Default Hiraga preamp line+phono 4xECC81 SRPP

Hi All!

I need your experience.
I need the electric schematics of this pre, but my friend say that there are a lot.
This has phono MM, CLC power supply regulated, with 220mF MKP 630V and is essential.
Carbon pot, 5 ways selector.

If you are so kind to see your French magazines of 30 years ago of The Audiophile, I'll be very happy.

Thanks, but it's similar but not identical.
Mine has only 4 ECC81 (2 for line, and 2 for phono MM).
No others tubes.
Maybe it's a simplified version?

Thanks for repling,
