                               \
 ---ground----------------------)---+--------------------shield-----
                               /    |
 ---hot--------+----10k ohm-- "+"  "-"

Nice work.

If I were you, I'd isolate the soldered joins in order to avoid short circuit. (hope you understand my crappy tech english  :o ).

A bit better schematics ;)

I built this + it successfully powered my DPA 4061's.  The SP-Preamp does the job now though.
