A phono stage input capacitance of 200 pf would make it impossible to optimally match nearly all of those cartridges, the possible exceptions being those in the 250 to 300 pf area when used with short lengths of low capacitance cables.
The input capacitance of the JC-3 is about 200 pF.
How did you obtain that information?
