I am wondering what must be the good reason why kit suppliers provide
crystals with two wires when crystals with three wires are available -
the middle wire being connected to the external metal case, thus making
earthing of the case a very quick, simple and safe operation.
Every time I have to solder grounding wires to the case of a crystal, I
get the nervous jim-jams, as I am afraid that I will damage the crystal
by overheating, although I try to be ever so quick - a bit like my
countryman, the late Errol Flynn.
I guess the answer must be cost.
