anybody got the datasheet for these pentodes? just really need to know the pinout and what kind of voltage it likes at the anode.  was goint to use them for a pair of tube mics.

plus has anybody used T bone microphones? thinking that they have nice cases, and can use there capsuel to test everything works before buying expensive capsuels from blue, neumann etc

Gawd... except for the octal base, that looks just like a fuse from my old apartment building.
