While working on the B3 of a french musician, I took some pictures and put them later together with some explaining text.
So I created a documentation of getting rid of the attached wall wart and installing a DC jack which permits using and detaching alternative power supplies or batteries.
I don't know how long I will be able to host this file (http://www.tfrenkel.com/theremin/b3_europe_mod.pdf), so if it is of common interest it may be copied and hosted here on Theremin World.
