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.

Something that is pulling a supply into current limiting has to be nasty.
Pop the covers. There is a heavy read wire that feeds Dc to the final. Remove
that wire (may need to trace it back ) and apply power.
Sounds like a shorted driver/final

Hi Phil!
Thanks for the reply. Warmed up the scope and the AC ripple on the
power supply is less than 75mV peak to peak.
I got out a 10amp, 13.8VDC supply and tried it. It seems like it tries
to come on, all the LED's light, a relay clicks, then the power supply
goes into current limit, everything shuts off. The power supply will
recover, put out voltage again, all the LED's light etc., power supply
goes into limiting and does it again and again... :(
(I didn't let it do it more than three or four times before turning it off)
So I'm thinking that power supply is okay and the trouble is indeed
inside the radio. :(
thanks much and 73,
ben, kd5byb
