[R-390] Sources for HP410C AC Probe

[wb5uom at hughes.net]

Ray,
Did you hang out around a movie theatre a long time ago?
Not many people know how theatre film is delivered.

The "35mm film can" part gave me a image of a large 7 pound object (1
reeeler) ,with a little probe sticking out on one side  and a place to store
many feet of probe cable when not in use and one trying to hold it with both
hands, placing it at he proper point to be measured.
