I need to track some of these down and i'm having trouble locating locating who makes them and what kind they are. of course they're germs, just having trouble pinpointing the specs. heres a pic of them, you can see their prints on each, and it looks like theres an X preceding the numbers on each one but are heavily rubbed off...
transistor 1: X(?)2539052-546
transistor 2: X(?) 2539052-606
