| C2 should be 50V not 250V, also this circuit works just as well if the mic leads are replaced with left and right in-line stereo |

| I have built this and it works great. For those asking, connecting the two leads from a headphone jack cord or whatever to where the mic leads would be works just as well. |

| I've just built this schematic here in my classroom and am having difficulties with it. I noticed when I ordered the crystal microphone from Mouser Electronics that it is polarized but it is not specified in the schematic. I've tried both ways: one way I get a buzz sound and it was stop as I touched the mic, the other I got nothing lol. I'm not quite sure what I'm doing wrong here. I also did a ohm reading on the transformer I ordered as well. I ordered the same one on your parts list however I'm getting a reading of only a few ohms I'm guessing that could be the issue lol. Any ideas would be great. |

| Can a 10K:10 ohm-audio transformer be used? If not, what can I do to increase 10 ohms to 600 ohms without changing any other values? |

| Is there any way to make them more responsive. I made a 120v one and compared to my friends, who made the same thing, It takes a larger audio input signal. For an input, I used compression terminals that connect to the audio transformer (Mouser 42TM114-RC) |
