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.

Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

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?

>>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.
