Hi
I have recently come into possession of 2 x Mk4 Helmets - they look OK, and the earpeices work but not the mikes but before I use them I'd like to have them bench tested/repaired
Can anyone advise of a good place to get this done. Ideally local to Norfolk UK.

I can second HSL. As I recall the mics wont work because they are incompatible with GA comms and well need converting.

Well I purchased 2 new mikes from HSL and had them locally fitted - headsets OK - mikes still don't work !!
I was hoping that would fix any probs - it's definately in the helmet as my conventional headsets work in the A/C.
Just wondered if anyone knew someone local to Norfolk who could take a look. If no joy then send to HSL it is................

The mikes in the mark 4 are different than conventional they are mil spec (low impedance I think ) you need converters to use them

I've got a MK4L which I use with a Mil to GA plug adaptor which has a built in Mic Amp....wont work without one...
This is the sort of thing you want but shop around for prices....
