Thanks Cliff, that's probably the equipment I was thinking of, quite
remarkable performance for its time. Keeping to the Tektronix theme,
the time line shows the 519C as a 3 GHz scope but with only 180 vols
/ cm sensitivity. I can't recall anything about this version,
perhaps a few hand made specials for the nuclear laboratories? Does
anyone know any details (manual, hen's teeth??).

It's interesting how most of the scopes current in 1983 used MCPs
and mention was made of one failure due to the MCP after 9000 hrs.
In light of discussion about the 7104 MCP fragility that sounds like
a long life.

there was discussion of the 7109, third party

might have been discussion around the old 519 without

limit. Does anyone else remember it or are the pixies
playing with my mind?

Not a scope, and not CSF, but you got the French
