CTX3030 & Gray Ghost NDT (Sun Ray Pro Gold Headphones).
These headphones are in direct connection is not disconnected the internal speaker. Need wiring diagram of these headphones, to convert a T3030.

This was discussed thourouly in earlier topics. You may want to go back to some of the earlier pages about this problem. Also you can get an adaptor from Radio Shack for less than $3.00 I think from mono to stereo is the one used. HH

Thank you for reading this post. With the adapter is a shaky structure. Want to resolder the headphone jack. The cord is wired as needed.

I wasn't pleased with the adapter plug making the connection "longer" either. That is why I made the short, flexible, pigtail. What I found with my GG Originals and GG NDTs' is that the 90 degree plug had to be inserted with a certain rotation to make complete contact. The pigtail removes that requirement. With that said, if you are wanting to adapt your GG NDT's to plug directly into the CTX 3030, all you have to do is strap the sleeve lead to the ring lead. My advice would be to get an Ohm meter and find continuity between the wiring inside the earcup and the plug. Once you determine which wires represent the ring lead and sleeve, simply solder a strap between them at their initial point of contact inside the earcup. I was able to do it with my GG Originals. But after building the pigtail adapter, I changed them back to their original state. JMHO HH Randy

Well. Will use different versions.

Disassembled the headphones, if not mistaken that's wiring diagram.
Enough to put a jumper between the center and right Shtyrkov Connectors.

Or soldered as in the photo. The switch will not work, it can be deleted.

Is that the original schematic or the one for the modification?

 

[Digger]

The schematics are from Minelab's website.

The first figure and schematic is the original. Photo last for CTX.
