I've always assumed that must be true, but my faith was shaken
recently. A tech at Sennheiser taught me how to "align" the
electronics of an MKH mic, and when the one I was repairing was on the
money the sensitivity increased many dB! Now my question is (and I
should ask him), how often do MKH mics get out of alignment?

BTW the repair was necessitated by a blown capacitor, that probably
caused by a barrel phantom-to-T-power adaptor that presented a pulse
of 48V to the 12V T-power mic if it was hot-plugged. Most of the time
they seem to be able to survive this insult, but not always, as the
voltage rating of some internal caps is momentarily exceeded by a
factor of like 3X.
