Transistor Identification

[Jonas]

well... I decided to open an old computer power source and do some recycling. The problem is that I found some wierd marked components. Can you help me, is there some online place that I can go looking?

cheers!

uuhhh... some the strangest things!

945p
c9013
1815
a733

and some power transistors

Okay... I'm guess ing the 945 is an A945
the 1815 is a C1815
C9013 is as stated and the A733 is as stated...
These are all OEM trannies. These are for the most part all small signal trannies but the pinouts are prolly different from the norm. You could use them for some applications altho the gains may be on the low side. I have used C1845's in pedals but they sound awful dark and the pinouts are weird (ECB I believe) I have used the A733 with some success but again dark and pinout. I've yet to get anything remotely useful out of the 945, but I have seen 1815's in some cheaper pedals.
