Interesting. I can get the BC179, it has a good noise figure but is low voltage (only 20v apparently), I need one 40v+. This is what rules out the BC559 too, which I have a few of. The BC560 appears to be a higher voltage model of it though? I can get it here for quite a high price and depending if its in stock locally (don't want to pay for delivery whereas I'd get it free at Rapid by buying along with other parts):

It just says BC560, I think BC560C is best for low noise? Either way, the BC560 seems to show under 4db, typ 1db which should be fine. Anyone know how that PN2907 compares on noise? Or the BC636?
