Well, I'm not ready to pronounce it fixed yet but it's now been working
for half an hour which is the most it's worked in a day now. I pulled
the face plate off and checked to make sure all the cables were firmly
seated and then turned the radio on and the main receiver finally sprung
to life. I then noticed that it would die if I lightly tapped on the
boards mounted to the back of the face plate. I thought maybe the
boards didn't have a good ground connection so I snugged up the screws
on the boards and the two ground jumpers to the main chassis and it's
been running fine for a while now. Most all of those screws were very
slightly loose (quarter turn to a half-turn). I snugged up the
accessible screws on the other boards while it was open. We'll see how
it goes.
