I was suicidal; the jacks looked happy enough having time out.

The spring is a piece of brass wire, like one of the fine strings. It
comes in from the back of the jack below the tongue, describes an
upside down v-shape, and then a straight bit of about a centimetre
goes up a groove in the centre of the tongue. The angle of the
upside down v is adjustable, but when the straight bit goes wrong
its very hard to get it to stay in the groove.

Sorry, it's not a noisy jack--definitely the key, which looks like all
the others. (Although I suppose the jack could be helping the
propulsion.) It's too new for any felt to be very worn. A little too
much force and this key goes down and hits the wood below--it can
happen with all of them, of course, but I find it suspicious that I'm
more inept here than elsewhere. It's not as serious as the other
problems. Maybe I should consider it the miner's canary.
