Makes a lot of sense, Brian, and your circuit explanation too. I
believe Curt Olson tried a similar battery powered supply for his
WL183's with complications,

Maybe someone has succeeded and not yet reported it yet. :-)
Recordists gain requirements vary, but ECM capsules' signals remain
mic level with a battery boxes, right? Rob D.
