Earlier this year I built a dual mono phono stage for myself, where the two gain stages are inductively plate choke loaded and RIAA EQ is performed split-passive. RIAA curve tracking is very accurate: I calculated the initial component values and fine-tuned using my AP. You need very good plate chokes and shielding around them. As Paul said above, you need to use high inductance chokes and/or low-medium impedance tubes.
