So far, all the cases of a "loose" headphone washer that I've seen were
because the front panel pc board wasn't completely seated in the front panel
sheet metal. Rather, one edge of the microphone connector is binding in the
hole in the sheet metal, keeping the board from fitting all the way against
the panel. The Front Panel pc board will flex quite easily when the screws
are tightened and it doesn't take to cause the washer on the nearby PHONES
jack to be loose. Figure 37 shows exactly how the microphone connector
should appear when it's properly seated. The text at the top of page 29
describes how to seat it properly if it is binding. 

Ron, I too had the headphone jack problem.  After talking with tech support
I reveisited the assembly and am certain it's perfect, but there is still a
gap between the shoulder of the headphone jack and the front panel.  I
measured it with a shim guage but, unfortunately have forgotten the number. 
In any case I found a thin washer (from another 1/4" jack) that filled the
gap perfectly and intalled it over the jack threads behind the panel. 
Perhaps there was as parts variation from the vendor that could account for
the gap.
