I might be wrong, but I don't think his calculations can be used in the circuit I have in mind. Here's an example from the magazine. I kind of like the local feedback around each valve, and passive eq between them, rather than some global feedback schema that includes the eq network.

The filter is lumped together as a single stage and is inluenced by the values of the valve stages in the circuit as well.

Here's the addon RIAA eq.

Anyway, they have already calculated and tested the values required, unless someone mentions another one I might need (and can't produce using these plus the bass/treble cut/boost filters). I see from his tables of data that the microgroove eqs are well covered, and I don't think I want/need multiple 78 filters. I will make do with the one and tweak it.
