call me crazy but why don't you just buy a Sound professionals battery box with bass rolloff and the adjustable levels to turn it down, and have your DPA's reqired with a miniplug? Save you a shitload of trouble.

thanks for the suggestion!
unfortunately i don't think the SP box would make a difference, because AFAIK it does not provide any gain.
i'm trying to use the transformers because they provide the gain i need, and they are small and clean sounding
if i can cram them inside my current, small batt box that would be superb !!!!
it's like having an invisible high end preamp!!!!
ok i've been inspecting the stuff and heres a quick and dirt schematic (for 1 channel)

--------------------------------&--&---------now i have some questions
is the capacitor strictly needed now i have a transformer?
in case it is required, may i move it to the other side of the transformer?
(so as to be able to make it smaller)
i hope these questions make sense...i don't remember much about electronics
(although i'm somewhat good at drawing ASCII transformers)
btw, thanks marc for the hosas!!!!
one channel works fine and provides loadsa gain !!!
the other seems to have a lousy contact, but i think they will work fine after they have been rewired
still have not used them in the field but i'm eager to do so when all works fine (and everything is small enough!)
