How funny, I'm actually building the same preamp with the same LM chip,
I've only tested it on an oscilloscoop and it seems to work,
just waiting for my LM chip that i've ordered, then I can fit it in my case,
I cant wait until I hear the sound coming out of it,
Has anyone build it by now?
I'm also curious what I have to do, to supply it with a +/- 20V ?
