Hello everyone!
I wish that I create (design) tube preamp or tube buffer with ECC82 (12AU7) for my CD player Tehnics and audio amplifier Tehnics to get the real-tube sound.;)
So please give recommend a good schematic (circuit) or project for tube preamp or tube buffer.
Thanks for your help!

The second one looks like it utilizes the low impedance characteristics of that tube better than the first one.
Personally, I prefer the 12AX7 for a tube sound preamp.

You really should experiment with a lower plate voltage to get a stronger tube sound. I have been very successful running a 12AX7 at 70 volts for guitars. Still, that is a specific application and it might suck badly for a full range hi-fi amplifier.
