I don't know what the current drain is on your R75, but a few people have mentioned running Drake R8's on car batteries. They charge them with trickle chargers.

My "portable" 7030+ system has two pairs of NIMH battery packs designed for RC cars. They give me about 9 hours of listening on a charge. But the 7030 draws very little power for a tabletop.

One advantage of a battery system is you'll be ready to listen during power failures - when the noise level is extra low because nobody in the neighborhood is using gizmos that generate RFI.
