"Haudegen": MM-Phono-EQ

Think, MT´s comment was referring to Post #116 and NOT #113

#117 refers to #114 which refers to #113...

Mark's posting #114 refers to the split riaa configuration shown as an example from my posting #113.

Now Mark adds R1 and R3 to 36.12kOhm and calculates the noise density to be 24[nV/sqrt(Hz)].
And that is quite simplified and ultimately not correct, which is what my posting #117 refers to. My posting #116 refers to the statement "and it has a gain at 1kHz of -20dB too" - and shows the solution to the 1/10 problem... Mark's posting #119 is nothing more than a red herring.

That's all

But now we don't want to play ping pong.

There are endless examples in the archives of how you can or could implement an RIAA EQ.
This equalizer was a very popular DIY project in Germany for quite a long time, just like the Thomas Scheu turntable drive.
