Default Re: "Duck" telephone

Old Electret-capsules do seem somewhat fault-prone, I guess they're a bit like the crystal microphones/gramophone pick-ups of yesteryear that often don't age gracefully (I have had problems with electret capsules in two-way-radio mobile microphones - the temperature/humidity excursions inside a car can't help their longevity).

Good to hear you solved your duck's problem though! I've always had a bit of a weakness for 'gimmick phones'.
