Hi my friends,
in the next future, i will finally get a new phono preamp and, while going to get it, I am trying to figure out how to properly supply it to get the best out of it.
The two main options are some kind of high quality / low noise power supply adapter or some kind of rechargeable battery, with the latter as the preferred method.
The phono preamp has a power consumption of 50mA , then quite low, and it needs 24V DC supply.
I am googleing around a bit in order to find the most obvious/suitable ideas to feed it with some rechargeable battery (and suitable charger), while possibly getting ease/convenience of use, being able to use the preamp for a good number of hours in a row or to leave it unused for some time, possibly keeping the battery charged so that I won't need to wait/recharge it just when i need to use the turntable, getting stable voltage while i am using it, the possibility to replace the batteries in a few years without needing to restart from scratch with a new device and, also, not breaking the bank... I understand these are quite a few constraints, though.
I see there are more options around, like Ni-MH battery cells, Li-ion cells, Lead batteries... many of which are quite high capacity (and, of course, more expensive) options suitable for devices which need a lot more power than such phono preamp.
So, which would be your best choice both in regards of a suitable low noise power supply and rechargeable batteries (together with a suitable charger)?
I'd be also ready to DIY a good solution, of course.
Thanks in advance,
Vince.
