Instead of Faraday shielding, might I suggest an axe for multiple other 
reasons also? ;)

Is your preamp specifically for MC and not MM?
The MC preamps are designed for higher amplification as well as having 
different load/capacitance on the input. I'm daft to presume you don't 
know this, after all, you've bought the gear :)
Ground loop? Bad, or non-existent grounding in the TT?
Simple fact is, a lot of the 'good' gear was designed for a world before 
these high powered, high frequency air waves, so replacing the 
interconnects from the TT with good shielded cables and adding some 
simple shielding inside the TT and preamp may be the only option that 
will make any difference.

These might help, might not:

Mobile phones are shat for this. With a lot of audio gear, you can tell 
when one is going to ring seconds before it does and no minor tweaking 
will completely remove this "precognitive superpower".

Oh, and HBD :)
