Teemuk, since this $%^&* won't even acknowledge your work, I'll say "Thank you". I found it very helpful.

See posts 2,4,5 and 11 for your answer - they all say the same thing: use the BC546/BC556 as shown. Any grade would be fine They are just a few cents at Mouser, why torment yourself over it?I also have a bunch of BC546C and BC556C, of which I would be happy to sell you up to 4,000 of each. Since you'll probably find many of your other parts at Mouser (once you figure out appropriate values) that likely makes more sense.

4000?

Were you planning to make an output stage with them...

No,
Bob thought that by buying up the world stock of C grade he could prevent all the rest of us from building any decent front ends for our amps.

His ploy failed when he offered them as part of a group buy for the benefit of our community.

It did stop all the others from improving their front ends!

Nah. That's just what happens when you commit to a group buy design and the distributor runs out. For a couple of months the minimum buy quantity was 10,000 of each. I've managed to unload a few of the 9,500 extras, even used a few myself.
