These are new production transistors, and there is not a limited stock of these at this time.

I bought a few of these about a month ago and have had plenty of time to try these out in a 60s style solid state amp that I had built. In comparison to a 2N2222 silicon npn these have a little less gain and a bit more noise but not by much (think 12au7 vs. 12ax7). Only one warning though, the collector- emitter breakdown voltage is quite low (see specs) as opposed to +- 60v for 2n2222 or 2n3904 so be mindful of the operating voltage of the circuit. On a final note, I have not been able to test these in a transistor radio because most of them use pnp transistors exclusively! But regardless, they are perfect for getting that retro solid state look!
