Sepura stp9000 accessory port

[Redgren grumbholt]

Hello wire free alliance!

We have had an upgrade at work to sepura stp9000's. This has rendered my dependable comtac xp ear defenders with mic and the peltor PTT out of use.
i am currently trying to change the connector to work on the accessory port of the new STP9000, I think I've worked out the correct pinouts after borrowing a friends but now need the correct jack connector to use.

My question to the forum is does anybody know where I can buy a fresh connector to use?

Thanks in advance!
