I meant BC847BPN, they're stocked at ELFA.

Lumba, for the sake of miniaturization, something really pocketable.

Typo error.

This should have read 0.05-0.1um.

If you'll check my blog, you can get pcb's for free but only a limited number so hurry up.

Looks good but I am hoping there is a non surface mount version :P. I already have lots of transistors I want to use too.

I was thinking of using a volume control with a buffer like this super buffer as a headphone amp/preamp. But how to solve the problem of DC offset? Would it be possible to keep it all DC coupled, no capacitors in the audio path?
