Q: Why the transistor surface dust? A: This is the anti-static powder, rather than dust. Q: Sanken has been discontinued 2SA1215 and 2SC2921? A: Some friends say Sanken has been discontinued 2SA1215 and 2SC2921, about the information I asked Sanken agents, until today(31st-January-2013) has not been discontinued 2SA1215 and 2SC2921, about these you can contact SanKen or arents, or visit SanKen website. 8311A     Your partner for managing your online business
