Jean Hiraga RIAA Phono

[pieter t]

"Le tube" was single ECC83/12AX7a, both halves gain stages with passive as well as feedback RIAA correction.

See:

Pramplificateur "Minimum" "Le tube" (J.Hiraga)

At the end of the article you read that Maison de l'Audiophile neither offered a kit nor components; apparently there was commercial interest.

I had recently found this, and wonder if it might be the beast in question:

Some interesting design variants in this thread. Thanks all.

Thanks, I have seen this but I have already started a point to point wiring; I won't use the RIAA. I'll report back later!

You could do it with a 1 amp slow blow, if this is really what you want to build.

Ok. Thanks for your help. Is a 20 years old design, but buget wise i think is my only option now. And I think it would outperform the musical fidelity xlp.

Thanks,
