Are we talking about Yugo or semiconductors? Come to think of it, even Yugos aren't that bad,

The feedback is probably at the correct point for the 2N4416A Vgs under bais for being equal to the BC550's base to emitter drop and output bias current times 220 ohms.
Are the 2N4416 and 2N5462 any good here ... ???
How about PN4416 (which is cheap) vs. 2N4416 ... ???
