I have a friend in Thailand who recently zorched out L5 in his 77DX. Believe it or not, a small lizard got into the tank circuit and when he was tuning on 80 meters, L5 got extremely hot - to the point of cracking both of the torroidal cores! Does anyone know what specific cores were used or if not, what the approximate value of inductance that L5 should be? I assume these are iron powder cores. I'm trying to help him remotely or perhaps send him a replacement

  If they are broken in two (or more pieces) I have a friend that swears that after gluing broken powered iron cores back together they work just as good as new, after being epoxied back together,
Clamp them together while the epoxy sets.  (a radiator hose band might do)
