Unfortunately for some years now it has been difficult, aggravating, and often fruitless to try to get response or service out of Audible Illusions or its owner/manager Art Ferris. If you should succeed in getting hem to accept your preamp for altering, it could be--literally!-- years before you get it back.I think you would be better off getting a decent "head amp." That's what they used to call an active moving coil stepup device. There are also passive mc transformers out there.
For what it's worth, I believe the Mod 3A's phono stage to be well worth using, even with an outboard mc stepup device.
