This was my original posting, after a few days with no response I finally made it to my local Radio Shack and the guy behind the counter looks in his handy "cross reference manual" under 8050 and tells me the part is a 2N2222 transistor!! Can this be true?? I am having a hard time believing him (not that I don't trust his ability to read) so could someone please verify this for me? Thanks. -Steve -- ========================================== >>> Steve Heitke <> heitke@tellabs.COM <<< ==========================================

According to the Philips ECG data book, an 8050C is an NPN AF power amplifier transistor, silicon, 100 volts max, 0.5 watt max, TO-92 case, and might well require a heat sink. The specs I just gave you are actually for the ECG289A, which is their recommended replacement, rather than for the 8050C itself. They don't have a plain 8050 without the C.
