Do whatever it takes to duplicate the wiring of good earpiece to the one that is not working and that should resolve the issue.

Search for CB TRICKS on the internet. All the information you could ever need for this type of information is at that website.

attach the wires according to the schematic you got with the radio telling you what wires do what. Those wire go on pins 1 - 4 The yellow wire is not connected.

White wire goes to J13, Red wire goes to J12. Hope this helps ;)

Old question, but may be somebody else is experiencing the same issue. The earcup without the boom has a noise cancelling board, so it could be one of the wires that goes from one board to the other one. Gently take the earcup off and look at the 4 wires that are soldered on top (red, black, shield and white). If one of these is cut, the speaker/anr won't work. You will need a very small soldering iron to repair it (no more than 15 - 20 watts). Good luck, hope this helps ;)

Don't know why answers for different type of headsets shown up on a question about the Telex 850. Probably there is an issue with the cord. The cord has two shielded "double" wires on each pair. The ones for the mic are "white" and "light blue". May be one is cut preventing the mic to work. Look around for a local avionics shop, they should be able to fix it. Hope this helps ;)

when you peak those radios you are causing them to be very WIDE & thats whynot to mention its illegal to do

You need a wiring diagram for the radio and mic. or take it to a CB shop.

An equalizer circuit or filter? No idea where this would as you only give the result not total environment.
