I suspect that you can pick out the transformer-coupled ECM 8000s with an
ohm meter - then would be the ones with electrical continuity on the order
of a few 100's ohms or less between pins 2 & 3. The electronically-balanced
outputs also have continuity, but its more like 195K. I checked my inventory
and both the good and bad ECM 8000s measure about 195K ohm pin2-pin3. IOW
they are both he electronically-balanced (recent) models.


And if you had transformer-coupled mics, they'd most likely be ruined.
Tiny transformers can get permanently magnetized by even the small DC
currents of an ohm meter.

NEVER measure microphone- or MC transformers with an ohm meter.
