I was hoping to find a pre-assembled charger & battery, but may have

Don't count on anything from Harbor Freight being RF-quiet. :)
Here's a simple hysteresis-type charge controller that is RF-quiet. It's
also cheap -- $20. It's not as efficient as the Genesun, but may be
enough to run a preamp, depending on the panel(s) and battery. Remember
that unless the preamp is switched on and off when not in use, that 130
mA becomes 3.1 Ah if runing 24/7. And if your use is mostly during the
winter, take into account that days are shorter and sometimes not very
bright.
