That reminds me of an article, perhaps in the late
1960s, in QST by John Troster, w6ISQ, author of all manner of joke articles. The title
was something along the lines of ?Murphy?s laws of electronics?.
One of them: ?A transistor, protected by a fast acting fuse, will protect the fuse by
blowing first?.
Another one: ?A dropped tool will land where it does the most expensive damage ? this is
know as the Law of Selective Gravitation?. (That came with a cartoon showing a hammer
nudged off a shelf, on a direct path to an expensive vacuum tube in an open chassis on the
bench.)
Amplifiers oscillate, and oscillators don't.
(Software equivalent: Constants aren't and variables won't.)
