My favourite story on inept electronics techs is from a transmitter fault on one of our type 12's about 30 years ago.
I was called in to fix a "minor" problem when the transmitter would not tune the aerial in automatic.
When I got to the ship the transmitter was in lots and lots of bits strewn over the floor of the transmitter room. had a good look and listened to what the symptoms were.
Four hours later I had the transmitter back assembled fixing a couple of minor faults on the way.
When the transmitter was finished I turned it on and proceeded to test it. Yes the fault was still there exactly as described.
I walked over to the main 3ph 440 v supply panel and checked the fuses. Yes C phase was O/C. I replaced it and everything was back to normal operation.

PS I guessed this was the fault as soon as I heard the symptoms although they could trick the unwary. The transmitter had a 1KW SSB linear amp running from six phase AC rectified without out filters. The amplifier being linear does not respond to the ripple. However the the loss of a phase made it into a two phase half wave rectifier which of course ruined the linearity. The power indicator being a peak voltage device still registered full power but the average power was only a fraction of the normal and not enough to drive the aerial coupler.
