Sherwood rv-8070r transistor help (sanken)

sketchone · 8th May 2011, 01:25 PM

Hi, my Sherwood RV-8070r decided to die on me recently and upon opening it up and having a dig around i found that one of the transistors had melted.

Im struggling to find a replacement so far.

The transistor is a Sanken 2SC2921 and it has the letters and numbers - 74p at the bottom

Iv managed to find this Sanken Sanken Transistor Mt200 160v 15A 150w BCE | SANKEN | Sanken but as you can see from the pic it has the numbers and letters 82p

Can anyone shed some light on this for me or help point me in the right direction?

Thanks

AFAIK the 74p and 82p are production run numbers and the ones you order may have different numbers altogether. Also, make sure you check its complement (should be a 2sa1215.
