I have another thought. Back in the days when I was using the Paragon
in several African spots, I recall that I had a similar problem. After
removing the top cover, there is a small plain aluminum cover back
toward the right near the PA. There are a couple of sheet metal screws
which need to be removed before the cover comes off. Inside is a fuse
holder and a 25 amp fuse. That fuse may show some signs of heating. It
may even appear to be good. Sub a new one and test it before putting
the cover back on.
