Well, the current problem is the fact everyone complains about my audio. 
    Tinny, yucky, narrow... like an old telephone, etc.

New (used) D104 is the worst of the bunch but known good mics that I 
have used for years, doing voice overs for film and video don't sound 
much better.

I taped tests of 3 of them and the D104 sounds lousy and the dynamic and 
electret lapel sound just fine and are nearly indistinguishable from 
each other.

When I put them under an earphone tuned to a good broadcast signal and 
fire the Ranger into a dummy or antenna, they all sound lousy.

Seems obvious the Ranger is doing something to the audio so I have been 
sig tracing to see where and the pics are what I found.

In the meantime, I removed caps one at a time from the front end and 
none of them made the slightest difference.  I left them all out and 
decided it's time for a break.

I have no idea where to go from here.
