Miscellaneous Test Equipment
This old Tektronix scope features dual beams, and a differential amplifier for each beam.
I don't recall whether this is a Tektronix, but it has LOTS of parts.
When you wanted a frequency counter in the 60's, this is it. All tubes. Lots of them.
This is the Philco signal tracer. When I worked in the radio shop, this was an indespensible tool. My boss said that he bought three of these. This is the only one that wasn't stolen.
