  • Totally! Is this no longer common knowledge? Maybe it’s a codger vs. youngster thing (already? I’m only 45!) but when I was a kid, the reason we liked playing with old phones (real Western Electric ones) was that they all used carbon mikes, so all you have to do is hook the earphone, mike, and a battery or two (dry cells last forever and have nice binding posts on top) and you can hear what’s being said. No active components at all. But that means the mike on its own has NO output.

No public wish lists :(
