[sdiy] Slightly OT: Tango RIAA network schematic anywhere ?

[Michael Buchstaller]

Hello friends,

i need to build a turntable preamp for a friend. Of course this
requires an RIAA tone correction network.
He vaguely remembers that there has been a passive unit
made by Tango that contained a "box" with inductors that was
capable on doing this job.

Does anyone know a link to this one ? Or another inductor-based
RIAA stage ?

TIA !
