No focus on WG6100 - the solution

        Turns out the tube socket on the neck board was bad. The focus-grid
pin had broken off internally; it would make contact while cold, but as it
warmed up the broken edge would separate and break the connection.

        (What fooled me was that it was a _gradual_ loss of focus; I'd have
thought a broken socket would either not work at all, or go out suddenly.
I'd _also_ have thought that you'd hear some arcing if the voltage was
actually jumping the gap, but apparently not...)

        Does anyone know of a good source for CRT sockets OTHER than
cannibalizing them off of other neck boards? Fortunately, _this_ time I
had a dead WG6100 neck board to steal it from, but I doubt I'll be so lucky
the next time this happens...
