I bought these transistors a while ago from Digikey to use in a couple of amps I was planning to build. However, since then, I've become more interested in headphones, and I need the money for a headphone amp that I'm building. I have 10 of each and I'd like to sell them as a group. I spent about $120 on these, I'd like to sell them for $50 shipped in the CONUS. I'll ship to other countries, just send me an email so we can work out shipping costs.
