My stock Koss 30's broke yesterday at the jack. I bought a new 1/4 inch jack today at radio shack. I am having a devil of a time wiring it correctly. Wired and re-soldered 3 times already. Results were one ear live, the other ear live, and nothing. Red, White, Black. Which wire goes to the ground (casing)?

Thanks!

Oh yes I am sorry about that.
It's happened to me before.
Can I suggest something?

Look up your local electronics guy in town he will do it for less than 10 bucks.
It's well worth the frustration you will endure.

Sorry you're having problems. My stock Koss also broke shortly after using the e-trac (Cheap Crap) so went to radio shack and they also installed a new heavy duty connector, cost complete $19.00 it was well worth the money. :icon_thumleft:

I am going to assume that you are actually replacing the plug on the headphones, the jack would be on the detector.

I would contact the maker and ask for the wiring/colors. They should give you them, by identifying the Tip, Ring, and Sleeve of the stereo plug. Tip is the end, ring middle and sleeve inner. By the way be sure to insulate the connections, with heat shrink if possible, and maybe clean with flux /pcboard cleaner.

Another thought. If you still have the pug and can strip it back to isolate each wire you can check with an Ohm meter to get the wiring. Just write down the colors for TSR see above post.

I hope this helps.
