[Boatanchors] Fw: tcs 12 transmitter microphone modification details

Subject: tcs 12 transmitter microphone modification details


Gentlemen,
I have acquired a complete TCS12 system but with a useless microphone. I believe that there is a modification that enables a modern insert to be used or an 'electret' insert. Can anyone direct me to the modifications details please or mail me the circuitry.  This rig looks like it just came out of the shipping box, its been well cared for.
thanks in advance and regards
