I have been searching about this for a while, but seems quite dificult to find solutions.
The best way to go supply a preamp from a battery without waste energy is using a smps. But seems not easy to get one clean enough for good preamps. Although I´m pretty sure that can be done. So I´ll pray God for a reply of any genius here to switch a light.. :roll:
