Hi Doug-5er:

The spring you refer to, part #16, is what I believe to be a switch that mutes the audio whenever the handle is pressed in to change frequencies.  That spring is indeed present (see attached photo).  I also believe that, in order for the switch to mute the audio on command, it must follow the system's movements so it is in place to greet the handle when the handle is depressed.  My problem, I think, is that this synchronization of movement is not taking place.

The Service Bulletin suggested by others is getting a bit dog-eared from repeated use.  On page 1, second column, item 3 (Control Handle) step "c" says:  "Replace handle and reassemble using caution to have audio switch '16' in control slot on side of hub assembly".  

As you can see from the attached photo, I have positioned the switch/spring over what I believe to be the control slot, but the spring is well above the control slot and the hub moves without engaging the switch/spring.  

This project has been on the back burner for a couple of days while I await the arrival of a repro dial from RadioDaze as the original was kaput.  No point in futzing with it if it all has to come undone in a few days.

How does the switch/spring engage that control slot?  Is it simply held down into the slot by the peg on the handle?
