Getting about a 2 second hum after I un key. Even if I just flick the Mike. Then it’s gone and the receive is dead quiet. Any suggestions on what is causing this appreciated!

Hmmm. A radio that's 48 or more years old. No idea how much of the required maintenance has been done. If all the electrolytic capacitors have been replaced, that's one starting point to troubleshoot a problem.
But if all the electrolytic caps are original, chances are that one or more of them is the culprit for this fault. But which one? Or which two?
This is not a common sort of "they all do that" fault. Some of those can be linked to a particular symptom. But not this one, at least in my experience.

Fixed. It was a bad 6GH8A tube.
