    Thank you for your time and effort of finding the correct wiring for the Trucker mic.
    I was able to find a 100 nF Cap and soldered it in.
    I bought a can of Electronic cleaner and cleaned out the PTT switch and touched up all of the solder joints in the mic.
    The radio is working again for the first time in 45 years!
    I actually got a reply from a trucker a few miles away.
    I'm sure the radio needs to be tuned and I have no idea as to how to do that?
    Thanks again.
    Rob.
