PS Audio phono pre

[Plott]

Hi,
I would need some help please.
About 35 years ago I built a PS Audio phono pre, in which the RIAA-correction was made with a passive network between the input and output stages. That's all what I know of it after such a long time and now I'm searching for the circuit diagram.
Maybe someone could help, it would be much appreciated.
Many thanks in advance.

Hi Chris,
many thanks!
"Mine" had more transistors but based on this I've found the PS IV and I think this is it.
Many thanks again!
