Title: Help with building external power source
Post by: Patrick on December 18, 2006, 10:43:31 PM

I have a custom made preamp that runs from 4 - 9volt batteries.  I'd like to try and build a power system that will allow me to power the unit for more than the current estimated time of "2 shows."

I have a ton of wally-world batteries and am good with a solering iron and stuff like that.  I just really don't know where to start on this thing.  I know there is alot of information I am leaving out, please let me know what I need to tell you.  Pictures can be taken too :)

Any help?

pat what up - i would think that just one of those wallyworld batteries would have much more run time than 4 small 9V batteries. i could be wrong though. if I were you i would just run it off one of those things. if you want more juice then wire a couple of them in parallel and you should be good for a longgg time

is that helpful?

I think you should contact whoever made your custom box for advice.  At a minimum, you need to find out how the 9vs are wired, and what components they power.  Are all 4 wired in parallel?  In series?  Are the first two wired in parallel with one another and the other two in series?  Or vice versa?  Etc.

Gotcha.  Thanks Brian, will do.  To me it looks like the 9v's are wired in parallell but alot of the wiring is buried in a thick layer of epoxy.
