Thanks Walt for clarifying that the voltage probably sags when the
mic is in use.  This probably explain the difference between Rob D.
not having problems and me having them.

Maybe it's that the low-riders with phat steros in the neighborhood
are sucking up all my voltage with their phat bass vibrrations.
Human Nature recording?

Rob - yes thanks, I used your wiring diagrams.  Actually left the
TA-4 connectors on, and wired them in-line to a TA-4m to mini adaptor
I built.
