[R-390] Filter repair

[quartz55]

"The connections between the resonators provide a precise amount of acoustic coupling between the disks. Any messing with them likely will nuke the filter characteristics."

I'm sure, but what have I got to loose except time?  I've done lot stranger and idiotic things and sometimes they work (to some degree).  About all I have to loose is wasted time at this point.  At least I still have another semi-good IF module with all the filters and the 8 and 16 in this one, however both do have some leakage which I'm sure affects the AGC.

Now how do I re-install those standoffs that are screwed to the bottom of the filter mounting screws without taking off the wires?  It was easy taking the screws out.  When I replaced Z501, I removed all the wires from the standoffs and re-installed. I actually did a good job, you can hardly tell but there's a bit more room there.
