| I would HIGHLY recommend putting a fuse between Switch and D1. |

| It is a good sample design. Be careful you could be in dangers getting electric shock by using this design do to component failed. I would not follow this design as is. |

| Where can I find a 10K to 600 Ohm transformer? I cannot find anything that is too ridiculously expensive. |

| I just built this circuit, and it doesn't work, any troubleshooting tips? which way does the transformer go? I've checked the circuit to the schematic and it seems right to me, except I'm not sure about the transformer. |

| Just built this circuit and it works great. Using a RCA connector instead of the mic and connecting it to the audio of my home theater system. |

| 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) |

| Is there a way where instead of there being a mic for your sound input that you could wire either rca cords or like 3-4 3.5 jack inputs for your sound and if so what are the schematics of it....thanks for your time and please email me back |

| Changes for 230 V AC Version:
C1 & C2 = 22µf 500V Electrolytic Capacitor
R1 = 100k 1/2 W Resistor
Q3, Q4 & Q5 = C106D or S4003L
Changes for 12 V DC Version:
remove C1, C2 & R2
replace D1 & R1 with a wire
connect +12V on top (common at bottom)
use 12V bulbs ;)

| The circuit schematic, pictorial, board layout etc shown here are identical to kit #152 offered by Graymark Int'l Inc, POB 2015, Tustin Ca 92781. Beware identification of the primary and secondary of T1 is vague and ambiguous. Obviously, it will not work with T1 installed backwards. For other kits, check Hobbytron.com (where I got the Graymark kit on closeout). |

| Is there another type of transformer I could use with the 120v circuit? It's a bit hard to find that transformer and when I did it was an $80 piece. Can a power transformer do the same thing or maybe a less expensive transformer. HELP QUICK PLEASE
Thank You,

| To help out, an audio transformer is just that an audio transformer. Try finding one on mouser.com or hell radio shack should have them. I dont think I would be building this with out a fuse or at least using a GFI to plug it into ***note GFI may not stay set with the fast changeing current draw this will have.*** None the less use saftey |
