I was just looking at battery noise last week. I assume you need low noise, not good regulation. If so then in practical terms, I think the best thing you could do is get an 8 cell battery holder for AA cells then connect a 220 uF capacitor across it.
This is pretty good. has test results for several power supplies http://www.tnt-audio.com/clinica/regulators_noise1_e.html On Tue, Jun 14, 2011 at 4:02 PM, Will Matney <[email protected]> wrote: > Hello, > > I am in need of a very clean 24 Vdc power source, to replace some old > mercury cell batteries with.
