The long answer is that SiGe (silicon-germanium combinations) are one of = the very latest things for transistors for extremely high frequencies=20 (up in the microwave range). But they're not what you're looking for. Electronic Goldmine has some NOS (very old) germanium transistors for $1 = each: http://sales.goldmine-elec.com/prodinfo.asp?prodid=3D3661 -- http://www.piclist.com hint: The PICList is archived three different ways.
