Help! Urgently need Barrett communication specialist in Melbourne

Hi Everyone!

For mysterious reason my Barrett 950 transceiver puff some smoke when I tried to reconnect it. Funny enough there was no power supply - I removed fuse before starting. So only possibility that it catches parasitic ground current. I opened it and found that signal cable (that one that goes to headunit) fried inside transceiver itself, inside head unit and inside cable. So I urgently need some help (both technical and parts-wise) in Melbourne - I am heading to Simpson this Saturday! In the past I used John in Brunswick and he was nothing but great, but he sell his business a while ago to some Indian fellow - I seen him once and he was only happy to sell me new mobile and he was completely and utterly useless from technical prospective of view.

Any help would be greatly appreciated.

Thanks
Serg
