Sorry, I misstated the idea. After re-reading the info for my Chinook pre, their example takes a cart spec'ed at 150pf and subtracts the cable rating, say, 90pf resulting in 60pf. So the start point in the example would be either 47pf or 100pf in the case of the JD-9. Using 300pf and 90pf would result in 210pf at the high end. So, just about all of the settings of the JD-9 cover your cartridge. This shows that you should try most of the settings and pick the one that you like best.
