Transistor search

Hey!  Anybody have, or know where I can get, some BC172b trannies? Digikey and Small Bear don't have them, haven't checked anywhere else yet.  Thanks!

There's some on Ebay but quite expensive.

Bob--

By the datasheet, there is nothing special about that number; NPN silicon, gain of 180-ish, CBE pinout. If you have a 2N3904, 2N2222 or BC108 among your spares, one of those should work.

Thanks to you both!
