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.

For indoor use, definitely go with the sealed gel-cells. A MUCH SAFER way to go. Happy Tunes!

Stan Warren and Chuck Jones are working on an DIY power supply for the MSB Link DAC, which will hopefully be better and cheaper than the MSB P1000.

```Recharging a lead/acid battery gives off hydrogen gas, Very explosive and corrosive to the lungs. Hence the ventilation reason. If you ever experienced a hydrogen gas explosion I'm sure you would never want another one close up or in a home(with a battery; acid everywhere ). Just be carefull, use common sense. Any spark will set it off.
