[Elecraft] KPA1500 LOW GAIN FAULT

Since the barrel is knurled and has no flats for a wrench it seems certain that a wrench was not what the designer had in mind.

I think that’s where folks go wrong...when the plug doesn’t set into the grooves. I almost need pliers to remove the plug when disconnecting it. At least 60 years so far this works...
