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
