[TenTec] Weak Output from 706 Microphone and your recommendations.

[Phil Sussman]

>From a technical point of view, I think a determination needs to be
made as to whether this is a microphone problem or a rig problem
This could be anything from a defective mic to a dirty pot in the
rig.

The easiest way to make this determination is by like/kind substitution.
Connect the suspect mic to another rig -- or connect a known good mic to
the rig in question.

Otherwise, you're spending money to fix/replace a mic that may not 
even be defective.

Just a thought!
