Telephonics aviation headset

[Meatwad]

I picked up one of these saturday at a sale which also come with an helmet mounted mic. All of this runs through a single 1/4" jack which I assume ties into the radio panel. Without butchering the headset, what would I need to use to use both the transmit and receive audio for the headset?

If not readily possible, I do have a separate helmet mounted mic that also uses a separate 1/4" jack that is completely isolated from the headset jack

Forgot, model H-173A/A1C

To use it with a computer?  Does it have a TRShttp://www.americanmusical.com/ProductImages/Large/p347.jpg jack?  If so, it has a common ground and one ring for headset and one for mic.  Figure out which is which by experimenting and rig up an adapter.  All parts are available at your local electronics store.

^^^ What he said.

Nope, the 1/4" jack has a ground and then a center pin so it just has two connections, not three

Look at Aircraft Spruce.  They have all the conversion cables with the various adapter plugs on them.  Probably between those and some Radio Shack parts, you could make it work.

Checked and didnt see what I needed. Looks like I need to open it up and see where the mic audio runs to. Might just be easier to use the other mic since it has its own audio plug rather then trying to figure out how the original shares the plug on the ehadset when there is just two circuits on the plug (ground and shared)

What you originally described sounded like a standard aviation headset plug.  Spruce has the two-plug to single plug (helicopter type) headset adapter plugs.  I may be wrong.

Looking at some other pictures, looks like the mount for the mic is missing from the headset. Wouldnt take nothing to put that back on though

So you're saying that it would take something...

Yup.
