For indoor use, definitely go with the sealed gel-cells. A MUCH SAFER way to go. Happy Tunes!
Why not power your own DC
With all the products out there that run on wall warts, ie 3,6,9,12,18 volts DC (lots of DA, phono amps and even some pre-amps) why don't more people run their own DC instead of using the warts or buying the manufacture's outboard battery system?
I am amazed that the manufactures outboard units can cost anywhere from $200-1000, when one can be built using lead cell batteries for $50 or so. Using the lead batteries would allow for recharging and one could also choose the amout of amps they need or would like.
