Sub. for BC109, BC549
Can anyone suggest a Low Noise, similar gain, readly  
 
available sub. for both the BC109, and the BC549.  
 
Oh, and by the way (everybody probably knows this)  
 
Digikey now has the genuine Texas Instuments IC's.  
 
theres nothing like a "real" TL072, for big gain and low noise. Thanks Ed R.

The 2N5088, 2N5089 or 2N2484 will be very similar.

2N5088 are nearly impossible to get here in Germany, I allways substitute them with BC549B's wich are quite common over here ;-)

Here in Brazil too the BC series is the easiest to find.  
 
 
 
Won't a 2N3094 do the job?

I'm not familiar with that number but if you mean 2N3904, then the answer is yes, but the ones I suggested are speced as lower noise.
