Add on electret mic tester.

[Trapper267]

Here's a little add on electret mic tester to work with my mic tester to check electret mic's. it's more compact than the huge mic tester i built and only made to test electret mic's.

The triple pole, double pole switch on the back kill's the electret part of the circuit out so you can check a standard mic, then turn on the electret part to verify it's operation. 73
