When I wanted to put 4 batteries (14.8v) in, something went wrong. And now pb2 does not work on batteries :( I Think add more batteries, up to 6 (22.2v) and use as an external source :)

I found Taiwan seller. Thanks!

I listened to lme49990, I really like them! If only it hadn't been for that crack... With the blue Buffer, the crackling is not audible. But, I'd like to listen with a dummy buffer! Can who knows, how much cost original lme49990?

Can anyone know where I can buy the original LME49990? I think I have noname opamp...

Can anyone come across... At me, why that if to connect with dyummy buffer, LME49990 from a network crack. With normal buffer all works fine. I dont have battery to test with it.

OK. I try ADA4897-1 becase price is very nice! Thanks!

With Both chip i guess? Maybe I'll leave it as it is :) Love warm sound :3 And darkest too! Have you tried role db2 opamp? With blue it sounds wider and YAMY :3 Whats opamp in your db2? Thank you for the fast replay!
