Hiow to replace wall wart on step up with battery


I've been thinking of trying to replace the wall wart on the Benz Lukaschek step up with some form of battery power supply. Has anyone done this or have any ideas about how it might be done?
Thanks for any input.

If it is a DC power supply, it would be easy. Just read how many volts the existing one supplies and the wattage and get enough batteries to equal it and wire them in series or parralel.
Rouvin: I have the same phono unit: version T-8.
I would like to hear any suggestions you come up with as well.
I have always wondered, looking at the plug-in wire and wall wart, if an "upgrade" or "mod" to this part of the design could be an improvement. Also, does anyone know if there is much difference, if at all, between versions T-8 and T-9?
Thanks...

RWwear,
Thanks. This sounds almost too easy to be true, but I'll start looking into this

I haven't heard them side by side in the same system, but there is a bit of opinion on the two on Ausio Asylum:

...always something newer or better....
