Cartridge advice

Move the 47K load resistors from the input jack tip to ground over to terminals 17/16 and 2/1.  (You'll need to solder a short piece of wire between the input ground connection of each input jack to the ground buss.)  You want the resistors on the SUT's secondaries rather than on the primaries (which are soldered to the input jack).

I didn’t realize the resistors needed to be moved. Is this necessary? If not, what is the advantage? Thanks.

Yes, you want the 47K resistors on the output side of the SUT.  Technically you could evaluate using no loading resistors at all if you wanted, but leaving them across the RCA jacks is approximately equivalent to no loading resistors at all.
