[time-nuts] Finally acquired a 5370B

I have two 5370A counters, and both were afflicted by the "cheap socket"
After a year or so of intermittent operation (in spite of frequent removing
and reseating of the parts and application of Deoxit Gold), I took the two
boards with most of the sockets (processor board and memory board) to work
(where we have good desoldering equipment), desoldered all the sockets and
replaced them with good quality machined pin sockets from Mouser and all has
been now good for several months.
I am not sure if the 5370B has the same cheap sockets, but at the first
symptom (usually the counter does not power up normally, the display is all
mangled), I recommend to just go ahead and replace them. With the right
tools, it's no big deal. It took about one lunch hour for each.
