Hello.

This is my first post in the forum.

I would like to show the pre-phono RIAA that I mounted based on the posted scheme, I used the same values for the components that the schematic diagram informs, the sound result I found very good. My Toca disks uses a Shure capsule, with needle N75.

If anyone had suggestions for improvements in any part of the circuit, I thank you very much.
