Thanks again for the valuable advice
I read something about op-amps
The first thing that hits me is the huge open loop gain
But i feel than in a phono preamp this could be useful
I would like to listen a phono preamp powered by batteries ... i am curious about Sutherland Engineering preamps for instance
For the output stage actually the use of opamps looks a little strange
Very good output stages can be made out of discretes i guess
Lately i have discovered LTSpice and i am playing with it
It is impressive, at least on the paper, how even very textbook circuits can give very good performance selecting the right working conditions
I have ordered some breadboards ... i am curious
Thanks again
Kind regards,
bg
