That's exactly what I did but I managed to do it in the shop and only buying the ones I selected (used to buy a lot there ;-) The big problem is that you need two matched pairs for stereo and you will find yourself sitting with a single very good matched pair and multiple less-matched pairs that are however at the same hfe. I always got that single pair too, saving it for the day I found a second one just like it but I just ended up with dozens of these pairs that I could only use for mono-designs (which I almost never did, so they were never used). Also, a pair consists of one NPN and one PNP transistor so you can never match with a heap of transistors from the same manufacturing batch. I always needed single-malt therapy afterwards. I need it now from just thinking about it again ;-) cheers, Nick. -- DeVerm ------------------------------------------------------------------------ DeVerm's Profile: http://forums.slimdevices.com/member.php?userid=18104 View this thread: http://forums.slimdevices.com/showthread.php?t=56068 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
