Hi! I have this RIAA, (from far-east), that is fairly unusable...sounds like it is far off the curve....and no good overall sound...
Please give me some suggestions on how to upgrade, and calculate the riaa-filter...
Maybe go for other tube-types too?

I think with two stages and negative feedback you have too small sensitivity of RIAA corrector to reach standard output level 1Vrms. Try circuit with 3 stages and without negative feedback, like this: http://audio.ring.lt/pre/pre_en.html
