[ARC5] Carbon mic replacements

[Dennis DuValll]

Here is a simple circuit I have been using for years as a replacement for T-17 elements.  Have found that the speech  quality is significantly affected by the physical mounting and location of the element inside
the T-17 case.

Have been using Radio Shack elements but don’t know if that source is still viable or not.
