battery powered tube phonostage kit?

Hello, I was wondering if anyone knows of a battery powered tube phonostage, kit or assembled, what are the choices? I have a Well tempered classic w/Grado Statement Sonata(.5mv.) cart., and also a Lundahl step up trannie, so a mm stage is what i'm looking for.I like the Bottlehead Seduction, but building a batt. power supply for it is a little over my head. i guess my budget for a maxed out kit would be about $1200. +/- ? Any suggestions. Thanks, Alan
