marking like that you put '2S' in front, so that would be 2SD471C. |

Thank you very much for your help. I replaced it with a BC639 and now it is working. Now the issue is with the motherboard, but I guess it's a question better suited for an Apple clone forum :) Thanks again, much appreciated Joe |
