Well, I accidentally transmitted on 435 into an unswitched 70 cm receive preamp... That would qualify I'm sure, as one of the better ones. Fortunately I realized what I did and ordered 10 replacement transistors, knowing that I'd prolly do it again.

Thanks to all who replied both here and off-list, the embarrassing results of the station investigation reveal a major operator error! :-[

The worse one can be your coax not plug in :) but we never know could be you have a better one?

As stated above i for myself burn 3 and 2 to go... but this time they are relay protected. Not a 100% fool proof solution but since they are up in the tower all things are going smoothly...6 months now!
On my 3 burn out even one with the relay protection who switch the preamp out of the line when no DC power is present, fast CW keying can destroy it or using an external DC power injector who keep the preamp in line and when just a simple mike fell down on a straight key it produce the fatal white noise scary situation where nothing happen when you switch the preamp back an forth...
The word "mistake" has been invented by the tall guy with a beard and to make sure we will not forget his name he set up some situation making us repeating his name numerous time...
If we are not alone in the universe you are not too!
