I'm currently working on a pair of these beauties. For those who are not familiar with the M367, it's an ORTF (French broadcast organisation) version of the U67. Main difference is that it uses an AC701 in lieu of the EF86.
Both mics work and sound well but level seems a bit shy. Measuring capsule polarization voltage reads 54V instead of the expected 60.
Thing is 120V reads 120V. Both R12 & R13 measure 2M2. C4 is good and shows several MΩ of ESR....
But I still get only 54V! What is it I am missing?
