Hey guys,

After a short restoration of very old DD Japanese TT, I decided to build simple MM RIAA preamp based on triodes. Preamp will be used only with Grado Gold cartridge (input load 47k, output 5mV at 1kHz).

Several months ago, I bought a PCB from 8audio.com, but I have some doubts. Can you please, have a look on that circuit and let me know, if that network is correct? I have no experience with RIAA networks and cannot judge. Maybe you got any other comments to that circuit. It looks for me very Dynaco like. I'll appreciate any comments.
