Workman T-747 CB Microphone Tester

T747 Mic and Echo Board Tester. Tests a large variety of microphones including most from RCI, Magnum, Cobra, President and Midland. There are spring loaded terminals on both sides of the tester so that you can easily connect and test noise toys and echo boards.

The test center runs on 12VDC and has a standard 3-pin power cord jack as found on most CB radios.

Note: If you want to use this tester on a 12 Volt source, you will need to buy the CB3A Power Cord. See the link at the bottom of this page.
