Here is one possible power solution...Home Depot and Lowes have self 
contained solar powered yard lights that switch on at dusk. Remove the 
lamp and use them for power sources at each pre-amp location. I don't 
know what the preamps have for current draw but I probably isn't much 
more than 100ma.  The the self contained rechargeable battery should 
handle that all night. If not add a inexpensive UPS supply 
replacements.  Such a power source would also mitigate any problems 
associated with ground loops, circuitry wire, power inserter etc.

Just a though and hope it works.
