Join David as he repairs the microphone plug on a David Clark H10-13.4 headset. Music (Pinnacle 19.5 royalty-free music): Pulsing Dance Reaction Time City Night Groove
thanks for sharing actually im Avionics License Engineer and never fix my own headset before so your tutorial is so helpfully but you didn't show us the wiring diagram sir, it's important i think to prevent wrong soldering
Hi I bought a David Clark H10-13.4 recently and after about just one month, the microphone stopped working and then I tried changing the mouth piece (microphone M-7A) with a new one thinking it was the issue but still didn’t work. What could be the issue. Please help
I put a cheap digital voltmeter across the plug sleeve and the middle contact (not the tip). I turned it to the lowest DC volts range and rapidly tapped the mic with my finger. The reading went from about 0 volts to about 1 volt, and returned to about 0 volts after I stopped tapping. If you don't see a voltage, I would suspect a bad wire. I haven't tried it, bur you could try the mouthpiece alone and see if that works; then you know for sure it is a bad wire or connector. If you are in the headphone, you could check continuity between the mic and the connector. Good luck!
hi, i'm confused why the tip isn't used? Looking at schematics of the aircraft radio socket, i thought the Tip was for PTT function? are you able to explain a bit further? cheers
Hi, thanks for watching! Yes, you're absolutely right, the tip is used for PTT. However, these headphones don't have a PTT button on them. The headphones have audio only; the PTT button is separate. These plug into a separate button which adds the PTT function before plugging into the socket on the plane. Hope that helps.
Hi, I recently took apart my DCs to put in an ANR kit, and I noticed a 3rd clear wire that connects from the power cable to the microphone and crossover cable, but doesn't actually enter the other ear cup. Would you happen to know what it does or what it's for?
I'n not familiar with the ANR kit; but I took a look at the installation manual. I'm not sure, but I think it is a shield wire. Check with a VOM; but perhaps it should be connected to the other "chassis grounds". Good luck!
@@LifewithDavid1 Thanks for responding! I'm pretty sure it's just a drain wire for the shield cables. When I cut the old power and crossover cable to check what it was the conductors were just spiralling around the the cable. I looked it up and a cylinder shapes around wires indicate shielded wiring, so it seems like I should just solder it to ground.
thank you for this video, my PJ-68B plug is also broken on my DC 10-13.4 and I will replace it like you with a Neutrik NP3 CM-B, but I would also like to take the opportunity to change the PJ-055 with a Neutrik NP2 X-B is the right model in your opinion ? Thank you for your reply
I THINK the Neutrik NP2 X-B will work, but I don't see it specifically meets M642/4-1. However, I see that Switchcraft 440X does meet MIL Spec. M642/4-1. Good luck!
It looks like the Neutrik NP2CM-B plug (from Mouser) meets Mil Spec 624/4. This plug appears to be the companion to the microphone plug; except it has tin vs. gold plating. Good luck!
hello, can you show a drawing on the diagram of the soldering wires for the Neutrik NP3 CM-B but also for the NP2X-B because unfortunately I cannot translate your words...😏thank you very much
That would be interesting. However, I like to verify that what I present actually works before I publish it. Since I don't fly helicopters, I don't have an opportunity to test whether the fix actually works. I understand that impedance matching would be required; perhaps a better solution would be to purchase fixed wing to helicopter adapter that already has the impedance matching circuitry included: www.mypilotstore.com/MyPilotStore/sep/1192?gclid=CjwKCAjwhuCKBhADEiwA1HegOb7R70ra8hVrQ-ijketUkIKa8WV33jLNb9oHUtL_4fFLGaj3Kx8aWxoCTL4QAvD_BwE
Sometimes in the military surplus end of the market I have found pj socket to helo type adaptor leads, and helo socket to pj plugs so that might help with bench tests 👍🏻
As you might have seen from my other videos, I enjoy electronics and have a substantial number of test instruments. For this; I just checked continuity. The proof is in the pudding, so the final test was an operational check in my plane. Thanks for watching!
