Carbon microphones used a transformer for isolation; the primary circuit had the carbon cell in series with the battery. The carbon cell changed resistance (slightly!) in response to sound pressure, and the transformer amplified these changes. The output should therefore be isolated from everything else - whether you can get a useful signal can only be found by experiment. | |

Judging from the second link, the 4V input is power. The V one is probably the output. Do you have an access to a scope?
