Hello Claus, thanks for your explanation! From my testings I found that you can get a similar error by leaving RL2A out and reducing C2 slightly and adjusting the other values around it. But, and this seems to be the important point, which was not clear to before: you loose the contstant impedance ...

4th time constant for LCR RIAA

Hello docali, I confirm that RL2 is the sum of RL2A.1||RL2A.2 and RL2.Cu. and RL1 is the sum of RL1A.1||RL1A.2 and RL1.Cu. Under consideration of fixed time constants and fixed impedance (e.g., 600Ohm) there is a clear dependency between the inductances and their series resistances; means if you cha...

Passive RIAA filter design including tool

Sorry for answering so late. I published my white paper in another forum. In the attachment you can find a copy. I hope to get some response for discussion.

I'm working on a white paper regarding mathematics background and an Excel tool for exact calculation of each component with free choice of the impedance (e.g., 600 Ohm), but this will take a couple of weeks more. Please find attached a LTSpice simulation with imported values from my Excel tool. The...
