[time-nuts] Low noise power supply recommendations

[Will Matney]

Hello,

I am in need of a very clean 24 Vdc power source, to replace some old
mercury cell batteries with. What would a good low noise, clean, power
supply be in your recommendations? I thought of using two 12 Vdc lead-acid
batteries in series, and making a charging circuit with regulators, but I
am hoping to purchase a good used supply off ebay, etc. The old circuit
used two 12 Vdc snap terminal mercury batteries in series, for 24 Vdc,
along with a 7 Vdc mercury cell, and two plain AA carbon 1.5 Vdc batteries
in series for 3 volts. Any help and or ideas would be appreciated.

Thanks

Will
