I am prompted to say a little on the subject of inductors, due to a problem recently seen with a new model of guitar amplifier. The kit in question had obviously been designed by a graduate with a computer, because, while theoretically very good, it suffered from a total ignorance of the fact that inductors are affected by external magnetic fields. When switched on, the amplifier output a 50 Hz squarewave, due to pickup of the mains transformer field by a matching transformer in the input stage.
How the thing got to production without anyone trying it I shall never know.
