Mark Levinson No 52 Preamp phono stage custom loading

The ML site has a download for HIFI news article, for the phono stage, it states:

"Custom input loads, should one be required, can be configured using internal solder-less connections by your dealer."

The ML user manual is not much help either:

"R Load: This setting offers a choice of resistive loading values for the Phono input:
• 47k ohms: The most commonly specified value for most phono cartridges.
• 3.3, 5.0, 7.7, 10, 33, 50, 77, 100, and 330 ohms
• Other: Enables the use of a custom-installed load. If you require a custom load to match your phono setup, contact your authorized Mark Levinson dealer for details"

Does anyone know about how the custom loading is done or has anyone done this? Sounds like jumpers or something, but I cannot find any info on how to accomplish this, thanks.

If you're talking about plugs that have a female input to a male output with a 900 ohm resistor from hot to ground, then that will work.  

But before you do anything, try listening to your cartridge with no additional loading.  I've been using MC carts, including some expensive ones, for years without any added loading.  You might be satisfied with the sound without any loading.
