Are you ready to be heartbroken?

2 new filter wheels have arrived (see work-related posts passim). I've just tried one on both of the 'scopes, and it works on neither.

Next I try the other one, and then when I inevitably find that it doesn't work either I suppose I ask for both of the instruments to be completely checked by one of their engineers, and brought into a fully working state pronto.

Spoke too soon. As of the first attempt, the other one works . . . although I'm sure I'm tempting fate by mentioning it in public. This is our fifth filter wheel. The first, third and fourth were DOA and the second failed after less than two weeks. Hopefully this one will last. Hopefully.
